Hey, I'm trying to get some help on my e34 m50 swap into my 91 e30 318is. Using a 91 m50nv with a white label 402dme e34 auto harness.
I have a no spark and no fuel issue but I can crank the engine. so far I've checked:
DME pin:
26 constant 12v
54 constant 12v(I think this is suppose to be swtiched though?)
56 switched 12v
65 switched 12v(for the e34 auto harness)
55 grounded
6 grounded
34 grounded
I have checked Crank Sensor at 522ohms at pins 67 + 68
I have been able to jump the fuel pump and it works
I have 12v at the injectors.
Something I noticed that is weird is there is constant 12v at the MAF.
I have a new CPS on order, but in the mean time is there anything else I can look at it?
Does it have to be a red or silve 402 ecu? or does it not matter on a 402.
