VP44 metering valve maybe? - Diesel Forum

My '99 24Valve Ram is trying to die when you stop, But when I get it started after giving it a shot of either it will run with all the power that its always had. With that I dont think the Injector pump is gone yet but I cant keep starting it with either or I know there will be more expensive consequences later for doing that. Ive replaced the lift pump earlier this year but it wasn't dying when I stopped. Right now I'm thinking that maybe just the metering valve is sticking and that the injector pump is still o.k.?

There is no metering valve in a VP44- all electronic controls. Have the truck scanned for codes.

Cycle the key on and off three times, leaving it in the run position on the third round. I'm pretty sure that on a '99 the odometer will display any codes stored. The odometer will say P ECU, ------, done, P PCU, ------, done. Give that a try and let us know what you find.

Do you have a way of reading the fuel pressure? If you don't have a gauge on there I would highly recommend getting one.

Air leaks? A small air leak somewhere in the system will make it hard to start.

Alright I tried cycling the key and nothing happend. I dont have a fuel pressure gauge but I could get one at harbor frieght or somewhere on monday.Once I get it started it will run till I kill it and then It wont start on its own again. when its sitting ther Idling it kinda dips a little too. My IDI did this once too but whatever it was It passed and went another 60,000 miles before I had to have the pump on it rebuilt.
