2002 Chevrolet Silverado 1500 Question: not holding fuel pres.

Without being able to do tests its hard to guess, but I would Tee in a fuel pressure gauge crank over the engine watch the fuel pressure, switch off the engine it should hold fuel pressure for a period of time, if it drops immediately I would pinch of the return line after the fuel rail/fuel pressure regulator and repeat the test see if it now holds fuel pressure. If it does the fuel pressure regulator may be bleeding of pressure, if the fuel pressure still drops look for a leaking injector but this would show up in a big cloud of black smog on start up, bad fuel mileage and fouling of the spark plugs.
