seb70 · 06-30-2009, 10:54 AM

my lift pump went out. Im curious if that will also damage my injector pump. I have heard that is a pretty pricey item. How will i know if i am going to have to replace inj. pump?

Yeap... A bad lift pump will KILL a VP44 in a short order...

This is why all of us will HIGHLY SUGGEST...

1. Get a fuel pressure gauge and ALWAY keep the pressure above 10 PSI.
2. Get a fuel system upgrade like FASS or AirDog soon.

Running a truck with loow to ZERO fuel pressure is like running a engine with a dead oil pump. The only thing that lubricates the VP44 is fuel so if you don't have enough fuel pressure/volume that VP44 is metal to metal contact with all internal parts...

I agree... You won't know when the injection pump goes until it does. The only way to check it is to have it bench tested. And yes they are price around $1050.00 for a stock SO pump.

SHort answer is Yes. Get a Raptor, AirDog or Fass on the truck asap. Generally, the above mentioned pumps don't fail, so I wouldn't say its essential to run a light or gauge with them...but it isnt a bad idea either.

IF (BIG IF) you catch a dying lift pump early enough, going to a good pump MAY save your VP44. The crappy thing is, it might last another 5 years or 5 miles. VP's will typically give some signs of failure before leaving you stranded. Hard starts hot, stumbling, lack of power and usually injection timing codes.l

As mentioned above, lubrication is key, so be sure that you are running some sort of additive, two-stroke oil or a little bio to help keep the pump happy.

Good luck!

I was driving down the hiway at 65mph. and the truck died ,got towed home the codes said it was a fuel problem. I sent it to the dealer and they called today ,and said my lift pump died and my inj. pump went with it

now to fix it they are charging me $3800. for the inj. pump and they said that the oem. lift pump is junk so for $800. they install the new replacement pump in the fuel tank

$2700. inj. pump installed
$ 800. replacement fuel pump
$ 300. trouble shot
_______________
$3800.

it will be done in 3 days I leave for my first vacation in 5 years in 2 weeks,

it just never ends

Sad but true... a $40 dollar fuel pressure gauge would of saved you the $3,800 bucks...

or buy a 1050 vp44 SO from any of our vendors, pay a normal shop labor rate to install it, buy a air-dog, fass, or raptor, a guage and be out the door for less than 2k

the427chevy · 07-01-2009, 03:55 AM

3800$ for the pump is rediculous, its what 3 hours to put in... you can get a pump from thorobred diesel for 1050$, free shipping, no core charge for 14 days and they pay to ship the core back.... i've done two pumps that way and haven't had any bad expierences.

He bring up a valid point... My shop hour books show the job to being 4 hours for Injection pump replacment.

They are definitely taking advantage of you. 300$ to trouble shoot,! at best 1 hour worth of labour, how long can it take to pull codes and check fuel pressure! and for what your paying for the factory intank you could buy a FASS or AD and pay someone to install it or do it your self and save a couple hundred dollars.and end up with a better proven pump!, 2700 installed, its criminal! but I guess its the way dealers operate, I feel for you. If you have any money left spring for a fuel pressure gauge, and it might help you down the road.
around here shop rate is around 105$ or better, how much is it in your neck of the woods?

Adding a bit more now... (Book hour rate)

VP44 pump replacement - 4.0 Hours
VP44 Diagnostics - 1.0 Hour
Lift pump replacement (Stock) - 0.7 Hours

So for a total of 5.7 hours the job is done... Now lets throw price of $90 a hour...

$90 x 5.7 = $513 for labor.
