Ford 7.3L Power Stroke (1999-2003) :: 1271 Injector Code - High Side To Low Side Open Cylinder 1
I've got a 1271 code and I can't seem to make it go away. Code definition is "High side to Low side open Cyl 1". The truck runs fine, no rough idle, no excessive smoke of any color, just the damn CEL light stays on. I check the UVCH and all the injectors ohm in at 2.7 ohms. I've already done the updated clips under the covers. I run all the buzz tests and KOEO/ KOER tests and all appears OK. My AE won't do a Cyl contribution test. All the injector data shows all 0.00. I know its not that perfect. "high to low open", does that mean I've lost a ground? If so where?

New to diesel trucks and wondered if this recurring code is a serious problem. I clear DTC and truck will run fine. Might stay off for 2 days or 2 months and same code comes back. Truck seems to run just fine even with service light on.

So I got an IDM code and then after running AE buzz test got a P1273 (#3 cylinder high low open).
Ohm'd out the 42 Pin - got 3 across the board. Only test 42 pin from valve cover to injectors.
Double checked UVHC
Swapped solenionds
Swapped injectors
Did ford wiggle test.
Ran Injector buzz between all those steps and still get P1273.
What's the next step? Ohm from IDM to 42pin? May actually be a bad IDM?
Ford 7.3L Power Stroke (1999-2003) :: IDM Failure Code And High Side Open Bank 1 And 2
Today I just installed a brand new IDM and after running the Injector Buzz Test test, I received codes: P1298 Injector Drive Module Failure, P1293 Injector High Side Open - Bank 1, and P1294 Injector High Side Open - Bank 2. How a new IDM could throw these codes?
When running the KOEO test I received codes P0605 Injector Control Module Read Only Memory (ROM) Error, P1298, P1293, & P1294.
My engine is still missing but the engine is running a heck of a lot better after replacing the IDM and injector 8 has a rotational velocity of about 3%
Ford 7.3L Power Stroke (1999-2003) :: Code P1271 - #1 Injector High - Low Side Open
Getting DTC Code P1271 - #1 Injector High -> Low Side Open.
The code tends to show up more during cold weather start up. Using AE-AutoEngenuity KOEO - Buzz Test returns the P1271 error
Troubleshooting performed:
- 42-Pin Connector @ Driver Side Valve Cover
- 9-pin VCH on Passenger side
- IDM Module under driver side wheel well
- All of these are testing within the 2.8 - 3.2 Ohm range
- (Used the GB Reman. Tech Bulletin 103) - TB 103: 1994-03 Ford 7.3L IDM Replacement & Diagnostics)
I was going to replace the solenoid, however, with the above readings I'm not convinced it's the solenoid. Before I tear into the valve covers I was looking for some add'l thoughts from the forum. Could it be the IDM ?....
Any add'l checks to perform using AE, or the IDM, other than replacing IDM.

Ford 7.3L Power Stroke (1999-2003) :: P0269 Cylinder 4 / P0284 Cylinder 8 Running A Little Rough
So I did a cylinder contribution test and a buzz test today. It buzzed evenly on all cylinders. Then when I did the cylinder contribution test I got these codes,
P0269 cylinder 4 contribution balance
P0284 cylinder 8 contribution balance
It has been running a little rough lately but not smoking. Seems to be chattering more than it was too. I did the FRx, HPx, CVDs and banjo bolt mods about 500 miles ago and it was a lot quieter and ran better. Just recently started running rough and a little louder. Could these injectors be bad? I did new injector O-rings about 800 miles ago. I ran the test with the engine cold and with it warmed up and got the codes both times. It seems to have a little bit of throttle flutter when holding it about half throttle while driving.
As far as I know the injectors haven't been replaced and they have 186K miles on them.

Ford 7.3L Power Stroke (1999-2003) :: Torque Pro And SES Light When Pulling Fault Codes
I have a 2001 F350 with a PCM labeled "PMT2".
The SES light is triggered every time I try and pull fault codes using Torque Pro. It has done this since I installed Torque Pro many months ago. Same thing happens in another local member's (2000) truck, although I don't know his PCM version.
I'm very comfortable with the Torque Pro settings that have been detailed in other Torque Pro threads. I have been careful to choose conservative settings, including trying debug mode. I have uninstalled and reinstalled Torque Pro to see if that solves the problem - which it does not.
Question: "PMT2" PCM been able to pull fault codes using Torque Pro without tripping the SES light?
I realize another variable may be my OBD2 Bluetooth device. As an aside, I have removed the AIH and would expect to see a fault code but Torque Pro reports no fault codes.

So when I bought the car, it had a check engine light. I had it checked it said cylinder 5 misfire. I assumed it was the glow plug so I bought it and replaced the glow plugs myself. Check engine light went away for about a day then came back on. Got it checked again and still said cylinder 5 misfire. This is my first diesel and I'm clueless as to what's wrong. Any way to check what's wrong myself?

Ford 7.3L Power Stroke (1999-2003) :: 2001 - Cylinder Missing Until Motor Warms Up
My feed truck (2001 ext cab 4x4 7.3 198k) had a cold starting issue I fixed with new gp relay. Now I noticed when it gets down below 30 degrees it has a cylinder miss until motor warms up. I don't doubt injectors are in my future. I was wondering though if that is common for worn injectors or if maybe something else has gone haywire and how long can I run it like that before something else tears up? after about 7-10 min the miss goes away and I don't notice it. I would like to get through the winter before messing with it or having injectors put in it...
