    Hi folks, I just replace my fuel pump after it failed 10days ago,
    Pump replacement went well But I now seem to have problems with the engine management,
    DTC p0335 Crank position sensor A Circuit Malfunction, And
    DTC P0339 Crank position sensor A CKT Intermittent,

    Since the car sat so long I had to boost start the car And eventually just went and got a new battery, I have also cleared DTC P0339 But not been able to clear DTC P0335,
    The Car starts and drives But the rpm's will stutter at 2400rpm,

    Any help on this condition would be much appreciated

    Welcome! Check to make sure all fuel lines are free of cracks. Just throwing a stone since you replaced the pump.

    Update! I have a wiring issue in the harness, On the engine harness just behind the Oil filler there's a hard connection of about 5 or 6 blue wires all soldered together into 1 blue and 1 green wire, I've only been able to give it a pinch with my fingers But it has got it running good And I cleared the codes, il need to get into it closer and do a proper repair
