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.
