Hi guys,
I have been tracking down a cold start issue I have since a little while (car has a hard time starting after sitting for 5+ hours) and last night, I think I might have found something.
I have tested the fuel pressure of the M3 (E36).
When car is at idle, it's at 45psi, which seems fine.
When I shut down the car, it's at 42psi, which also seems fine.
Although, after letting the car sit over night (about 10 hours), the pressure went down to 28psi. Do you guys think it's a significant enough drop to indicate a fuel injector leak?
Thanks!
