I have searched and read over numerous no-start/bad ecu threads and still havn't got an answer. So heres my problem.....I had a brain fart and pulled the positive battery terminal while the engine was running to test the alternator, dumb i know, but i have done this numerous times on carburated vehicles with no problem. When i Pulled the Positive Battery Terminal my windshield wipers/Cooling Fans both came on and the engine rpms dropped. I blipped the throttle with my hand under the hood to keep it running as the engine speed increased so did the fan/wiper speed, i then quickly shut off the car.
Now i have a few problems. 1. The car will not start, i am not getting power to my ECU/S-AFC. 2.My windshield wipers are always on unless i pull the fuse (probably due to the voltage spike welding the points inside together) 3. Neither My HVAC Fan or Radio are getting power now.
Engine will still crank over but will not start. With Key in the Acc/On position power windows, Sunroof still work. Headlights/parklights, signal and brake lights still work.
I just found how to check the MFI Relay and i will be doing this tomorrow. Would a bad ecu or MFI Relay make the radio/HVAC have no power, and if not what should i look for to address these problems....Also i have checked, double checked and triple checked every fuse under the dash and under the hood....
