1988 astro no fuel

Dude..
I don't know..
I am stumped.... and bent out of shape.
I a year I have towed this thing 8 times for the same problem.
I can't find it...
My mechanic can't find it.
But... I am thinking the oil pressure sensor is the only item I haven't changed... So I'm gonna pick one up tomorrow... just for kicks.

Eventually I will find it...
Too many new parts for me not to... there is hardly anything left to replace. I believe I am working on the Process of Elimination theory.

sounds like time to shoot this car, I'm definitely not going to tow my car 8 times, I found a site to buy the ecm if nothing else works for about 230 & 75 back after you send in your core

I am still having this problem, but now after checking my fire with a timing light. I seem to not have fire or fuel. Just changed a fuel pump relay this morning, picked up yesterday before I read this site. The van started twice & died both times after 10-15 minutes. Is there a sensor that would stop the fuel & fire or is this the computer? Trying to decide if I should just tow it in or replace something??

I bought a Node Light and checked for a signal to the injectors, No signal. I went to the parts store to pick up a new computer, $89.00 and they don't come with the Prom's! I think it is one or the other. I have reset the two plugs to the ECM (computer), I also reset the two proms in the computer. Still no signal to the injectors.

Well I found my problem! It was the Ignition Module, I checked the Ignition Module for voltage, the book tells me with the engine at idle (all I can do is crank it over) pin B of the 4 wire plug go's to the PCM pin 10 and is called Referance pin should have 5 volts, and I did not have any reading for volts or ohms. I did do a bunch of other trouble shooting: I pulled appart the large connector located under the hood right side to see if there was corosion in there, checked the ground wires located on the left upper side of the bell housing, I checked for chafed wires, I checked for 12 volts at the injecrors. I jumpered from pin D16 of the PCM ( injector signal position) to the NODE light to make sure that the wire is good still no signal. I ran 12 volts to one side of the injector and grounded the other side it shoots gas out of the injector.

I would have thought with that failing that you would have had no spark rather than no fuel spray. Hmmm. Learn something new every day...
