I have a 03 7.3 runs like crap. buzz test says cyl 2 and 4 have high to low side open. the only code that's hard is p1316. it also says cyl 1-3-4 fail balance test but not always some times only 2 fail.... I ohm tested injectors all the way to the idm and all are between 3.1 and 4.2 ish. So I guess I can rule out wiring. it smokes pretty bad if I rev it. it was running good till I parked it for 2 days. I did put HSS in oil 2 weeks ago to try clean out little rough acceleration. I did find my ipr nut fell off and spacer ipr was just floating around on the shaft I put that back together it was laying there.

Here's the story. Truck has showed no signs of rough running. Wife drives truck around town. Truck up to temperature and doing fine on a 90 degree day. Stops at red light. Makes left turn engine light comes on truck seems to be running on 4 cylinders. Pulls over light goes off engine idles perfect. Pulls back on road light on no power. Gets truck to a local friends house lets it sit til I get off work.
I check for codes get p1316. Drive truck toward my house no problems for 4-5 miles then does the above with me. Limp it home. I know it is pointing at a wire problem to injectors and or IDM. Did a buzz test passed fine. Plan on pulling valve covers and looking for the usuall things. Any thing I am missing? What will a kOEO test tell me? Should I run one? How common is IDM to go out? One last thing just put a rebuilt transmission in it 3 days ago may be unrelated it seems to be doing fine.

Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 Sluggish - CEL On - Code P1316
Just a heads up when it comes to this code. Today at work I was working on a 2000 f350 that the driver neglected on telling me he had a CEL on and truck was kind of sluggish (drivers are idiots they cant tell the difference) but no miss or any sign of problem except the CEL (he had electrical tape on the cluster. Well I put my AE to see the vitals and immediately code p1316, so I went to do a buzz test revealing that cylinder 1,3,5,7,6 were short to open circuit (forgot the codes) but they all sounded healthy. My next step since it was a quick and easy to do was to check the passenger side uvch to see for burnt pins and what not but everything checked out.
Checked the driver side #6 cyl for the same problem bit a no go. I ohm tested the injectors all of them checked out, wires all the way to the idm checked out so at this point I was in my atemp to see what the hell was going on I decided to install my obs idm on, and guess what happened next it worked immediately the sel did not come up and when I test drove it, my god it felt like a new truck.
Just a side note the idm, had no sign of water damage, and like mentioned to the untrained person most would not tell the difference on how it ran. To anybody that has checked and can't find the problem make sure you really and I mean really check your IDM really good.
Ford 7.3L Power Stroke (1999-2003) :: Code P1316 Thrown When Engine Is Cold?
I keep getting my SES light coming on in the morning when my engine is cold. I'm getting code p0603 and p1316. I was told the first one is just from using my tuner. The second code is the injector driver module, just trying to figure out what is causing it to throw the SES light only when cold.

I'm running a 2000 f250 7.3. The truck has been stumbling for the last two years intermittently. I did the 50 cent mod last fall to the uvch's. Changed CPS, idm, air flow sensor. This last week it finally threw the p1316 code so I have something to go off of. Trucks falling on its face so I parked it. Tore it down last night. Ohm tested all the injectors last night cold and all read around 3ohms. Tested the uvch's and continuity looks good on both sides. Tested them through the valve cover seal, tested fine. Tested them through the first harness and fine. All I have left to check is all the way to the idm. Still no luck finding the problem.

Well, truck is throwing me for a new loop the day I pick it up from the body shop (crazy, right?). I started out driving it and had a blue haze - I figured it had some air left in the system from doing my injectors so I left it and it cleared up after about 20 miles. I noticed that my SES light came on while idling at a stoplight, but went off when I took off. Figured it was a fluke and kept on getting on.
Well, next light it does the same thing - idle the light is on, take off the light is off. Reading the code yields P1316 - so I pull over and running a buzz test to fetch the IDM codes. Guess what? No codes. All sounded fine, so this is where I got really confused as I'm getting huge mixed signals from this truck suddenly.
As I got to watching my gauges, I noticed that I was idling around 10.8 IPRDC and 530-560 ICP, and when I would get about 16-18 IPRDC the code would go away. Did a near-WOT run when getting on interstate as a test to see how it'd do, and saw IPRDC get up to 98% - the highest I have EVER seen it get on this truck (no idea if it is related or not). I have a log from moving around the lot that I will try and upload soon.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Got Code P1316 - Injector Wiring Harness?
I have a 2000 Ford F550 7.3. I bought a Superchips programmer to read the codes on my truck and up pops this P1316, so I did some research and found out that the most common problem is the injector wiring harness. I bought new valve cover gaskets and the injector wiring as well because the truck is old and I figured new wires wouldn't hurt.
So after installing the new wiring harness and gaskets I'm still getting this Code! The truck idles rough and serge's sometimes, also there is a lack of power and some shaking between 40 and 50 miles per hour, however form 50 to 60 MPH seem's to be just fine. I don't trust the "Mechanic Shops" around here and will only take the truck in as a last resort.

