Was fine now no start?

And just to make sure, you tested it with everything plugged in the way its supposed to be and you poked through the wire insulation to check for the 1.2VAC on pin B?

Since you are getting glow cycle assuming you are also getting an SES light with ign on. Meaning PCM is getting all the right power. I would try to access the PCM with a scanner with the ign on. If these things are all good then I'd say PCM is probably fine, but they can go bad, especially if exposed to a lot of heat.

Attached is a file with the signals that go the PMD. You can test that the PCM is sending a signal to the PMD. With PMD unplugged you can verify that there is power at pin D, and the fuel inject signals from the PCM.

Yes I get glow cycle and SES when key is turned on.
With scan tool connected I get power from the PCM, no codes are stored and I have a crank signal.

I have powe and ground to the PMD so then I geuss I will spend my weekend tearing the wiring harness apart... :(
 
Well just had a buddy show up with his trailer to pull it home for me and he says whats it doin?? so I go to show him and the ****in thing starts right up..... I geuss that confirms wiring damage?
 
intermittent No WTS light = no PCM power = ignition issue, thats something different than saturn's problem because he gets the WTS and SES lights.

I changed the ignition switch and haven't had another problem yet. I'd have to check posts to see if it's been a month.
We usually have a no start about once a month ir every time I'm about to give the Suburban back to my daughter.
Any more ideas on what to check on my 96?
