AE86 check engine light help
Posted: Fri Nov 15, 2013 4:43 pm
So for the last 6 months or so my car has been running fine no issues, aside from my passenger headlight no going down.
Anyway last night I drove home from work parked my car with the headlights off but in the up/open position like I normally do. This morning when I went to start my car it just cranked but would not turn over.
I tried putting down my headlights and they wouldn't go down nor would they turn on, also the high beams wouldn't go on either and the high beam indicator on the dash did not light up.
So I tested the battery and it read 12.5v and all my other lights/radio/signals worked so i ruled out the battery being dead. I checked the 15a efi fuse and the 10a engine fuse in the engine bay and they were fine but I replaced them just to be sure.
I did notice that the check engine light does not illuminate when the car is in the on position and If i recall correctly that means there's no power going to the ecu? So what wires would I have to check/trace to see if thats the issue?
Also its pretty strange that this would randomly happen during the night from just sitting in my garage
