    Crank no spark

    After taking my family to dinner in the marauder and returning home and a two hr rest the car only cranks over, fuel pumps running with pressure, checked all fuses and diodes and all have checked out. What am I missing?

    Sounds like the Crank Position Sensor is bad or unplugged
    Did you VERIFY there is no spark?

    Are you sure the fuel pump is running during crank? Does the PCM have power? Did you check the fuses?
