Are you sure the lift pump is running? Crack the fitting on top of the
filter canister that comes directly from the pump - see if you get fuel
there. If so, something's plugged downstream from there. If not, your lift
pump may be toast.
These lift pump are famous for failing. It is a poor design. The actual
design flaw is up for argument, but most agree there is a flaw. You probably
have a bad lift pump if you aren't getting any fuel. you might hear it
running, but it no pump.
Now for the warranty. You have a 5/100K warranty on it, but are probably
just out of warranty now. If so, you can get the lift pump from a Cummins
dealer cheaper than the Dodge dealer. You can get a Carter replacement from
some auto part stores, which is the same pump, but does not have the
Dodge/Cummins-specific connectors for the fuel lines and electrical
connections. You can go this route if you don't mind a little modification
of the fuel system. I just read about a guy who did this on
www.dieseltruckresource.com. He didn't have a dealer close by, either Dodge
or Cummins, but had a Summit, who carried the Carter version, close by, so
he modified the fuel system a little, and is happy.
I think it's very unlikely that the lift pump would decide to shit the exact
moment he decided to change the fuel filter. Even if the lift pump did go
out he would have most likely seen symptoms before now. The fact that the OP
put up two messages within one hour and then hasn't replied to any other
posts since then leads me to believe that he got it running.
That is when most find out that the lift pump is not working. When the lift
pump fails the injector pump will pull the fuel, and all appears okay. When
you change the filter then it becomes real apparent the lift pump has gone
south and your injector pump is right behind.
Quit making sense dammit, it's annoying! ;^)
I thought the lack of power symptoms would be very noticeable but after a
bit of research I discovered several people claimed not to notice any power
difference until after changing a failed pump.
Guess it is time to hijack this thread anyway. Been working so damn much ot
haven't had time to do much of anything but sleep when I'm home. Am going to
try to get out on the quad this afternoon for a couple of hours. Have some
coyotes that have been forced in close due to all the development that are
becoming a pia. Maybe I will find where they are hanging out. Kind of a
screwed up deal, building way too much, non of it commercial, all
residential. Tax's are going to go through the roof.
Ordered the pond should be here in 6 weeks. Weighs a bunch, close to 7K.
Guess we will see just how strong the deck is. Figured on it when we built
it, so should be okay.
So Mr. Hathcock, how's the shoot'n been doing?
What are you paying for gas and diesel out there?
7K?? That must me without you, right?? <G> Coyote are considered
varmints around here, I haven't got any but I know of several guys that have
plinked a few. I just get the hogs and a few coons that get in the barn.
Next meet is next Sunday, I'll be sure to let you know. Who knows, I may get
Depends on the weekend and the mood of the gas co. Gas is anywhere from
$1.80 to $2.20 for 87 octane and oil stays fairly constant $2.15-$2.20.
From what I have learned the lift pump provides more fuel than is required
to run the engine. The excess fuel cools the inj pump. No lift pump and the
engine seems fine until the lack of cooling takes it's toll on the inj pump,
then as it fails the performance declines.
If you didn't fill the canister housing with fuel before putting it together
it may take several tries to get fuel to the banjo fitting. The procedure is
explained fairly well here:
