    Is the battery any good? Did all modules  communicate ? What were the codes? Any immobilizer codes? Did you load test your main body and chassis grounds to engine? Relative compression even? Cam timing ok? We need more information

    Tested the battery and its good only codes are p0335 this car is not equipped with a immobilizer I have done a compression test and checked timing they came back in between spec in have not done a load test on body grounds I'm just starting out on diagnosing no start conditions don't have much experience in that

    You are saying that you can communicate with the ECM with the key removed from the
    ignition?
    You are saying that with key off you read 6200 RPM's on the data link but show
    0RPM's cranking?
    Injectors 1 and 2 should have power in pin 1 of the connector,the yellow wire and
    injectors 3 and 4 should have power in the blue wire pin 1 key on engine off.

    It looks like the engine control relay provides the power for both cam sensors and the
    crank sensor, along with injectors and coils. Start there, make sure that you have 12
    volts in the power wires of those components with the key on and no volts with the key
    off. The ground and signal wires for the cam and crank sensors are seperate. The
    power wire is the only common denominator. That is where your problem most likely
    is.

    Hi again Kevin yellow wire shows ground when the key is on I was able to get it started by jumping the yellow wire and another wire going to the battery
