Ok, so my car is only running on 4cyls now. I have found out coil pack 1/4 is not making any spark. Even with new coil pack installed. So i removed all 3 coil packs and put a led light on each prong that the coil packs sit on on the ICM. All show power when cranking the engine. What is wrong? Since only top 2 coils work after engine starts.

also i put the mulitmeter on the male prongs of each injector and they all read the same. So those are fine. (thought it might have been a faulty injector when i first started diagnosing, i also changed all the spark plugs)

If the coil is still not firing even after a new one, the ICM is bad.

ok, figured, i will get a new one tomorrow and try it
also i have a tiny fuel leak on the rear fuel connection on the fuel rail. Is it easier to replace the o rings in the black connetor or just replace the connector?

*dang* it, ICM's aren't cheap

Nothing wrong with going used on an ICM.

I got an AfterMarket ICM and it works like a dream when mines went bad...

I got a new one for $177 after tax, 3 other places wanted between $251 and $351 before tax. It works now, but found a new problem to why my antifreeze has been vanishing. Found Here
