I got a lot of help about two months ago when my ECM, and alternator and battery, failed. After about two months from the initial replacement, Cardone rebult ECM was installed, while driving down the road, the truck died. Determined no injector action, no fuel pump action and no communication with ECM through OBD. Got another Cardone rebuilt ECM, lasted about 20 minutes, just idling in front of house and died. Got another , now has done the same thing. Parts store, after the third ECM, says "must be a problem with the truck". I have spoken with a friend who is Ford knowledgeable and he has never had this problem, never had something else on Rangers bring down ECM, but has experiance with bad rebuilt ECMs from Cardone. I don't want to blame Cardone, I just want to get my truck reliable again. Any thoughts? I have thoroughly checked grounds at battery and at ECM, and looked all over for signs of trouble. I would very much appreciate any ideas,
Thank You,
Tony
