geo metro injector
If I understand correctly, the engine control module (ECM) needs to provide a ground to the injector on my 91, 5 spd, Geo Metro.. Tried the ECM and distributer in another car, and both work. The car will run if the injector is grounded to the frame with a test lite, so the injector is working. It just isn't getting a ground from the ECM. Is the problem in the wireing, or are there other possibilities? How can I identify, at the ECM, which wire grounds the injector? Thanks. Gerry
