Okay, Car has been 100% reliable until a week ago I lightly sprayed off the engine bay. Car started missing a bit, and I immediately drove it to a friends to help him do some diagnosis on his NA-T that wasn't running right.

We removed, placed on his car, then put back on my car my Ignition Coil, Igniter, and ECU. We also blew down in the coil and igniter in case moisture there was causing the car to miss. Put my ECU, Coil, and Igniter back in, car fired up and ran perfect the whole way home. I let the car sit over the weekend, Monday morning it took forever to crank, then ran like absolutely **** (throwing a cel) the whole way to work and home... missing like crazy and what not.

The next day I pull the TB and all plug wires, lightly spray WD-40 in plug valley to displace water, then spray it out good with compressed air. Replaced all plug, car fired right up, rang great all day.

The next morning, the car takes forever to crank. I finally get it to fire, it runs perfect, pull out of driveway, car dies and will not crank again. Turns over fine, just won't start.

I leave the car, come home from work, car starts perfectly. I pull in driveway and put on another coil and igniter. Car starts perfect again, take it for a test drive, car dies a block from home and WILL NOT FIRE again. That was last night. I'm sure the car will crank when I get home enough to get it back to the house, but does anyone have ANY clue what to check next? Coil wire maybe?


Thanks in Advance!

check and see if the alt is good, check battery

Electrical system is fine. Got tons of juice for turning over the car and powering the audio/lights/accessories.

Alternator and power steering pump are also both brand new on the car.

Wow... well if it fired up and ran fine... how long did you let it idle/warm up for after spraying down? because it sounds like it can be electrical but with a newer alternator and the car starting after the first time it kinda rules it out not 100% but enough. Fuel might be the issue, when it turns off does it just die or does it choke up a bit and then turn off?

It just straight dies. Going down the road perfectly fine then.... nothin!

man it still sound like you have water or moisture lying in connectors or plugs. I have delt with it alot. You may have also loosed any connections when spraying the engine. I would say check all you vaccum lines and for moisture first. PM if you need anymore advice.

I've always been scared of doing that for the same reason. It might not be that. I would get the alternator checked cause just cause it's new doesn't mean it's good. Does it die while you are driving or do you drive it for a bit, stop and then crank it again and nothing?

So tonight as a last ditch effort to get it to crank (after I'd tried unplugging every connector in the engine bay to check for moisture), I hopped in the passenger seat and stomped my feet around under the footwell (where the ecu is). It fired right up. Apparently the plug didn't get plugged in all the way. It was late so I just drove it home. Gonna get under there and fix it tomorrow.
