I have a 2004 Dodge Ram 2500 Cummins 24 Valve Turbo Diesel - running down the road it stops, I change the fuel filter and it runs eventually. Then we go through it again. Codes are P2509 and P0628. I am reading som much conflicting information, I do not know what to believe. Any ideas?

 

Well, the 0628 is easy, it is your lift pump, common on the 03-04.5's. Do you still have the canister mounted pump? They have a very high failure rate. If you do not know how to tell, I can show you.

The 2509 is an ECM code. Most of the time when I see ECM codes, the first thing I do is clean the batteries, main ground contact, and if they are the original batteries, I would have them tested. The batteries only have about a 5 year lifespan...

Welcome to the DTR.

 

Does this require the retrofit kit to relocate the fuel pump? The Dealer says according to my serial number no - What about FAAS or Air Dog

 

Yes. Both are good. I go with Air Dog, or you can go cheaper and go with the raptor.

What are your goals with the truck? Stock, or are you going to add performance mods?

 

Work - no perf mods

 

I'd go with a raptor then. Just a 100. Very easy to do, probably an hour. I would also recommend some gauges too.

I'm being kinda general with the info, if you want me to be specific about something, just ask.

 

Good Morning - I am relaying this to you from the driver - He said when the truck dies, and you unscrew the filter element, the cannister is only half full of fuel. On heavy equipment we have installed an auxilliary fuel pump to keep pressure on the line, and that's what he was thinking of doing here. You know 12V 2-3# inline - between the tank and the fuel filter. That and a new battery, as when you look at the gauge- it is charging low- Ideas,comments?

 

The stock pump is not a flow through design. When it dies, very little fuel gets through it.

Either get a raptor that has a conversion kit to remove the stock fuel pump and hook the line into the stock filter canister, or get an Air Dog and go straight to the CP3.

You're going to spend the money one way or an another trying to get fittings to make it work with a cheap pump. Just do it right the first time.

The batteries are only good for about 5 years on average. However, if he is seeing low voltage while the truck is running, that is probably an alternator problem.

The stock lift pump is dying or dead. Stop running the truck before you starve the CP3 and have to spend 1500 bucks to replace that and the fuel pump.

 

What madhat said

 

If I had a dollar every time I heard that...

 

What madhat said X2... Raptor 150 rocks... No return line needed... You might as well get the 150, says Countryboy

 

Thanks Everyone! I'm off for batteries, and in search of 'raptor' I appreciate it!.
