    You will need to find out what is missing when your truck won't start, spark or fuel and go from there. It may be time for some help from a qualified technician to get to the cause of your problem. There are to many different things that could cause your stalling problem for me to even begin to make a guess.

    If the fuel pressure is correct and you have spark at the plugs and the engine still won't start then I would try spraying starting fluid in the throttle body. Don't spray while cranking or the engine can backfire through the throttle body. If the engine will start and run for a short time with the starting fluid then I would suspect that there is a problem with the injector signal from the PCM.
