Ford 7.3L Power Stroke (1999-2003) :: 2001 - Injector Engine Wire Harness
I'm trying to find a part number for the wiring harness that sits on top of the motor and plugs into the valve cover gaskets. The previous owner replaced the pigtails but the wires were cut so far back that there is virtually nothing left coming out of the harness. What the actual harness looks like other than it has the 9 pin plug on it or whether both sides require an individual harness. What is the part number or picture of said harness. Just in case.... it's a 2001 7.3.

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) :: 2002 - Loud Bang And Lost Power In The Transmission
Last year I did some major work on my 02. Painted it, new injectors, 38R, and once it was back together, the transmission went south in a month. Got a Ford reman HD4R100. Shortly after the install, when in reverse, the torque convertor would lock up when you stepped on the throttle. As soon as you let off the throttle, it would disengage. Thinking it was a tranny issue, got another one from Ford. This one has been in the truck for about 9 months. And it seemed fine until about a month ago. It started doing the torque convertor lockup thing in reverse like the last one, but not as often.
Then last weekend it did it every time I put it in reverse. Then yesterday, while pulling away from a traffic light, there was a loud bang, and lost power in the transmission. Once stopped, I found out it has manual 1st and 2nd, but nothing else. No drive, overdrive, or reverse. I personally believe something electrical led to these issues, and ultimately, the transmission failure. I know the truck is not stock, but I do not run it hard very much. When it went bang yesterday, I was not being hard on it. Where to look at what is causing this?
Ford 7.3L Power Stroke (1999-2003) :: 2002 F250 - Lost Power And Suddenly No Throttle
Comming back from hunting today my truck suddenly lost power and stepping on the accelearator had no effect at all. We were on the highway thru the mountains but on a fairly level stretch for a few miles. Managed to pull the truck and toy hauler over and the engine was running fine but stepping on the accelerator had no effect. The check engine light came on every time I stepped on the throttle and went out when I released it. It started fine but no throttle response. Switched around a bunch of relays and checked the fuses and still nothing.
Not liking my parking spot i tried to see if it would move down the road at an idle but it would not. Then I thought to try it in 4 wheel low and as the shoulders were soft it wouldn't move forward so tried reverse and went back a foot, forward again and moved a foot and a half. did this several times and all of a sudden the throttle responded, took it out of 4 wheel and it ran fine all the way home. What would have caused this? I was ready to call a tow truck which would have been several hundred dollar bills for where we were and with the trailer
Ford 7.3L Power Stroke (1999-2003) :: 2002 - No Start After Harness Shorts
While engine was running. brake switch "recall harness" shorted to exhaust manifold blowing fuse 22. truck died instantly. found the short and replaced fuse. checked all fuses good but no start since. WTS indicator stays on. tried a new GPR and a new CPS.
Does IPR and brake switch (on master cylinder) share fuse 22? fuse 22 holds now (when wire was fused to exhaust manifold it blew as soon as key turned on). unplugged FBH no change. recall harness "beeps" good and wires do not appear burnt. also shuffled relays around in central junction box.
Could formerly access OBD2 port with superchips programmer but no access now. fearing the worst, but hoping maybe bad ipr sensor (or another sensor) could cause this. Is it likely or not that this short fried the PCM?
Ford 7.3L Power Stroke (1999-2003) :: 2002 F250 - Truck Lost Power Then Died - No Codes
I have a 2002 F250 Super Duty. Was driving it and it started to lose power and shut off. Then wouldn't start like out of fuel. No engine light no codes. Truck has 155k on it. So just because I replaced fuel pump. Truck runs but not right it's ruff no power kinda back fires in exhaust. I check wires and plugs under valve covers all seems ok. I ran truck and pulled each injector loose and engine would stumble. As in they are working. I replaced cps. Just because still the same. Then the truck started running right. But the truck runs but has knock but knock goes away and truck has full power. Yes oil is full and I change it regularly. The problem is off and on like electrical.

I bought this truck a few months ago. After trying everything under the sun to try and rectify a poor running problem, it was realized that injectors needed replacing. Ended up putting in 160cc/30% unlimited diesel performance injectors. The truck has a rough idle and surging problem. After trying to install the chip from gearhead, the truck didn't run any different, ultimately (according to the shop doing the install) smoking the ECU. New stock ECU, same problem. Goes good under throttle, just idle is bad. I get weird looks at the gas station. People think it has a big cam.

Ford 7.3L Power Stroke (1999-2003) :: All Power Lost / Engine Shut Off
So on my way home today I lost all power, the engine shut of and i coasted to side of the road. Went to try and start, nothing. When key is in the crank position the gauges were jumping all over the place, also accompanied by a lot of clicking from behind the dash. Nothing happened when tried to crank. No power to windows or even emergency flashers.
So i get it towed home, and of course it turns over. But this only lasts about ten seconds, then dies. I could do that a few times and then back to no power at all. Even at times with the keys out of ignition it will still click and make a lot of noise.

