E30 325eS -- spark on all 6, injectors only firing on 1, 2, and 3... odd?
I have an 86' 325eS that I just swapped a spare motor into from an 85' 325e. C-101 was block to circle, so I just pinned it and spliced it to the car, it fires right up for the most part, but is only running on cylinders 1, 2 and 3.
I checked fuel pressure at 30 PSI which is pretty close to 2bar, should be sufficient. the car has spark on all 6, I listened through a long screw driver and heard injectors 1, 2 and 3 pulsing but 4, 5 and 6 were quiet.
anyone know if they run a common ground or something? I must have missed a wire when swapping the motors.
motor ran excellent in the car I pulled it from, so I'm assuming its not a problem of the harness or injectors... have tried two 027 ECUs as well just to make sure it wasnt a bad batch trigger.
