    Check fuel pump fuse and relay, if they are good you have to verify power at the pump, keep in mind the pump only runs a few second then shuts off till the engine is running...

    Thanks for your response. I have checked both relay and fuse and have checked power to the pump and all check good it seems to have something to do with the anti theft like the shock sensor just to the left of the column has not told the Bcm or the PCM that it is nota theft to let the injectors and pump run. many things I've read say that the shock sensor is supposed to tell them that the signal or voltage is correct to unlock the pump and injectors. I'm not sure what to do everything else is working fine. I have removed dash and shot wires from the pump to the fuse box and to the engine fuse panel and still am at a loss. engine cranks lights work security light is out and still no fuel from the pump or the injectors
