L200 , starts on the key - as soon as you let the key back the engine stops?

    It could mean the throttle body is jammed open, or the engine is running on oil, if its a diesel. This is called a runaway engine and can cause serious damage to the engine.

    Could be a broken wire that cuts off the signal to the injectors when the key is released, get a computer diagnostic and that may sort it out

    Good luck.
