    Default Weak/Slow injector pulse

    Just got a 95 xj thats dual fuel and am putting it through rwc.
    It wont run on petrol, only lpg at the moment. Done alot of stuffing around and came to realise that the injectors are pulsing wayyyy to slow, only about once per second. Have tried clearing/resetting the ecu but still cant get the injectors to pulse quick enough to get the car to start on petrol.
    Any ideas????

    Probably the crank position sensor. That controls when the injectors pulse. A common problem
