    Hey, Recently picked up a VR V6. Dual fuel (not running on gas so far)

    The problem is, Most of the time it wont start, it will just crank and not fire.

    Sometimes it will start by its self, then once its turned off it goes back to just cranking.

    Starts every time after spraying something flammable into the throttle body.

    Once its started it will drive fine, idles fine, has power (as much as any other buick lol)

    It doesn't seem to have an injector pulse while cranking, but does once its running.

    The coil packs where replaced before i go the car, so has the map sensor.
    Today i replaced the CAS and still no luck.

    Took the ignition barrel surround apart, and the security ring is making contact with the key fine.

    Every time it needs to be started i have to lock and unlock whilst sitting in the car to turn the security off.

    Also the fuel pump constantly primes whenever the ign is switched to acc or ign on.

    And while driving the batt light is constantly on. (apparently the alt has been tested and all fine)

    I want to try and sort the starting issue out first, Any help would be great.

    Thank you

    Alt was no good.

    Fuel pump was hard wired to gas/petrol switch.

    Bad Gas wiring/relay was cutting the injectors off.

    Sorted.
