Ok so my car keeps frying ignition modules, on my 3rd one know, and it also blows the ignition fuses and other fuses in the fuse panel under the hood. any one have this problem or could give me an idea of what the problem is. also it has been in a local shop and they just replaced the fuses, battery and module and said it was fixed.... I dont have the money to take it to the dealer. anyone that has ideas i am willing to try anything.........

 

Maybe a short in wiring.

Hey also I remember some people having problems with certain spark plugs killing the ICM. Have you changed them to something different?

 

they are the same as stock, just changed them after the last time replaced the ignition module

 

have they ever replaced ur fusebox? i had a short under mine.

the one in the engine bay

 

how much does that cost?

 

not sure, was done under warranty.

 

Hey...im on my second ignition module now...try changing the sparks. My dealership said that it can cause them to go...wich eventualy could lead to the igmod goin again... Also said that it could be a bad module. we'll see what happens though...mine went 2 in one month. One more month to go and we'll see what happens....keep us updated if you find out any more...

 

Does the 2.2 Have the ignition module that connects to all four plug or the singles.
Im asking this if maybe it is one paticular module that is going ,say #4 plug all the time.

If you changed the plugs and there is a higher than normal internal resistance it would draw more current and cause premature failure of the module.

Avoltage drop on the feed wire for the module due to a resistance in the circut could do it as well as a short that interupts the voltage (wire shorting to the head repeatedly).

Also check your voltage at the battery while the car is running should be around 14 to 15.5 volts dc.

 

also, if u have a large system the draw at startup might be putting a big strain on ur car. If u do have a system make sure cars electrical system is properly supported with thick wire and stiffening caps

 

no system on mine car...just stock sub which draws nothing. haha.....Come to think of it..i do remember the tech that worked on my car saying that their was a misfire with one of the plugs. but never said which one......

makes me wish i had a tuner or a gauge that would say if they were misfiring.

 

ur comp will record all misfires. If u had one it would show up on an obd2 scanner.


(if u go to Advance auto or some place like that they will let u use one for free)

 

the plugs were changed, but they were changed oem plugs, how do i check for a voltage drop in the feed wire, there are no wires exposed around the head.

the 2.2 has direct fire ignition just like the rest of the ecotecs....

 

my plugs were changed in mine as well...so hopefully that helps...found a OBD2 Scanner on ebay...3.25, 20 bucks shipping. haha may look into getting that just incase something happens again....;Originaladrian....what do u think?...worth getting one on of those or?...

 

yup there great, just make sure u get a decent one, some people have been saying that older model obd2 scanners are not working properly.

 

How do u tell whether it is a late model or not?

 

if you had a misfire you would throw a check engine light on.... late model means like a newer-ish car

 

think he originaladrian was talking about the older scanners...and ya...my check engine light was on...i'd just like to know which one is misfiring

 

you could pull coils individual n what ever one doesnt change the idle is prolly the one thats misfiring

 

its not the coil that is the problem, its the module...
