Ok so heres my situation, was driving home from work. Nothing crazy just crusing around 3000rpms in 4th gear still in vaccum. All the sudden the car completely shuts off and all the lights light up on the dash. I pulled the car to the side and tried turning the engine over. Nothing, absolutely no ignition. The engine turns over fine and doesnt make any noise thats out of place, it just doesn't start . I noticed the check engine light no longer lights up before start up, test mode does not work nor does it cycle the rad. fans and fuel pump when I connect the green connector. The fuel pump also doesn't come on when I turn the key to the on position in regular mode. This is on a 2002 WRX with stock boost, has a aem intake, and 2.5" catless turbo back exhaust. I also drove it in heavy rain for the first time since Ive owned it today so maybe that could have something to do with it? Just need help trying to diagnose my problem, I do have a VAG COM cable that reads and logs the ecu but can no way modify it, could I possibly use that to diagnose if the ECU is bad or not, any help will be appreciated I need to get to work! thanks!
