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.

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 ?
