Is my Lift Pump dead??

[Smokin Joes 2500]

Im starting a new thread, about the same problem I mentioned in another thread, because I have new information.



The shop owner told me tonight, after an injector install, that they can not get any fuel up to the injector lines. It will just dribble out at best. Im thinkin LIFT PUMP???? Am I wrong/right??? I mentioned to him that I thought it was the LP and he said "a Duramax has a CP3 and no lift pump and it will still pull fuel up from the tank" I then told him a Dodge has an in tank LP that when bad will not let the CP3 "pull" fuel it will just not run. Am I right??? He was unaware of this :--) Is it possible with only 13,000 miles on it to have a bad lift pump??? He said he will check it out, I hope he does. Im guessing thats why they cant get fuel pressur is cause its broke and wont let any fuel by. He also said Dodge recomends changing the injector lines when changing injectors??? Have you heard of this??? He said they were like $20 bucks a piece... Said he wont install them unless absolutly necessary???

Sounds like something is clogged. Checked the fuel filter. I mean a few bad tanks of diesel could have clogged up some lines. Purge the engine, and see if you hear the pump turn on. Just purge her, don't turn her over. If you hear the pump, open the check valve and see what the flow is like. Sometimes this is what it takes to push some crap out of your lines. If pressure sucks, then try changing fuel filter. This is all of course if you do indeed hear your lp running when you bump start her. Unless your just that % of guys that gets a bad batch of mopar parts, I wouldn't think a lp would go bad that quick.

What do you mean by "check the valve" where is this valve?? I ordered a new LP in case, Ill take them a filter too.

It is a yellow lever under the fuel filter about halfway down from hood to ground.

Sounds like he's referring to the drain valve on the fuel filter.
