2500TurboDodge

My dad has a 1997 dually 4wd, cummins diesel, automatic and we tow 5 horse up and back to ny and the truck goes up hills doing like 60 65 and i know the truck should be better then that the truck has no power and will not tow. When we start it up it puts out a lot of white somke we sent the injectors out to day and hope that it fixs the proble. We tow hay back from ny to ct sometime on a 9 ton trailer but most of the time we tow the horse trailer back with 90 bales of hay in it so whats going on with the truck is it the injectors or the lift pump. And the truck stalls a lot when we get of the highway and try moveing it around at the shop it stalls when we stop hard

Thanks

When was the last time the timing was checked on it? Might need to adjust that. How bout fuel filter? If it hasn't been changed in a while, then it needs to be. White smoke is not good smoke.

I do not know about the timing but the fuel fulter had been change and the injector place just called and sat that there were fine and thats not the problem

Couldn't have said it any better probably a combination of worn parts.

Does the 97 have a lift pump on them if so were

ddestruel

Look down below your fuel filter or for that matter look up from underneath on the driverside of the block between the motor mount and the starter there is a pump assembly sticking out of the side of your block

I would definatley check timing. My truck was the same way and the timing was off. Good Luck

The lift pump should not be the problem on a 97. I would check all of the previously listed items plus the overflow valve on the injection pump, stock muff. and cat (chunck em), and the air filter.
Good luck

I would check all of the above ESPECIALY timing. That thing probly needs to have a good run through, things like clean the fuel screen, replace return lines, timing, tighten intercooler clamps and such, adjust valves, etc, etc.... How many miles are on it?

2500TurboDodge

About 95,000

Stalling problem might be simply the idle adjustment. Should idle about 850 rpm in neutral with a warm engine. It can fall off on these trucks as the idle stop wears, and results in stalling during parking lot maneuvers, etc.
I agree you have other problems regarding power and smoke.

Also make sure that the fuel shut off solenoid plunger is sucking completely up into the solenoid. Otherwise, there will be a shortage of fuel.

Got Smoke?

I disagree. Check the fuel pressure with a banjo bolt at the fuel inlet to the injection pump. I had to replace my lift pump on my truck.

my lift pump was bad too but the truck ran fine at lower rpms IE 2900 and under but got really bad MPG. like 10 or so. new pump and I get a LOT better MPG
