lift pump question

777 Views 8 Replies 8 Participants Last post by  speedntriple
I just did the APPS adjustment and reset a few days ago. I'm a little concerned now that the lift pump doesn't run when I turn the key to the on position prior to starting. It always did prior to the APPS change. With the key on prior to start, the pressure says it's at about 1 psi. The fuel pressure sits at about 13 at an idle so the pump must be working. I didn't the two were tied together is this a coincindence? Is it OK?

Thanks

the pump usually just bumps over until you release the key after the engien starts. As long as you are holding pressure once the engine is running, don't sweat it.

Ops
We'll see how it goes I guess. Just seemed odd that something changed after the APPS adjustment.

just bump the starter over, not enough to start...you should hear the lift pump start running, if not you've got a problem
Mine only runs if i bump the starter,not when i just turn the key on.
Need Help

I recently purchased and 02 3500 Dodge. It has approx 85k miles on it as of now. It has a hesitation or lull in it at around 45 to 50 mph. At this speed occasionally when i go to accelerate i get no response from the engine. I have to let out of it repeatedly or stomp it until it downshifts. This truck has had several Banks Power systems added also. I also feel the truck is not as strong as it should be. Any ideas would be helpful.

tpickitt if you are still reading these, i would check your lift pump i was having simular problems with my 01. i have dual lift pumps and the first one went out restricting the fuel and it ran like .if i were to do it over i would have got a fass because stock lift pumps are $186 and i purchased two. if you aren,t gettin any code its got to be something with your fuel.
