Archived She turns over but she does not fire

[bsweet]

I have a 99' 2500, quad, auto. I started the truck tonight it started fine drove 1/10 of a mile and it quit. The fuel guage reads a little better than 1/4 and according to the mileage on the trip there should be 8 or 9 gals in the tank.

I talked to the service manager at the local Dodge dealer and he said it might be a fuel shut off mod. ?

Any help would be appreciated.

Bump the starter, do you hear the LP running?



Have you checked your fuel pressure?



Have you checked for codes?



Could be some other things, but the #1 reason for Truck SDS (Sudden Death Syndrome) is the fuel system.



Do you have any performance modifications on your truck?

Service manager told me today it is a bad injector pump. Is this a common failure at 50,000 miles?

On a 1999? It has been seen before. Lift pump was probably dying for some time now and finally took the injector pump with it. Have them check the lift pump and fuel pressure test the truck at wide open throttle. It should not drop below 6 psi at wide open throttle. Low fuel pressure, or no fuel pressure, will cause the injector pump to die. If they put in a remanufactured or new injector pump and don't check fuel pressure, you'll be back in the shop before you know it. Also, just checking fuel pressure at idle, or revving the engine in the shop won't cut it. They have to tape the quage to the windshield and take it out on the road for a full throttle run to 70 mph. If that pressure drops too low, time for a warranty lift pump too.

There are lots of failures with the VP44 pumps when the lift pumps go. Some pumps can survive, some cannot. Some people see VP44 failure when they start to bomb and place more of a demand on the injector pump and the lift pump. Good thing it happened under warranty (and IT IS covered under warranty. )



BTW, don't trust the fuel gauge as they have been known to be wrong. Unless you already know that "E" is definitely "E"...

The VP44 gets its cooling and lubrication from the excess fuel. When the LPs go south they loose the extra fuel for cooling and lubrication which causes them to basically burn up. Now the P-pumps get all their cooling and lubrication from the engine oil so thats why they aren't effected as much by a bad LP.
