Just for information, my M3 (which has stood for longer than I can remember) would not start, I drained all the old fuel off and put fresh in tank, but still no start. Would fire on easy start but not run.
Found pump in tank u/s so replaced both pumps to eliminate them, still no start.
Read on one forum about injectors sticking, remedy was to have engine turning over and tapping body of injectors, was bit apprehensive but gave it a whirl, hey presto as I tapped them each cylinder chimed in and now starting on the button.
I was thinking all doom and gloom scenarios about ecu etc (had replaced all relevant relays as well) but was simple fix but took about 6 weeks to eventually get it running!!

Can I get a bit more detail on this part of the process? I too have this issue every once in a while and have my car flatbedded to a local shop where they take apart the ECU and ground out the two prongs that connect with the injectors. Works every time, but your process seems MUCH easier (and cheaper). I'd appreciate more info.

Thank you!
