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.

98 Civic EX

 

make sure the ground on the valve cover is connected... Had 2 go before I figured it out!!

 

harness could be bad. it did it on mine about twice.
800 dealer fix lol... i couldn't figure it out.

 

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.

 

...i had a loose wire in the dizzy that kept getting contact and then fell off...dam thing fried my ecu...try to look in the dist and see if anything is outa place...

 

I’m having this problem I keep replacing my dizzy . After replacing dizzy car fires rite up turn it off car won’t turn back on lose spark what can my problem be I’m lost my grounds look good for the most part ecu is good . It’s a 2000ek lx with a obd1z6 engine I tried both OBD2b dizzy & a obd1 dizzy same problem . Have stock OBD2b ecu currently

 

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.
