2005 dodge 2500 diesel help!!!!!!!!!!!!!!!!

restricted breather hose and air filter.

USUALLY A SIGN OF OVER DELIVERY OF INJECTOR PUMP IS THERE EXCESIVE SMOKE FROM EXHAUST ?

It's most likely the return line to the fuel tank. It probably has a bad fitting.

just a o ring 25 cents

Heres a belt diagram for a 2005 dodge ram 2500 series, with the5.9 diesel engine hope this helps.

Could be a clogged fuel filter. Maybe your injector pump is going bad?

I'm no expert but I had a similar problem. On October 10th, 2009 I smelled the same thing. I own a 2005 Dodge Ram 2500 Cummins. It has about 150,000 miles. The next day I checked under the hood and found that the #4 injector tube was leaking and providing a fine mist of diesel fuel all over the engine compartment and firewall. The trouble seemed to be from the plastic clamp that is suppose to hold the tube in place. It was very loose and I feel that is the reason for the break/leak. The leak was right at the compression fitting on the tube where it passes through the nut that connects it to the injector. I called around to find the replacement parts and the dealer wanted about $75 for the tube and about $12 for the plastic clamp. I found the Cummins dealer wanted around $21 for the whole assembly and that included the plastic clamp assembly as well. Don't go to the dealer!!! I replaced the injector tube in about 20 minutes because it took about 10 to find my tool box. The repair was easy and everything is back to 100% fine and no leaks. I believe that if I had to replace injector tube # 5 or 6 it would have been a lot bigger deal because they are so far back and under the firewall. Difficult for someone without any more than standard wrenches. The only trouble I had was getting something of the proper height to stand on for good leverage. This one is a do it yourself and save project.

first place to look would be your lift pump (fuel pump located behind the fuel filter housing). listen to it when you turn the ignition on, it should run for a few seconds and if you bump the starter it should run for about 30 secs. if you dont hear it running that is most likely your problem
