I have a 2000 Dodge Ram 3500 24 valve 5.9 Cummings. I have replaced the fuel pump in the tank, the lift pump, and I put a new tps on it. It ran good for two days and then shut off like it was running out of fuel. I put a brand new tps thinking the other one was bad and it started up with ether but immediately died. Any ideas would be greatly appreciated!

 

Any codes? You said you replaced the in tank fuel pump and the lift pump, just want to clarify do you have an intank lift pump and a lift pump attached to the engine or frame?

 

It thru a tps code. It has a lift pump on the side of the block and it has a regular fuel pump inside the tank.

 

Those are both lift pumps and you only need one. That could be part of the problem. From the factory your truck came with the lift pump (lp) on the block but they weren't adequate to feed the vp44. Dodge then came out with an "upgraded" lift pump that went in the tank that dealers would put on when the original failed. These are also crap. What I would suggest if you can swing it is remove both of them and put a fass, airdog, or raptor pump on. Since you have the intank lp you will also need a draw straw. In the mean time, take the fuel hose that is running to the block mounted lp off, put it in a bucket and bump the starter to see if the intank lp is working. If it is remove the block mounted lp.

 

Did you calibrate the new tps?

 

Okay thanks I will give that a try but I am getting fuel to my fuel lines. What would be making it not stay running.

 

Yes I calibrated it.

 

Do you have a fuel pressure guage? If so what is it reading? Here is a link to blue chip diesel https://www.bluechipdiesel.com/vp44_diagnostics.html
Lots of info and tests you can do. Also check out the troubleshooting pages.

 

okay thanks! I will check it out!

 

When you bleed the injectors do you bleed at least 3 of them?
