Does 3rd gen. have lift pump problem?

[gbraden]

At 16,000 miles, I have had no problems with my 2003 HO DC. For the past four months I have had very little internet access. Thus during that time I rarely was on the TDR site and don't know what has/has not been recent subjects of discussion.

I have been wondering if the 3rd generation trucks have a lift pump problem? If so, do you just replace it with another Dodge lift pump or is there an aftermarket pump that is better?

What about other problems, if any, that are showing up in the 3rd generation trucks.

Hopefully I'll find out that there are no known 3rd gen. problems, but I doubt it.

Thanks for bringing me up-to-date.

I've not heard of any plagueing problems. The lifts pumps have been the topic of much discussion but not due to failure as much as their inability to hold pressure up as fuel demand is increased with fueling boxes, injectors, etc.

They have replaced the pump twice on our EMS truck. Dealer claims long periods of idling and low lubricity in the fuel. No problems on my personal vehicle however.

If your concerned about the lift pump, order an 05, I understand that it has been replaced with an in tank pump. Whether this is an improvement or not I'm sure will be a future topic of discussion.

14000k mine was replaced left me stranded in the bush. Ya i would say there is a problem a big problem,While mine was being replaced there was another 3 trucks getting thiers done. .

The lift pump design itself doesn't seem to be alot better than in 2002. Failures are still being reported, but as Scott said I think there have been more concerns with the lift pumps not being able to maintain pressure on modified engines than failures on stock trucks.

The big difference is that a lift pump failure doesn't mean a injection pump failure. In VP44 equipped trucks a failed lift pump often preceded a dead injection pump and even if the injection pump survived, it was likely damaged. I have yet to hear of a CP3 common rail pump in a 3rd gen requiring replacement due to a failed or weak lift pump.

Bottom line: The $200. 00 lift pump may still fail, but I don't stay awake at night worrying about damage or reduced life span to my $2500. 00 injection pump.

I would suggest that lift pump changes in '05 indicate that the '03-'04. 5 set up still has issues.

ps. There is another current thread in this forum in which I identified common 3rd gen complaints/issues.

We purchased 4 2003 dually's

3 of have had pumps replaced so far, the last was just out of warrenty and it cost about $650 and took almost two weeks to get the back ordered part.

I'd say there is a problem with the ones that came stock, the ones they've been replacing em with are supposedly better.

And if ya think replacing the current LP located under the HOOD is a pain - wait 'til ya gotta drop the fuel tank to do the job - especially out in the wilderness!



As far as failed LP's not affecting/damaging the injection pumps - possibly true - but owners should continue to be sensitive to our diesel fuel low-lubricity problems - it causes premature pump wear in the later pumps just as it did in the older stuff...

Good point Gary.

Wouldn't it be nice to put ALL this fuel deliver issue solidly BEHIND us, and just DRIVE the damn trucks...
