alright guys, all test are done. Not a wiring issue, not the pcm. Just not getting signal to the ICM or the injectors so i am back to the OPTI. Does anyone know what to look for inside the opti because i am about to take it apart.

See if you can find somewhere to get the opti tested with an oscilloscope. I think it needs to be on the car though.

Got a spare opti laying around? Plug it in to the opti harness, key ON and give it a spin. You should hear injectors click and get some spark.

Formula96

the only spare opti i have is the one that just came off of it, it makes its own clicks....

and i still can't get thepartsladi to return my emails

Still wouln't hurt, just for the sake of comparison.

Formula96

the reason i replaced in the first place was a no start no spark situation, i didn't do the noid test though.

So maybe your problem is not the opti if you still have the no start/no spark test after the new opti was installed.

I'm assuming all of the fuses checked out?

Formula96

all fuses were checked, the only thing left that it can be is a bad opti, all wiring passed the test, pcm was swapped, coil is new, havn't replaced the ICM because of no signal going to it in the first place.

It has got to be a lemon opti...

o and i know the old opti was the original fault because i can hear pieces of it clicking around...

Did you ohm out all the wires connecting the opti to the PCM?

I doubt that a NIB Delphi opti would be a dud.

Formula96

yes, all good

Possible bad PCM ground?

Formula96

new progress, same result, changed the opti for anouther NIB Delphi and same result, i have heard about this pcm ground but have not found it yet, anyone know exactly where to look for it?

I'd check the ignition switch honestly

PCM ground

Formula96

all 4 PCM grounds are good.

what would i check?

Formula96

i think i have found a solution...

now i just have to come up w/ $1500
I guess i could sell a brand new opti and brand new MSD coil for $300...

Formula96

bump for fresh ideas (excluding EFI Connection changeover, i don't have $1500 dollors )

Ok status report:

Symptoms: No spark, no injector pulse

Replaced opti (2) - so problem is not the opti
Replaced opti harness
Swapped PCM's - no change
Checked fuses
Checked grounds

What year PCM did you swap in to test it?
Did you check the fuses visually or did you check them for continuity with your DVM?

Did you test the PCM power as well as ground? I want you to be sure that the PCM is actually on.

Formula96

96 PCM swapped in, checked all fuses w/ dvom continuity and voltage KOEO, i did not check power to pcm, gives me something to do tonight...

THANKS, you have been a big help
