thanks hbh lots of things to check, how bout the no pcm com.

 

What are you using to scan teh PCM?

 

acetron obd2 scanner

 

Try a differenct scanner. Could easily be a scanner issue.

 

also tryed a lap top with correct software. was doing tests from the link u sent me and no injector pulse, is it the opto spark or will that work with no com. with pcm

 

Continue with the testing. no comm doesn't always mean that there will be a drivability issue. I would however think about checking teh ign, PCM and PCM batt fuses...

 

Mine was acting similar to this a while back and it ended up being a couple of legs broke loose on the sockets that I soldered to the boards in the ecm. Actually, mine would idle but not rev, then it got to where it wouldn't start. I figured it out by accidentally bumping the ecm while under the hood. Everytime I bumped it it would run different or start/not start. Could be yer problem since it's a reman. Oh yeah, I also had no com during all this.

 

hbh thanks. computer was not flashed ,some people say car should start with no computer at all or unflashed. i cant see how when the injector wires go rite to computer. and if computer is not flashed, its like having a computer with no windows,usless. sent mine out to have it flashed teck said it was wrong part he said its 94 95 gm #88961150

 

Remaned PCM's will come with the most current programing available. It's possible that you did get teh wrong one however. Generaly there are about 3 diff part numbers that will come up and then needs to be narrowed down with the factory serial number.

 

hbh thanks it turns out last owner had it set up obd1 thats y no pcm com., and the opta spark was the problem. installed reman opta car starts will not idle, if i keep it running about 1500 rpm as soon as it gets hot it shuts down and will not restart till it cools down ?
