So i have a 1990 mitsubishi eclipse gs 2.0l and have no spark. i have done everthing possible to my knowledge to find a problem. Power transistor is good, coil test good for continuity,power, and ground, camshaft position sensor replaced, had no injector pulse so i thought it was ecu, bought new one 300.00!! still no spark or injector pulse. I tested the harnesses from the ecu, #'s 109,54,55,4 all had continuity and weren't supposed? can anyone please help??
