Re: No spark
Sounds like your ICM took a dump, of course it could be the CKPS, or wiring in between. Get your ICM tested first, that is a good start.

Re: No spark
Have you got spark on all six? You can have the ICM tested at any national auto parts store. How about the fuel pump, is it running when you first turn the ignition on? Have you checked fuel pressure?

Re: No spark
Pull one of the plugs, and use it for a spark tester on all six. Look for bright blue spark. Never pull the wires off of the coils; that energy has to go somewhere and it usually fires into the ICM which can cause permanent damage!

Re: No spark
ok got the car started got good sparks, but know it stays idle at 1500rpm and 2000rpms it wont go down. Theres a part next to the mass air flow sensor that if i move it the idle goes down then up, but i dont know the parts name i will see if i can put a pic...

Re: No spark
That is your idle air control (IAC) and how did you move it while it was installed & the engine running?
