New reman long block was installed in the truck. The 2nd start of the motor resulted in 1391 code, although the engine ran great. Both cam and crank sensors were replaced and ECM was reset. Engine still ran great and again, on the 2nd start, the check engine light came on and returned the 1391 code. I am at a loss as to where to go next. Any clues?
have the same problem?
