1273 & 1280 on 2001 Excursion

[Chris Farley]

I have a friend who has a 2001 Powerstroke Excursion. It started running really rough, like it is missing, more so when cold. When it warms up, it runs better, but not like it should. He changed the fuel filter, and there was a brown waxy substance on the old one. Changing the fuel filter made no difference in drivability. He had the local diesel shop pull the codes:
1273 and 1280
I have plenty of experience with archaic, underpowered GM diesels, but am new to Fords. I suppose, that it would help us out if I knew a few more of the accronyms. What does ICP stand for? (And I dont want any answers that involve Violent J. and Shaggy).
What does IPR stand for?

icp---injector control pressure
ipr---injector pressure regulator


p1280 most likely is the icp sensor on front of left head 3 wire conector

p1273 sounds like drivers side injector at the front cyl. 2 short harness unhooked under valve cover , need to take drivers side valve cover off and reconnect they make a clip to install under tab to prevent from happening again

WOW! Thanks for that quick response!
Do you think that the brown crap in the fuel filter doesnt have anything to with the codes?

[SCUFFY828]

will not cause codes , may just need to clean out filter housing good , and see if it comes back

[Chris Farley]

Are you saying that the crap in the fitler and the troulble codes are separate issues?
Would it change your mind if I told you that we just recently started running biodiesel in this truck?

[Chris Farley]

Scuffy828,
You were right on the money! The "local diesel mechanic" says he found a loose connection under the passenger side valve cover!
Thank you!

[SCUFFY828]

i love it when a plan comes together

and by the way , if you are running good biodiesel it shouldnt hurt anything , i might change filters more often , do you know what the percentage of mix your running

[Chris Farley]

This last tankfull was close to 100%. My friend ran his tank almost empty, then filled up with B100.

[SCUFFY828]

to be able to get into details , i cant , but we are told here that ford recommends only 5 % biodiesel and fuel mix , thats what all the ambulances around here are doing with no problems, whatever it is that your running is bought from a reliable source and not just backyard mix it should be fine
