    You might have bad or old gas. Drain the gas tank then put two gallon of premium gas and the rest regular gas. If that doesn't work get gas tank cleaned. You can do this your self gust unconnectthe gas tank. make shore you have something to catch the gas that will spill out. then open the gas tank (most of the time they have bolts connecting them) then with a garden hose spray and scrub it clean. DO NOT use any house hold cleaner because they will stay and mess up the engen. let sun dry for about 4 hours are untill completly dry. reconect gas tank back to gether and reinstolit back on to truck. Mack shore to sythen the gas out before you take it off are you will be in a world of hurt. You will also need to have about 2 peaple help you do this and make shore to wair clothing that can be throne away, safty glasses, rubber gluves, and make shore no one smokes or has any thing that can make a spark or you will be BBQ. P.S. a breathing mast can never hurt but is not needed if no one has breathing broblems. I hope this helped. tell me if this soved your problem.

EGR valve is either faulty or most likely has a piece of carbon keeping it stuck open, causing your engine to run very rich (or lean I can't remember) and will not idle unless you keep your foot on the gas (and often the brake at the same time). Remove (you may need to replace gasket...easy to break) and see if you can dislodge the chunk or replace if you do not see any obstruction...

check your fuel pressure it should be 55-61 psi with key on engine off.It should have a fitting on the fuel rail to hook a gauge up to.If below specs replace pump.

ok, well as for the relay, yes there is one in your under hood fuse box....or inside the drivers door...but if you don't hear the pump, fear the worst, it may be dead.....happens ALOT.....check and change the relay, about $10, then if nothing, time for a new pump.

Intermittent fuel-flow problem


Been having the same problem. Ended up replacing the grey wire from the fuel pump relay to the fuel pump. The grey wire leaves the relay and then branches in two. One wire goes to the ECM to tell it the fuel pump has power. The other goes to the fuel pump.
