M20 electrical help Please!!!!

[Luis325]

Need some help guys. E30 with m20 is running fine and all of the sudden it jus shuts off.
Then when you go to restart its like it has a dead battery. No crank.
Do it a few times and it cranks starts and shuts off a few times. Then just turns on like nothing after a while????
Driving me crazy.
Changed new main realy and fuel pump relay.
I looked around today and found 2 stripped cables
One in the main plug a black and green wire and another one in the iddle control valve plug.
Could that be the problem?





Covered it up. This is the green black wire.
Anyone knows what its for?? I think its 15?

The black/green goes from the starter to the unloaded relays. The red/white goes to the main relay.

Why not fix them and see if the problem goes away? I mean, those wires need to be fixed regardless, so...

[Luis325]

Yeap i fixed them up today. Just wanted some opinions on what could cause this.
Tomorrow im driving 1 hour each way to a big bmw event i hope i fixed it...

My friends car had problems like that in the harness. After two weeks of banging our heads troubleshooting and fixing wires we pulled a farm fresh engine harness out of the junkyard and replaced it. Takes about an hour maybe 2 and no more issues haha. Not trying to discourage you but changing the engine harness is easy.b

This is the type of problems you see when the fuses are replaced with larger than specified. OP, you're going to have to remove the covering insulation and inspect as much as the harness as you can and make repairs.
