I picked up my 135 and its new fuel pump today. The car has been flawless so far. Apparently the ecu readout is fault-free now. I feel as if the car is getting better fuel delivery than it was before this all happened, but that could very well just be psychological -- probably is.

I learned from an old E36 board posting that the DME (computer) needs time to take an accurate air/temp reading. If you interupt that process (starting the car and quickly cutting it off) it doesn't take an accurate measurment. When you do give the DME and Mass Air Flow sensor time to communicate, all is well.
Just thinking that maybe your problem is actually Air Sensor related and not fuel pump related.
Does anyone know if you can do the self diagnostic test with the 1 series?
