RE: Starting/Fuel Mileage prob

If you have a fuel pressure tester you hook it up to the test port on the inj. rail. Start the truck and record the pressure , then turn off truck and see what the pressure does. If it drops significantly in 5 minutes , start it up again and let the pressure go back up, turn it off and quickly pinch off the supply hose and see what the pressure does then.
