I just replaced the ICM after the original one failed to create a spark. I replaced it with a used one only to have the replacment ICM burn out a week later. Does anyone have a clue as to what could possibly cause two ICM's to fail in a row? I don't want to keep replacing it every week.

harness could be bad. it did it on mine about twice.

You don't happen to know what was wrong with the harness do you? Shorting out?

y8's don't have a valve cover ground. Could a bad ground cause the ICM to fry itself? Maybe I should replace my ground wires and clean the contact points.

I swear, if I put another one in there and it burns up again, I'm gunna be pissed.

there was a loose wire on the harness sliding outta the ecu and shorting it out.
fried the ecu into a limp mode and burned the ignitor twice. even burned out the coil..

i would check near the ecu for anything outta wack, rusted, etc.

What conversion harness for the ECU are you using?

You need a OBD1 to OBD2B ECU conversion harness. Then you should be fine with the OBD1 dizzy.
