QuestionI have a 91 Pontiac Grand Am (Quad 4)I have replaced starter, alt, plug mod, and ECM. car runs good but now it keeps blowing the 10amp ECM fuse. When key is turned on fuse blows. How do I track down the short?
AnswerHi, start with the wire at the battery , then the starter, if you don't have any wires there that coulds be shorting out, then go to the alt and unplug it and see will blow the fuse, if it still blows the fuse then you will have to check the wires at the ecm,
