car died....help

ok, so last night i was driving, dropped it down a couple gears and jumped at my friend (prolly about 4k rpms) after i jumped, car died. fuel pump is priming, opti is getting power from coil, plugs are not getting power, is there anything besides the inside of the opti that could be responsable for this?

Re: car died....help

so what could i do to find out what it is? considering that the coil is sending spark to the opti, but the spark somehow gets lost between the opti and the plug, wouldnt it almost have to be the opti? any help would be appreciated...

Could be your ICM (Ignition Control Modual).. Or possibly your Coil. How old is it? Are you running an ignition system? It may have grounded out and shorted. Maybe your coil wire.. Anyhow, if you take the ICM to an auto parts store they can test it. That will eliminate one thing. Dont forget the dilectric grease for the back of it..

Ahh.. you are correct.. answering like 50 threads at once i got confused.. Didnt even realize.. Sounds like the opti in that case.. Did you check ALL your plug wires? Might have blown a fuse.. Maybe the opti connector came loose..
