Engine/Transmission (1998.5 - 2002) I think I fried my VP44

Where did you buy your first 2 injection pumps from?

Ok, this is getting better by the min... So, I replaced the Fuel filter (just to eliminate some possible problems). While doing so I noticed that the bowl was completely dry. I bumped the starter and it did not fill. I pulled the line on the FASS (suction side) and put my thumb over it. I'm feeling no suction what so ever.... I would think I should feel something right? I'm guessing that the FASS failed and grenaded the VP... But my fuel pressure gauge is still showing 16 PSI. I have it hooked to the low pressure side of the VP. It is reading 16 now with no fuel in the system..... The perfect storm??? loosing the entire fuel system at once? I don't get it. Does FASS have a rebuild kit? the motor is definitely running so it should be just the pump part that is toast.

I ran my truck out of fuel the other day would not fire but pump was running I ended up pulling bleed plug on filter and filling filter full of power service hit the key again and it primed right up and started

My 1st pump came from Liberator Performance in Carlisle Pa. Back in July 2010 after have driven up there for a car show, I had been having problems w/ the trk & was thinking the transmission needed help, so I had a friend bring his fancy snap on scanner down & ended up with a dead injector pump. While there they talked me into the Fass fuel pump, hey it's only money. I don't know who supplied the pump but the it was a rebuild unit.
The 2nd injector pump came from Chason Deisel Service in Garner Nc. Closer to home but still a bear to tow my truck on my trailer & with as buddy's 250 series gmc van. The Fass was sent back for rebuilding, the shop installed the low pressure light & a Vulcan draw straw and another rebuilt injector pump with all the current upgrades.
I know the cause this 2nd time was from a tank of bad fuel, what they drained out smelt like paint thinner & looked like peanut oil.

I did a quick check last night & still not getting any codes at the dash, batteries are ok but I should start thinking about getting new ones as they are 8 yrs old. Can't hear the Fass pump come on to prime the other pump. Didn't see any broken fuel lines or leaks.

I think I'm just going to wait till the weekend when I can start doing some testing.

Need to figure out why the FASS isn't running first before you condemn the injection pump. Check any fuses related to the FASS. Also check for voltage at the plug on the vehicle side of the harness when you bump the key. The FASS should be under warranty.

Been slowly working on this,bought two new battery's after I ran them down while fiddling with the beast. Found the problem with the fass pump/ twofold. Pinhole leak in the water separator filter, other one somebody pulled the fuse for the pump. Talked with shop owner that did the inspection,none of his guys remember taking a fuse out.
I put in a new one & the pump started right away. I guess I know the injector pump is toast.

New question ; who should I buy a pump from? I talked w/ the shop that did the last one, install cost is up to $800. Now.
They can get another rebuilt injector pump for $ 1600 std 1 year warranty
Are the Blue Chip ones really worth the extra cost?

Yes, please list what you've done to condemn the VP.
As for injection pumps and who and where to go, talk to the shop and find out what they are using for fpcm (computer). Used? Reman? New? Is $1600 for the pump alone? I think you'll find most shops that call there fpcm's "new" are really reman boards. One of the reasons Chips pumps are more expensive are his are built using new updated fpcm's, the same ones required by Fed Ex years ago when the early ISBs were used in the FL trucks. They were different than the ones Dodge used and had so many problems with. They've got a less than 2% failure rate on their pumps. I read of lots of complaints on their prices but never hear of failures or problems with their pumps, so IMO it is worth doing it once and being done.

Also, I would suggest replacing the pump on your own to save yourself some money. If you do buy a pump through one of the online diesel vendors, they will warranty the pump whether you or a shop installs it. $800 is a lot of cheddar for a simple 2-3 hour job. Maybe 4 if its your first time. Chip will loan the pump gear removal tool for free, waive the core fee (provided you send in your old pump in a timely manner) and has a good write up on swapping the pump out with some time saving tips.
