1997 f150 5.4 ecu swap?
New to the forum seen a lot of ecu problems/fixes but nothing to the effect that I'm having.. I just swapped my ecu with one from an expedition same year /motor/ tranny and now my truck will start and run for literally 2 seconds and turn off like I shut the key off. Any ideas? Does the ecu need to be flashed or reprogrammed? Has this happened to anyone else?
