    Hi, I swapped my old 5.0 engine out for a good second hand one! (hopefully) anyway car was running when drivin in but now I have swapped engine it won’t run and if it does it won’t rev at all! Things I have replaced and swapped with old engine is new fuel pump new filter swapped distributors and coils swapped leads and cap swapped fuel pressure reg and throttle bodies cleaned all earths and checked timing and vacuum lines! Anyone got any ideas

    Today I did the hair pin trick and only code twelve which I think means no faults.

    12 is no faults.
    Umm it's got to be something simple. The sensor loop is reading.
    How old is the fuel?

    Sounds like you received a dodgy injector? Was it genuine?

    A mechanic said it could be the ECU but that’s fine and every plug and injector is getting power but it’s just the 4th injector it self that isn’t working I have tryed other ones but nothing and it’s getting 11v so plenty of power
