Help. Had to get a tow. Fuel Pump? VP44?
Shop looks at it monday, just getting ideas of what to expect.
Truck starts fine, idles fine but the minute you give it any fuel it starts to choke out. sounds like a bad miss. No smoke. just a miss.
now it only idles for about 30 seconds and then starts to lope and miss a little. I also am not hearing the buzz i used to hear at start up.
I am guessing maybe my liftpump is out?
If so i know they are prone to going out. what should i put in it? should i go with a factory replacement, aftermarket, add an airdog or fass while im in there?

Its your lift pump. Its not pumping the fuel like its supposed to. Its like running your truck out of fuel. With a VP44 pump that is a bad thing. they tend to go out if you run them out or the lift pump craps out on you. If you change the lift pump and it starts after bleeding injectors warm it up normal operating temp. Turn off truck wait a few mins and start back up if don't start change injection pump. There is a valve of some sort inside the pump that the fuel lubs it with out the fuel it just trashes the pump.
