I know it isn't much, but it is all I had at the moment. It is my vehicle
and it died Friday while negotiating a traffic circle at low speed. When I
glanced at my fuel feed pressure guage on the pillar, it was at 0. There was
no check engine light. Turning the key on and off did not cycle the pump as
usual. No engine light. It did start after two tries and ran, but still no
pressure on the guage and no engine light . I drove 3 miles to the dealer at
low speed without difficulties and no engine light. Phone call today from
the dealer stated the error code from his DRB3. That's all I know and that's
not much, but I'm not there. It is the stock pump and there is 34K miles on
the truck. Never did install the FAS.
Okay. Well, I think you know the answer here... your lift pump's dead...
probably burned out the motor. The CP3 is capable of sucking it's own fuel
(as it does in the Duramax application), but that lift pump's a big ol'
restriction, so I'm surprised it even ran at all. Fortunately, the CP3's a
whole lot tougher than the VP44, so I'm sure it's fine. You're just going
to need a new lift pump, which should hopefully be covered under warranty
(unless they try and duck out of a legitimate warranty repair because of the
aftermarket stuff you've got). And, if they do the repair (either under
warranty or not - but I would STRONGLY recommend doing it yourself if they
won't warranty it, and you don't feel like fighting them for it - they'll
wind up charging you 2-3 times what a FASS would cost you), they're going to
change you over to the in-tank pump. Now, the good news about that is, it
retains your stock fuel filter/fuel heater, and makes the installation of an
aftermarket pump that much easier, since you'll already have the bulkhead
fitting on the fuel filter canister (in place of the old stock lift pump
that used to be bolted there).
Glad to hear it. Looks like your dealer is capable of applying common
sense. $100 is more than worth it to get it back running - and like I said,
makes the switch to an aftermarket pump, while retaining the factory
filter/heater, all that much easier :)