Recently I have had many problems with my 2000 7.3l .... The one I cant get rid of is the p1316 code. I have changed out the uvc harness and gasket with new ones, then removed valve cover's to double check connections again and they are fine. I am getting white smoke and the truck misses. I do not have a advanced reader for the codes just using my edge programmer. I have also disconnected the battery and cleared the code but it comes right back.

Started my truck yesterday and drove about 1/4 of mile and all of a sudden I lost all power but was lucky enough to creep back home. Had a friend put it on a scanner and it spit out P1280 and P1316 codes. My truck will start and idle rough but has no throttle response and no power. I changed out the CPS and ICP and the problem still exists. I got an infrared thermometer and checked the heat coming off each manifold and the driver side was reading about 200 while the passenger side was reading about 75 while at idle. Pulled valve pan cover off the passenger side to check and see if the harness came loose and everything looked fine. So my question is do you think this could lead to a bad IDM?
View 9 RepliesFord 7.3L Power Stroke (1999-2003) :: 2001 - P1316 IDM Codes Detected Coming Back Upon Start Up
I've been battling this truck for over a month now and starting to go a little crazy, It's a 2001 f350 7.3L, with a "used" 7.3L engine from a 1997. Transferred all the necessary parts to make it happen. Keep getting the evil p1316 idm codes detected coming back upon start up. Anywhere between 5-30seconds after starting the left bank dies. I've gone threw and replaced the IDM with a reman unit. New valve cover gaskets (with new harness). even went the extra mile and put in a new power wire (for the driver side) running directly from the new valve cover into the IDM bypassing a connector above the left valve cover. All injectors are checking out around 3ohms. With glow plugs all around 1-2ohms. What's interesting about this is, I can disable any one of the injectors on the left bank (doesn't matter which one) and the engine runs great considering it's down on one cylinder. But when I hook up that last injector it will kill the whole left bank again.

