    E30 help.

    I have a 1988 E30, it had an e in it and I switched it to an i. I got the right ecu and wire harness with the engine. It turns over fine and I have power to and from the coil and power to the injectors. New plug wires, cap and rotor but still no spark. Any ideas? I know there are 2 other computers under the dash could one of these cause this? And what are those two computers? One has a blue plug and the other has a connector like the ECU but you squeese the silver tabs togeather and pull for the connecter to come off. Please let me know.

    I checked the fuseable link in the trunk and it was broke so I jumped it with a wire to see if I could get any spark and still nothing. I checked the coil again for power, and I have power to the small and big wire but nothing to the middle one where the wire runs to the distributer. Should I have power running from there?

      Got it!!!! The Crank Possition Sensor was plugged in to the wrong plug. The plugs are the same and right next to each other but one is turned the other way around so it would make sense to be plugged in the way I had it but I guess not.
