Ford 7.3L Power Stroke (1999-2003) :: Code P1316 - New IDM?
What do I do? Do I need a new IDM?
View 3 RepliesFord 7.3L Power Stroke (1999-2003) :: Bad Stutter / P1316 Code
Wife put fuel in my truck drove it home and as soon as I started it back up it was running rough as hell. When I got to the freeway it got real rough at 1500 rpms in overdrive. If I bring it up over 2000rpm it's better but still feels rough. When I got off work and started it up I got the p1316 code.
I did some research tested plugs on the valve covers a few pins were over 5ohms so pulled the valve covers did the 50cent mod to shimm the under valve cover wiring harness. All pins are around 3.5 ohms. It did not fix the problem.
I then dropped the tank thinking maybe the pick up was gunked up. I've read all the horror stories about the delamination in Ford tanks. Good news is that I have a plastic fuel tank. Bad news is the screens though dirty weren't dirty enough to cause my problems. Where should I go from here?
Ford 7.3L Power Stroke (1999-2003) :: Misfire Code P1316 / Smokes Bad If Rev It
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.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Truck Missing And White Smoke Coming Out - Code P1316
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.

The bolt that holds the dipstick on the valve cover. i have tried for ever to get this thing off. soaked it , got a skinny wrench on the nut underneath but think it might be stripped (1/2 inch grinded out a little). going to try and get a set of skinny wrenches tomorrow , mine bent. tried vise grips on top of the bolt and put a box wrench on the nut , and gave it my all. The damn thing won't budge.
Also, any tips on the rest of the valve cover bolts. I had to remove some from inside the fender well but barely got to them. My question is not getting these out but getting them back in. And how the heck to you torque these things??? The bolt i mentioned above is creating problem, and I only have so much time

View 2 RepliesFord 6.0L Power Stroke Diesel :: Code P2623 For Stuck IPR Valve
My son is joining the site as we try to diagnose his first diesel. We checked fuel flow, and the bubble test. We held the valve down in the oil filter and watched it fill up in about 10 seconds and see it register on the dash gauge.
My Scan Gauge say it pushes 180 RPM while cranking, but it only gets about 225 on the ICP sensor and the IPR instantly maxes out at 84. It has thrown a code P2623 for a stuck IPR valve.
I hear a hiccup in the crank, but I'll let y'all listen and tell me. Will post YouTube link of it.
What are the chances of it being just a hole in the IPR screen or bad valve? I'm afraid we have a HP leak and need to do the air test to find it. I've never done that test and barely hear (rock concerts), my son hears but doesn't know what to listen for.
Ford 7.3L Power Stroke (1999-2003) :: Idle Roughly - No Power - Got Codes P1280 And P1316?
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 3 RepliesFord 7.3L Power Stroke (1999-2003) :: 2001 F250 - Fuel Leak - Not Water Separator Valve O-Rings
I have a very small fuel leak in my 2001 F-250. I was going to just let it go until I needed to do other work (since I get 20mpg city and 25mpg highway), but I went to a "new" inspection guy, and he flunked me. So now I have to fix it. And for all I know, my mpg and fifteen other things will break when I try to fix this.
Today I spent 4 hours in the heat putting in two new o-rings on the water separator valve. But the truck still leaks fuel. Climbed up on top of motor while it was running and looked, but I don't see where the fuel is leaking out.
Online research suggests to me that the next most-likely culprit is a steel fuel line that wears through from vibration and chafing. Is that correct?
This truck is so eaten up with rust (came from salt belt) that I bought a LOT of fuel line stuff a year or so ago, so that when things started falling apart from rust, I would have the parts on hand.
Now I'm wondering whether I already have the part I'm likely to need.
So far, I have bought:
1. Dorman Fuel Supply and Return Lines
2. Riff Raff Diesel High Pressure Crossover (HPx)
3. Riff Raff Diesel Fuel Rail Crossover (FRx)
So my question is, am I likely to have something to replace the part that commonly leaks on these trucks due to vibration/wear/chafing ... or will I still need to buy another part?
I'm thinking that one of the two lines in item #1 above is the problem child...
Ford 7.3L Power Stroke (1999-2003) :: Fuel Gauge Stuck On Full
Well besides the pyro breaking friday BEFORE live tuning,and the exhaust leak I gained on the way to Texas(not inpart of the pyro not working). Now the fuel gauge is stuck on full. It looks good,200+ miles and still on full. Could it be the gauge,or possibly just the sending unit? Maybe a fuse?
View 14 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.
View 13 RepliesFord 7.3L Power Stroke (1999-2003) :: Tips To Remove Stuck Fuel Filter Lid
I am attempting to change my fuel filter - have a new Napa unit complete with new lid.
I can not get the old one off (this alone tells me it's been on there too long). The hex is 26mm and all I have is a 26mm box end. It just rounds the corners of the plastic hex off.
As the new filter has a new lid, I am using a steel chisel and hammer (in a CCW direction) at several places on the top flange. I have also smacked the top flange liberally to get it to let go of whatever is holding it.
I'm about to get out my map torch out and warm up the plastic but would rather not produce a flame on something with fuel directly behind it.
