And still runs at 1500 if you unplug IAC?

Dave...what commands the IAC? You're the electrical wizard.

Shmed, I found a thread on the other board that sounds a lot like your problem. Swap the ECM with a known good one. There's a driver in the ECM that has something to do with the IAC...you may have smoked it. This came from John Spina...and he's one of the best.

I had a TPS issue with my car a few years back...and I had smoked something in the ECM.

It sounds like it is starting on the fuel pump prime circuit and the pump is not running after the key goes from start to the run position?

Kevin, he says it will run if he unplugs the maf or the iac...so that seems to suggest it will run on the limp home mode....Brad may well be right that it is an ecm problem...only strange thing is that it will run on either...but, maybe it is going to the calpac and ignoring the ecm?

A lot of broken parts does not make you a racer; it makes you a slow learner.
