NO START! PLEASE HELP!

[7.3_pwr_strokin]

1999 7.3L wont start. The truck will crank all day...but will never fire. Banks is throwing a ICPO ERR code. Looked that up and it says on the internet that that means the output from the ICP sensor is not right. Made sure all the connections of the harness were good. Asked a Diesel Tech at the Ford Dealership and he said it could be a million things but seemed to be most worried about the IDM. Injection Driver Module. I have no idea. Took the plastic cap off the filter and the fuel bowl was full. Checked the oil reservoir right beside the fuel filter and the oil level was a little low may 1.5 inches below the top. Please help me out. Im not sure at all what it is.

as far as i know, a bad ICP sensor won't cause it to not start. good idea to replace anyway, a common problem with the 7.3L engine. have you had the CPS changed? if not, replace that, a couple bucks at the dealer.....

What code?? Could be HPOP failure, injector O-rings, IPR

try to unplug the icp and start it.could very well be the idm.

any blown fuses? fuel bowl heater is sometimes a problem.

[7.3_pwr_strokin]

Unplugged ICP...no start same thing. Starting to think is is indeed the IDM. Any tests to tell? Instructions for the replacement? I sure as Hell am no gonna pay Ford $1200 to replace. HAHAHA

Also, NO blown fuses...

are you seeing the tach move while cranking?

[7.3_pwr_strokin]

While cranking...The only tach that moves is the fuel level from Full to Empty. Nothing else moves.

[Highwaywrench]

your tach should jump a bit when cranking, change the CPS
