Hello all!
I'm writing this new thread because I'm totally stumped.
My truck is a 96 7.3 335K miles. 5spd 2wd
I've been reading other threads and changing parts for about 2 months now.
My truck takes about 10 seconds of cranking to start. I get the error that says ICP not detected during crank
Runs OK when cold. When I gets to normal operating temperature, it runs rough, low fuel pressure, no power at low rpms, have to Rev the engine to 1200 rpms for it to move. If I turn it off, it won't even start, I have to let it sit for a while for it to start again.
It has a new HPOP, ICP, IPR, FUEL PUMP(twice), valve cover gaskets and harness, injector o rings, oil rail crossover, oil reservoir is full, glow plugs and relay
When I unplug the ICP still no start.
Buzz test pass
Normal blowby
Here are some numbers
Warm engine
637 RPMS, ICP voltage 0.67, ICP pressure 405 psi, IPR duty 70.6 (why?.)
1100 RPMS, ICP voltage 1.19, ICP pressure 1013 psi, IPR duty 53.1
Cold engine
620 RPMS, ICP voltage 0.64, ICP pressure 405 psi, IPR duty 41
1100 RPMS, ICP voltage 0.94, ICP pressure 810 psi, IPR duty 28
The HPOP, ICP and IPR, are from Pensacola Diesel. Are they good? All the other parts are from dieselorings.com
What now??
Thank you!!
