    Injectors not firing.

    I just swapped in a low miles M42 and now i cant get it running. Fuel pump is running, has fuel pressure, I pulled the fuel rail out and cranked the motor and they didnt squirt a drop. I have a spare set of injectors, but I doubt all 4 would be stuck shut. I think it's an electrical issue. I double checked every connection and all the wiring is hooked up and correct (I believe). The motor came from a running car that i parted almost a year ago and was installed with the original engine harness in place. Anyone have any leads to help in the troubleshooting process?

      How would i go about checking that? Wouldn't the coils not fire if this were the case?

          Turns out I had the fuel lines (feed/return) switched. New motor runs great now!