This is an issue I started chasing after having all the injectors replaced on my aunt's F-350. We had them replaced due to hard/no start on cold (dealership told her they needed to be changed). Unfortunately, I did not get the buzz test results before changing the injectors.
So far that has been replaced:
Injectors
ICP (was leaking)
IPR
both UVCH
IDM (twice)
The issue we are having right now is that only 2 injectors (#6, #7) buzz properly. Initially when we changed the injectors, it did start but didn't seem to run quite right. We did the buzz test and at that time and injectors 1,3,5,6,7 would buzz strong but the rest were weak. After some forum lurking, we suspected that the IDM was faulty. We purchased a refurbished one and after we changed it, only injectors 6,7 would buzz strong. Thinking a faulty IDM was sent it back for a replacement. While waiting, we decided to put the old one back in figuring it would go back as it was before but only 6,7 would buzz strong. We receive the second IDM and same thing, only 6,7 buzz strong. We did a continuity test from the IDM connector and they all get 2.7 ohms (it was an older multimeter so not sure if being .1 under the 2.8-3.6 range is bad).
What I did next is use the uvch external pigtail to test the injectors. I plugged the extra pig tail into the uvch and then the ends of the wires into the plug of the upper harness. Afterwards, I would swap a different injector wire (on the pigtail) to the #6 injector wire (on the upper harness). Whatever injector that would go to #6 would fire correctly. So I know that the injectors themselves are fine. I am suspecting the wiring harnesses (upper/lower) but the continuity test would say otherwise. We also do not get any fault codes except for the EBP occasionally (waiting for a new one). I am lost on what to test or look at next.
Ford 6.0L Power Stroke Diesel :: Difference Between Injector Harness?
Is there a difference between the two harness #'s here besides the first number:
3C3z9d930aa
4C3z9d930aa
Are they the same part? Is one for a different model truck than the other?

I have a 04 F30 4x4 with a sick 6.0 power stroke. It has 230k on the mileage and ran good. I was driving at speed when she started missing like it had lost an injector and loosing power. The RPM's dropped under 1000 so I had to pull over off the highway. When i pulled over and put it in park it shutoff. Tried several times to get to start but after 10 minutes it started up. I drove about 2 miles and it started the same process. This went on 2 more times before I was able to finally limp home the 40 miles.
It never shut off again but ran very poorly. I put a new valve in and when I tried to start it just mad a pound clunking/clacking noise. The repair shop put a starter in it because it had stopped engaging and was going to ruin the fly wheel. I looked at it and it was eaten up pretty bad from trying to get the engine to turn over. So now all it will do is a single clunk and will not turn over. He says it could be a bad injector that flooded a cylinder or blown up in the bottom end. He did take serpentine off and still no go.
Ford 6.0L Power Stroke Diesel :: Glow Plug Light Came On - Lost Power - No Injector Cycle
Ok yesterday while driving my truck the glow plug light came on couple times and lost power but the light would turn off and power came back. It has done this before and it was the injector harness grounding out on the engine. I replaced that last time. I checked over the knew one and did not see any chaffing on the harness.
Now this morning I go outside to start it and I can hear my fuel pump and vacuum pump but injectors wouldn't cycle. It has also done this before but I could never figure out why. Last time I tore into it checking through my wiring harness and couldn't find anything. When I put it back together it started fine.
Ford 7.3L Power Stroke (1999-2003) :: Lost Power While Driving And Won't Start Back Up

My 99 E350 with 7.3 power stroke quickly lost power while on the highway today, bogged down and died. I couldn't get it restarted so had to have it towed home. I tried getting it started at home but it just pumps out white smoke out the exhaust. I got it to fire and run for a minute on a mixture of starting fluid and wd40 but wont stay running. Some background info, I checked oil and it was low but still registered at very tip of dipstick so I topped off oil level and still no start unless I give it a mixture of starting fluid and wd40. Batteries are good and cranking fast. Truck has 355,000 miles but very little blow by and prior to this had plenty of power and didn't have to use the block heater to start it thru the winter even when the temps dropped down to 12 degrees in January.
One thing I did have an issue with this past year was an intermittent cutting out while driving where the engine would instantly shut off but as soon as I tapped accelerator pedal it would start running again like nothing happened, wouldn't even last two seconds and it was running again just like shutting off the key and turning it back on and when it would do that the "Wait to start" light would come on and gauges would drop like key was off but again it all went back normal as soon as I hit a bump or tapped the accelerator pedal and it never lasted more than a second or two and never had to pull over, just tap the pedal or hit a bump and engine would kick in and run fine so not sure if that's related to whats going on now or not.
Ford 7.3L Power Stroke (1999-2003) :: Lost Power Steering / Refill Reservoir?
I lost a hose in the driver side front wheel well this morning while pulling RV to a campground. By the time I got there and got the RV disconnected, I lost all power steering. I reconnected the hose using a zip tie and have a friend bringing me fluid to refill reservoir.
Is my pump toast now? Can I refill the reservoir and prime the lines and be good to go?

Moving my worldly goods from California to Oklahoma in a rented 26' box truck with my wife following in our '02 F350 loaded to the gills with my lathe, mill, air compressor, weld and assorted machinery. Just west of Deming NM it started to blow lots of white smoke and down on power. Some rattling noises from the engine when throttled up & won't reach 3000RPM.
Had it towed to an impound yard for storage. Plan on sending a flat bed to pick it up when we get to Tulsa.
Any experience with a tilt back trailer capable of loading & transporting this truck that weighs around 17,000 pounds? My plan is to continue on to Tulsa & make arrangements from there.
