What were the symptoms when it came to you?

I take offence to the "troublesome" comment... Change the oil in them and they will run forever...

 

the wife was backing out of the driveway, went from rev to 2nd, and she says it died like she turned off the key.

definitely had a short in the gp relay, changed it and didn't blow #22 fuse again, and still once again had a wait to start light.

is it possible, being that they are both linked through #22, that a bad gp relay could fry the pcm? do I need to put down the pipe for a comment like that? or could a bad pcm fry a gp relay? The only psd tech manual I have is the electrical/vacuum manual.

I have one of those sick feelings that I have spent a whole lot of money on parts that I didn't need, and can't take back; all while searching for and missing a rather simple solution.

 

Unplug the fuel bowl heater, check the fuses again.

Need some way to scan it, first to see if the PCM is getting fired up and second to see what the ICP pressures are.

 

icp pressures are near 0, I have a 0 - 5000 psi hydraulic pressure gauge setup with a boss o-ring fitting that I put together just for this type of test. As for the pcm, all of the outputs that are to sensors directly linked between the pcm and the high pressure oil system that I am aware of seem to check out. but it is dificult without further equipment to see if the pcm is sending all of this info back to the idm.

Also I can say with near 100% certainty that it was the gp relay that was popping the fuse. changed the fuse...blew the fuse...disconnected the control wire from pcm to gpr and changed the fuse... no more blown fuse...changed gpr... still no blown fuse.

1 small battle won

 

going to try checking dead head pressure off of the hpop tomorrow when I am off work, and see what that gets me, if I can't get any pressure off of the hpop itself, I can swap out the ipr from my other one. If I don't get any pressure, me and someon'e gonna have some words...

no pressure from the "new" hpop, going to try swapping an ipr, and see from there, might stilll have some words.

... stupid stupid stupid... fuel bowl heater...

 

99.9% of the time that is what it is....

98.9% of the time people tell me I am wrong.

Glad you got it fixed.
