Well just got done replacing UVCH pigtails and valve cover gaskets..and now it won't start...key on and get wait to start light /engine light..changed CPS ..no change...getting 68PSI fuel pressure..I have E-fueled it. Hpop res. is full. Both fuel tanks are full...Unplugged the IPR ..no change...Any body know what your suppose to have voltage/ohm wise at the UVCH ends.. Injectors are fairly new..Tach moves when cranking Auto ingenuity shows about 160 rpm while cranking..HPOP jump up aprox.1500psi when cranking the engine...any ideas??Tryed swapping in my spare IDM..It has a swamps IDM in it..Want to check if i'm getting voltage/ The right ohms in the right wires on the UVCH pigtails in the morn...so any help is appreciated!!!:frown2::dunno:
Um, the engine won't run without the IPR, so reconnect it at least.
Injectors run at 100VDC, but it's pulsed, so you'll never get a reliable reading with a digital meter. First thing to do is continuity check the wires from the IDM connector to the UVCH connectors.
Did you happen to check IPR duty cycle on AE while cranking?
How strong are the batteries? 160 RPM while cranking is a bit on the low side.
Found a plug un plugged.....still no start ohm'ed out all the glow plugs and injectors all good ohm wise...Tomarrow un do all the wires I fixed and check them all again...(
Took the swamps one out and swapped in the spare... and nothing??? still have My ideas that its an Idm or a PCM... your thoughts...:smile2:
Maybe there is hope for the Lady running again....Hope so She is so comphy!!!
Kinda funny how this is going...Ran the spare while i was waiting for the Original IDM to the truck sent as a core to swamps...and after getting the swamps back It has been in the back seat since?
just put a reman. idm in and still no start!:frown2: But now when i hook up AI it will hook up with the computer but all the tests and sensors won't come up ???? If the computer lost KAM memory some how how would you go about getting it tested or reflashed????
just put in a new gear reduction starter !! Cranks fast at 200rpm ....but still no start no white smoke out the tail pipe???:frown2: been a month since it's run!!!:crying:
The IDM will shut down an entire bank if there is a issue with one injector in that bank. Double check all the wiring and UVCH on that side. Ohm out the solenoids and look for shorts to ground etc...
