    That is correct and I still am, but you should know that Mike as I sold you your throttle bodies and you can always ring me for advice
    Mike how are you grounding the cable shielding (only ground one end otherwise you create a ground loop) and ground it as close to the ECU as possible

    Crank sensors are notoriously sensitive due to the nature of the sensor and frequency of the signal and can require a little attention, EMI in general can be frustrating but nothing to get all uptight about so before you go and start unloading your annoyance on the water pump, ashtray and other random items borrow my scope and look at the crank signal (I can help)


    BTW I'm only using this login because my normal (SKiddell) is messed up....admin can you sort

    I have not grounded the shielding cable yet but I will give it try.

    I have sort out my problem


    Ended up putting in a resistor across the 2 wires going into crank position plug at about 3" from the end and it works as it should with no interference from the electric water pump .

    What does that do Mike? Does it reduce the voltage to the sensor?

    I cancels out the noise interference from the electric water pump,
    It does change the signal slightly as the ecu guy told me it might be a bit more difficult to start in the winter

    it works like the condenser on the alternator to cut out feedback coming through your stereo as an example
