Car Forum / Dodge / Dodge Trucks / May 2008bad ECM?
Hi, My truck has no fuel and no spark. The ASD and fuel pump relays both tested good and have power at the connectors. The first time it wouldn't start for me, with key on the relays would rapidly click on/off while the check engine light flashed in sync with them ...the relays don't click anymore and the check engine light will not come on at all. I did verify that there was power and ground at the ECM harness (but I don't know which pins are supposed to be what). Is it likely that ECM itself has failed? If so, do they just fail on their own, or is there likely a short or something that will fry another one if I replace it? Thanks for any advice, Its a 1992 5.2L MPFI, around 225k miles > Hi, > [quoted text clipped - 10 lines] > Thanks for any advice, > Its a 1992 5.2L MPFI, around 225k miles Is the battery fully charged and are the connections good and clean at both ends?? >> Hi, >> [quoted text clipped - 13 lines] > Is the battery fully charged and are the connections good and clean at > both ends?? When the problem first developed battery was fully charged and cranked engine over with lots of vigor ...though it's a little weaker now after me messing with the truck. Replaced ECM with a remanufactured one and truck runs perfectly. > Hi, > [quoted text clipped - 10 lines] > Thanks for any advice, > Its a 1992 5.2L MPFI, around 225k miles |