Well, long story is that I starting have problems with my 2000 F350 Dually 7.3 PSD about 6 months ago ( ~10K miles ago ). I have sunk almost 5K$ in mechanics and the problem is still present.
By troubleshoot, I do not mean try this, try this, as that has been what is happening. I mean making test measurements and diagnostics. I am fairly mechanically inclined, but I am no mechanic. Looking for primers on how the 7.3 PSD works.
Symptoms: After the truck sits 12 to 14 hours, it starts and idles fine ( ~ 700 RPM on the 'Dash Tach' ) just as it has always done. During the first 5 miles of driving it, the SES light comes on and it sputters, stalls, and vibrates as if a couple of the injectors are not firing. It then clears up and the SES light goes out, except that it idles at about 1200 RPM ( 'Dash Tach' ).
It runs fine like this the rest of the day, If I shut it down it will start right up and run fine, but it has the high idles. Only if it is shut down longer than 12 to 16 hours do the symptoms, other than the high idle, reappear. The high idle is constant. Also mpg have fallen ( 13 opposed to 16 ).
It does not seem to be related to ambient temperature, or the amount of warm-up idle. I have idled it for three hours on startup and it is fine, until I drive the first 5 miles or so.
Now, I have had three mechanics work on it and they have replaced: the ICP sensor ( 3 times ), the Fuel filter ( twice ), drained, flushed and refilled the HPOP, replaced both sides of the valve cover wiring harness, put in a new IDM, fuel heater, CPS sensor ( 3 times ), fuel pump in fuel tank, EBPV ( not sure what this is ), and the last straw was saying the injectors needed to be replaced ( or at least the O-rings, but while we are in there you might as well ... ).
I bought a cheap code reader and it says: P1316 & P1211. I believe these are the same codes since day 1.
Ford 7.3L Power Stroke (1999-2003) :: Shudder / Stutter And Shake While Accelerating
I have a early 99 7.3l that seem to cut out and shudder while accelerating at low rpm's below 2000 once I am above 2000 rpm it seems to go away similar to a dirty carburetor thinking injector problem...
View 2 RepliesFord 7.3L Power Stroke (1999-2003) :: 2000 - Bad Miss Or Stutter / Knock At High RPM And Deceleration
2000 F250 7.3L ZF 6spd 4x4 regular cab long bed 253k
DP F6 chip, 4" exhaust, WW2, EBV delete
I run 5w40 Rotella Synthetic. Oil was changed about 1,000 miles ago. I also added a quart of Hot Shot stiction eliminator. I use Power Service and Stanadyne lubricity in every tank. Fuel filter is new.(motorcraft)
For a month or so its been acting weird. I get a stumble/miss/stutter, at random, but mostly under hard acceleration and high rpm (specifically approx 2500-2800rpm). It will also do it on decel when I lift after accellerating . Recently, I noticed it is also idling roughly. The engine is shaking and it feels like a miss. When it does its "thing" it sounds like a single "knock". Occassionally, it sort of sounds like an injector "buzzing". I've been using the "stock" tune for the last few weeks, to minimize any chance of engine damage, as I have to drive it. Turning up the chip makes the problems more noticeable and happen at a lower rpm. The truck has plenty of power, and pulls hard, except for the "stutter". If I hold my foot in it to "push through" the initial stumble at 2500 or so, it will keep going a few hundred more rpm, and then really start bucking.
There are no meaningful codes. I DO have:
EBV related soft codes - makes sense since its deleted.
Overboost related codes- from turning the chip up - won't happen in stock setting
A soft code for the back pressure SENSOR. I have a new one and will be cleaning the tube when I get a chance. I unplugged the sensor and it made no difference in the miss issue.
I have recently done the following in pursuit of a solution to all this:
New IPR (autozone) valve and pigtail
New ICP (motorcraft) and pigtail ( sensor had oil in it)
New CMP and pigtail. (2 actually. First a standard pc139 for the obs, and currently a Napa echlin correct for '00) No change. Although it initially had the dreaded Ford small head light grey sensor and failed cct for #3 & 8. After the cps change, it passed cct.
Accellerator Pedal Position Sensor. It would not read any higher then 3.95v at wot, and only 0.50v at idle, so I installed a new one. After adjusting it a little, I have 0.76v at idle, and 4.02 at wot. Didn't affect the stumble issue, but it seemed to greatly improve/eliminate my parking lot speed "bucking".
I just did the UVCH's. The passenger side was pretty much unplugged. But they all looked good. No burnt, melted,or chafed wires anywhere. I probably could have just plugged it back in, but I changed both sides with new Motorcraft parts anyway. I did the gaskets and the uvch, but not the engine side harness/pigtail, as they looked ok. I also did the 0.50 mod as a preventative measure. After seeing the unplugged harness, I really thought this would be the end of the problem, but its not. Very frustrated.
As a side note, I was surprised to see that I have 8 AD injectors, and not an AE in cyl 8.
I have an old outdated snapon scanner. Its only good up to '99, but I am able to scan my 2000 as a '99. I think I'm missing some pids though.
I can do cct and buzz test, but no PERDEL readings.
