No start????

I have a 96 ford E-350 with a 7.3 powerstroke diesel and it started running real rough then it died i pulled the codes and it had a bad cam sensor and i replaced it and it still wont start and now its giving me a p0603 code witch is a ctrl mod kam error would this keep the van from running.

603 Won't keep it from running & the cam code could have been set by long crank...

Check your fuses, oil , batteries...Are you getting a WTS light ?

Any smoke?....

Make sure the connection is good at the cps and that it is installed all the way in.

The FP test port is located on the driver side of the fuel filter housing. It's a schrader valve (tire air valve). You can use a tire pressure gage but it gets messy and takes 2 people, one cranking the engine the other holding the gage. You should see at least 30psi while cranking.

Yes it can have something to do with it, as the oil temp sensor sends a signal to tell the GP's how long to stay on.

edit the pcm uses the oil temp signal to determine glow plug actuation length

With the out of range EOT. The GPR will not drop.
Unplug the heater and check fuses, and links at the gpr.
