if it runs good after it starts without bogging any, it needs injectors. the factory injectors will leak down when the engine isnt running, and when you are trying to start it, they have air in them.to see if this is the problem, hook up your fuel pressure guage up, crank her up. you should have at least 55 psi when running. kill the engine and watch to see how long it takes for the pressure to drop off. if it drops down more than 10 psi within say 3 minutes, you have a leaky injector. i replace all the leaking stockers with the bosch injectors from and they really wake these trucks up big time. good luck with it, later, brian
