Any problems with these computers. Have a no spark situation and she throw a lot of codes from fuel pump to ignition and you name it:W These computers are very difficult to get a hand on. Anyone know one who sells?

A good rule of thumb when multiple codes are present is to disconnect the battery to clear them then see which ones return. If there are still several codes indicated, begin troubleshooting with the lowest numbered code first, as each one is diagnosed and repaired, clear again and recheck before proceeding or condemning the ECM.
The 92 and 93 ECM's can be difficult to locate, but there are several companies that can rebuild them. Links to a couple here:

Welcome to Gmautocomputers

Thank you.

It is a bit out of my hands for the time being. Had the car towed to a nearby garage and they work on it. I just supply parts as they go on replacing. Coil replaced, they work on the opti/waterpump/plug wires and plugs now. I thinc the ignition module will arrive on thursday and then that will be replaced to. I did plan to rebuild the ignition to MSD this winter so all parts where in my garage. The only thing i needed was the module which i ordered today.

Never heard about problems with the ECM but time will show.
