    CPS is bad or giving faulty reading, may be wiring, may be sensor itself.

    code P0320 stored.
    Tests/Procedures: 1. Check if the oil pump drive housing has rotated on the hold down clamp. If it has, replace the oil pump drive gear and housing.

    2. Scope the Crankshaft Position (CKP) sensor.

    3. Scope the Camshaft Position (CMP) sensor.
    Potential Causes: Camshaft Position Sensor (CMP)
    Crankshaft Position Sensor (CKP)
    Distributor Sync

    Sounds like the crank shaft position sensor! My moms went out and the XJ would not start just truned over and over.
