ok its probably been answered plenty of rimes but in my search iv found nothing i just got a 97 f250 with the 7.3 ran fantastic then just died while driving now the po had just put a cps on it the month b4 so i dont think that should have went again so i renderd the gp inoperable and shot it with either and it did absolutely nothing now i am used to mechanical diesels but it should hahe done at least somthing .

Maybe you didn't use enough?


Just because the PO said the CPS was replaced, doesn't mean it was a good one.

I will change the cps this weekend but if that's a no go what other sensor can cause this issue

If it won't do anything, check the fuse for the fuel filter heater, the heater shorts out, blows the fuse, no power to the PCM and other things, will crank but no start. It's a 30 amp fuse, may be #22. Disconnect the plug for it on the fuel bowl. If the heater is shot here is the replacement form IH dealer. Lost the pic on Webshots. Anyhow IH has them $26.

Another thing is the IPR on the back of the hpop, down under the FPR.

 

[gsxjay]

IPR what is that and its use

 

[79jasper]

Injector pressure Regulator.
It controls the oil pressure to the injectors.

You can try unplugging it during a no start condition. But it's a pain to get to. It's common for the nut to fall off.

 

[gsxjay]

if i unplug it and it starts then its fouled up or what dose unplugging do for the issue sorry for the questions just want to know what i am dealing with

 

[79jasper]

Basically that it's bad. IIRC.
