I tried the paperclip trick, and I do not get any codes at all. The check engine light does not come on at all. I am guessing that the ECM is bad. From what I have read elsewhere, if the car dies with a tap test, ie slamming my car door, then the ECM is no good. Next question, I am going to try to pick up another model 1227727 ECM this week, do I need to keep the original PROM chip for the replacement ECM, or use the one that comes in it? Thanks!