As far as ICP, it idles at about 450psi, at approx 12% IPR dc. On a brief 2nd gear wot run, it will hit (and hold as long as I have road to stay in it) a little over 2900psi, at 41-42% IPR duty cycle. I did notice, during these near instantaneous stumble events, ICP would flutter on the scanner about 75-100psi. Its almost too quick to even see it.
Ford 7.3L Power Stroke (1999-2003) :: Crank No Start Sometimes - Stutter / Stalls And Slow Acceleration
I have 2001 F250 7.3L 261k miles.
Over the last few months, I have noticed that my truck is taking longer & longer to start after sitting for a long time (i.e. every morning, after work, etc.) When the problem first started (3-4 months ago) it would crank for 2 seconds & nothing so I would turn it off, let the "wait to start" light go off again (depending on outside temp 10-20 seconds) & then it would crank & usually fire right over like it was new. That seemed to happen only in the morning when it was 70 degrees or colder outside but no problem after work when it was 80+ degrees.
As the weather has gotten colder, it has gotten progressively worse. A couple of weeks ago, it was in the 40s in the morning & it took a solid 8 or 9 minutes of cranking for a few seconds, then trying again before it started. Once it started it did "chuga chug" a couple of times before it smoothed out. Last week when it was 16 degrees in the morning, it wouldn't start at all. I tried for a solid 15 minutes before I gave up.
I will say that as it has gotten worse over the last couple of months, I have noticed that it's cranking w/o firing but I will hear it fire once or twice per crank before it will fire up & run. Once it starts, it runs like a champ. No studders, stalls, slow acceleration, etc. Pulls like it always has. The weirdest part about it is that once it starts & runs for 30-60 seconds, I can shut it off & it'll fire right up every time. If I get it up to full operating temperature, I can go back & start it right up 2 or 3 hours later w/o a problem.
I did notice my oil cooler is leaking pretty badly (that will be fixed this weekend) & my valley has fluid in it but it's hard to tell if it's diesel, oil or a combination of the two because my truck is setup to run on WMO (waste motor oil). I have dual tanks so the OEM tank is diesel & the auxillary tank is WMO. I have 2 mechanical fuel pressure gauges on my fuel bowl, 1 pre & 1 post fuel filter as well as an aftermarket Walbro fuel pump. The fuel pressure when running on WMO has always bounced a little bit between (65-75 psi) but the fuel pressure on diesel has always held solid at 75 psi until recently when I have noticed that it flutters a very small amount between 73-75 psi.
I have verified that the GP Relay works & was leaning towards a glow plug problem but considering it was having troubles at 70 degrees ambient temperature, I'm hesitant to think that's the true problem. I think that might just be adding to the problem. I live in the south so my truck doesn't have a block heater but I'm going to add one this weekend when I replace the oil cooler gaskets & o-rings.
I'm also going to pick up a new Android tablet today (replace my broken one) so I can use the Torque Pro app to monitor ICP, HPOP & InjPW. Finally, I had a DP Tuner chip on it & to remove that as the possible cause, I removed it & the same symptoms continued.
Ford 7.3L Power Stroke (1999-2003) :: Pop When Accelerating With Turbo Spooling Up And Lost Power - Code P0475
As I was getting ready to leave town with the tractor loaded up, I was accelerating with the turbo spooling up when I heard a bit of a pop and lost power (engine still running and all, just very low power like you get when the turbo fails). I wasn't far from the shop so I came back and started getting a lot of white smoke out of the exhaust, it doesn't smell like diesel, probably more like oil. Definitely smoke, not coolant. I pulled it around back and shut it down to go grab AE and scan it and it shows a P0475, starting it back up has light smoke at idle and it idles fine but as soon as you give it any throttle it starts smoking pretty badly.
Researching it looks like the most likely cause for this is the EBPV itself but before tearing it down that far. This is the only code it's showing.
Truck has 272k on it, turbo was rebuilt a couple of years ago but we didn't do anything with the pedestal at that time. I guess in retrospect, I probably should have done the EBPV delete and the resistor fix then but I didn't think about it at the time.
On another note, my AE is not showing any of the system test for some reason, the drop down is blank. I have version 7.0.1, so it's an old version but I'm working on an old truck, so... What that might be? I've got the truck pulled into the shop now to let it cool down. I'll probably let it sit overnight and take the turbo and EBPV out tomorrow unless someone has a better suggestion...

Truck was towed into my shop for no start. Mechanic diag as hpop pump. He is no longer here. R&R hpop with thourobred reman pump. Truck still a no start. only code is for EBP. Spacer is behind tin nut of ipr. Starter spins motor as it should. No blown fuses. WTS light works. No oil in icp or ipr sensors. GPR voltage is good. Tach moves when cranking. Disconnect ICP still no start and has 65% duty cycle. IPR has 500-1000psi the first 2sec of cranking then it drops and fluctuates 180-480. Add direct power to ipr and get 660psi the first 2sec of cranking then drops
