Default my car wont start

thoughts my car wont start, after driving in heavy rains and on and off flooded roads for 25 minuits. it would fire up anytime i wanted last night because i left again after the rain stopped. but today my car just cranks over and over. it started twice and the rpms jumped up an down then died it did not help if i held the gas on i also think i saw some smoke in my rearveiw mirror when it started. i checked the oil and it didnt look to have water in it so i dont think it sucked any up the intake (anyways the intake is in the fenderwell on a metal plate with the horn seperating it from the wheel) and i removed the wires on the coilpack to see if they were dry and they were so what else?

First thing you need to do is check for spark. If no spark we can start looking at the ignition system. If you have spark then we check fuel system I suspect you have no spark

If you have an old spark plug, pick a wire and plug the wire in to that plug. Then lay the plug on a ground and have someone crank the engine. Right now I suspect you have no spark. Things under the hood that can cause no spark is a bad ICM, or grounded ignition harness. You mentioned a lot of rain. I would start by removing all the coils, then lift the ICM off and clean up the bottom. Then clean the tabs and put the coils back on. Be careful, the bolts can strip easy, so just snug them up.

Confused. You found no spark but have you corrected the problem?

Hmm, you will need a stethoscope to listen. Could be a exhaust leak, or a stuck lifter. If a stuck lifter you can pull the plugs and inspect them. The cylinder with the bad lifter may look different. Can you tell which side of the engine the sound is on?
