Archived Major Problem II - need some advice

[lberch]

Have been having the identical problem that "Bigstick" had posted in the Engine & drivetrain section under "major Problem - need help".



Basically, since the the truck was new (June 2000) it has always started within 1/2 - 1 revolution. Last week it started to take 2 - 3 to more revolutions to fire. Finally this weekend it will not fire off at all unless you bleed air @ the injector lines. When you get it running it runs fine, no stumbles no misses no problems. Even bled it and ran it 45 min. and 20 mile with no problems. Bring in the garage and shut it off 10 sec and try a re-start and it will just crank and not fire.



In "Bigsticks" thread he had mentioned talking to Cummins mechs. and they were leaning toward a VP44 seal gone bad??



I even thought I was sucking air an have replaced the fuel line with a seperate new one and checked for air in a clear hose - nothing.



Any input would be appreciated before the dreaded call to the Dealer. Truck still under warranty @ 39,000 miles.

First,confirm the lift pump is working properly if at all,its liekly dead. if its OK,then id check the banjo's if ones loose it will suck air. Look at the banjos on the return side too,there is one at the rear of the cyl head. Anytime air gets in it will need to be primed. My guess is a lift pump ,and maybe a loose fitting.

Thanks Snowman, but the lift pump is giving me 13 - 14 @ idle and drops to 10 @ WOT. All banjo seals replaced w/new.

This is a strange problem. If I go through the trouble of bleeding @ injectors and get it started it will run with no problem indefinitely.



I will probably be talking with the dealer in the morning.

Just to let you know it was my VP-44 and they replaced it under warranty with the power wire tapped and the VOID sticker missing. Of course the truck was in stock form except for the lift and I was able to obatain a genuine Chrystler DRB II scan tool to clear my codes out. If they do replace your VP-44 make sure you get a silver one and not a black one b/c the black one is a mexican reman pump and the silver one is the new German pump. I wanted to tell Dodge so bad what was wrong with the truck but b/c of the chance of them finding out I know too much and void the warranty when they investigated I kept dumb and quiet it took them a week of diagnosing and phone calls to figure it out and 2 men from Germany representing Bosch came to look at it and called me while they were there. Just some advice.

Thanks Bigstick. Truck went to dealer Monday afternoon. Talked with them yesterday and they said that troubleshooting with STAR they have a VP44 on order. I also have an HO, do you know the P/N of the HO pump? I am worried that I will wind up with a non HO pump.



Thanks again,

hmmm well I would but my paperwork is in the truck which went back to the dealer yesterday due to a leaking steering box and my slave cylinder going out which was causing me to almost rearend people at stoplights. You kno when it rains it pours! I do know this the non HO pump is 1250 dollars and our HO pump is 3200 dollars.



If it has tits, wheels, or it floats, it is gonna give you problems... .
