Help, I drove through deep water...

I didn't think it was that deep, but I got a wave breaking over the hood of my 1995 Cutlass Ciera. It did not stall, and I continued on my for another 6 miles. After about the first or second mile, it started running rough, coughing and sputtering. When I shut it off I was unable to restart it.
It has been more than two weeks, and I still can't get it going. I dried out the coil packs, replaced one, and changed the spark plugs (four of the six were cracked.) I am getting a spark. The engine cranks, but never even tries to catch. Does anyone know how to troubleshoot this to find out exactly what is wrong?

I would say thier's still water in the plug-ins and your ECU/PCM, which if I'm not mistaken is in the fender well.

Check all the sensors too.


If you ever drive through water like that again,
let it run as long as possible so it'll have a chance to dry things out from the engines heat.

Wire drier might help :dunno:

Good Luck
