Hello everyone, please help

[Kaiguy]

Hey fellow diesel lovers, I am a new member but long time lurker..
I drive a 2001 f350 cclb dally and I am having some issues, any help or input would be greatly appreciated..
I parked the truck one night about ten days ago and haven't been able to get it started since.. Before parking it was running fine, no power loss or stalling or rough idle, nothing. It cranks over fine but will not fire. Everything seems to be working normal, rpm gauge moves when cranking, oil pressure goes up, fuel pump is working, ect.. Truck has brand new batteries, starter, fuel bowl and filter, cps was done about 9 months ago.. Hpop res. is full, wts light cycles normally, fuel bowl is full and pressurized with no leaks and was purged of air.. All fuses have been checked and are good, but not sure how to check the relays that are located in fuse box under the hood.. Truck will not even fire with ether.. It has a php six position tuner, 5 inch exhaust, and cold air intake, otherwise stock... Any help would be appreciated, thanks in advance..

I moved your thread to get it more exposure to your issue.

Welcome to the ORG, BTW!!

Thank you,
Btw, I also tried unplugging the ipr and icp, both had no effect..

See if you can find anyone close by that has a copy of Auto Enginuity with the Ford expanded software module. It should show what might be wrong.

I am located in the Poconos, right by the jersey pa border on i80, eaststroudsburg...
Can anyone tell me if a bad GPR could cause this problem?
And are both the brown relays on top the motor gpr's?
I have a volt meter but not really to knowledgable on using it, if anyone could tell me how to test which relay or both that would help..
Thanks

i'd change out the CPS. You'd want to carry a spare anyway for if/when they go bad. Your symptoms sure has the signs of a bad one.

[Kaiguy]

Would the rpm gauge still move when cranking if the cps was bad?

Cncrestoration, thanks I will let you know how I make out...
I just can't afford to get it towed to another shop that has no idea what they are doing... Between a full tranny rebuild and torque converter, and all the other things I've done, I'm about 5grand deep in this thing over the last three months.. The wife is getting fed up, lol
