P0261 code
Hi all. the last couple days the truck has been a hard start in the morning. about 28 deg F. I thought the glow plugs were getting weak or a couple of them were out.
Hooked up my AE and pulled codes, one of them was P0261 # 1 inj.
Truck is fully warmed up and is running fine.
Did a koer glow plug test and it came back ok.
power balance looks good now. Probly looked different when I finally got it started this morning. Took 3 cranks to get her goin and it sounded like **** till it got a bit warmer.
Any thoughts??

ok just to note I had the block heater plugged in all night as the temp is 26 deg f
I disconnected the glow plug wire from batt
koeo: ficm 47.5, batt volt 12.5
cranked over batt volt 11.57, truck started right away, the ficm might have gon down a volt during cranking??
with engine running ficm 46 to 47.5
One more thing is I never got the p0261 code thismorning, yesterday when I got the code the truck was cold, not plugged in.

Hi All. Ok id did a re test thismorning with the engine cold, Not plugged in temp is 30 deg f
KOEO ficm 47 v, batt 12.5V
Cranked engine and started FICM dropped to 40v ( or maybe lower since my AE will only read no lower then 40)
Let it idle for 5 min FICM went between 40v and 44v ant the last few seconds before I shut it down it reached 46v
I guess I need a new FICM
Any thoughts Please??

WatsonR, I have ran 15/40 non-syn sense new. I have had good success with non syn oil. at 240K I did all my inj seals, stand pipes and dummy's, oil rail seals, and havnt had a issue with anything HPOP related. change oil every 6-7K religiously
I do run 0w/40 in my old 7.3DI though

Well the FICM needs love!
How is your charging system health? Pull the Alt and batteries and head to your local box store and have all 3 tested! You might be surprised that you find issues there! 99% of the time the FICM dies because of the charging system.
#1 injector is easy peasey to do! My first injector was #5! That was a gem!
Oil change interval is a bit long! These things like fresh oil around 5k. 5w-40 is a nice addition to the engine. Run a round of Hot Shot diesel treatment with an oil change. It will get all the crude out of your engine.
