Cummings Engine Problem

[meledward23]

I have a 96 Dodge One Ton with a 5.9 Turboe Diesel. It has been stalling out in idle for a while and now only starts at random times. The fuel pump and fuel filter have both been replaced.

Any ideas on what might be the problem? Once the truck has the fuel pedal depressed it runs fine. Stop at a traffic light and it may or may not stall. The worst instance is when you put it in reverse. Stalls out 50% of the time.

It could possibly be dirty fuel injectors. Mine (also a '96) acted something like that before I put in larger injectors. When I pulled out the original injectors, they were pretty dirty. Now, you can't turn the key to start without it immediately starting. All it takes is the slightest bump on the starter and it starts and runs fine.

Could it be a problem in the tranny ?

Might be the fuel return or supply line. They can become brittle and leak, allowing the fuel system to loose prime.

It's those darn Cummings engines, a Cummins runs much better. /forums/images/graemlins/grin.gif
Seriously, go Here for some good info.

Exhaust flow clogged?

Forget it. Off to the Evil dealer with this truck again. Of course this is the first time it is for an engine problem and considering the way my wife takes care of her truck it is probably maintenance related.

AND I am ignoring the comment about my spelling. /forums/images/graemlins/cool.gif

my Dad use to have a 97' that did the same thing,and somebody told him that they had a problem with the throttle cable stretching in turn not holding it where it should and idling to low,I thought he said something about a recall on it but I'm not sure,you might want to have it checked just in case,could be a cheap fix for your problem.

Check throttle cable and settings.

There was a recall on the throttle linkage.

You might want to look at what's in front of you. I think it's choking on the exhaust of a Powerstoke. /forums/images/graemlins/shocked.gif

Just kidding....I don't even own one...good luck. /forums/images/graemlins/wink.gif

It may look like that but it's actually pushing . /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

I think you've already heard all the really good advice, but there is one more thing that comes to mind that it could be. The fuel system on the '96 has a prefilter in the fuel thermostat/heater assembly. It sits just in front of your fuel filter on the left side of the engine. I guess it's possible that could be clogged if none of the other fixes noted cause the problem to go away.

I had the leaking fuel feed line problem on my '96 that caused the fuel system to lose its prime. That showed up as needing to crank the engine a long time before it started. Once started, it ran fine.

One other thing is the fuel cutoff solenoid. My rubber dust boot deterioriated and a piece of it jammed the solenoid actuator arm. The truck would sometimes start and sometimes not. I took the boot off and now about every 3 months I have to clean and lube the actuator or it will stick. If my truck won't start, the way I check that is to turn the key to ON and then give the solenoid arm a little tug. If it snaps into place, then I can start the truck and it runs fine. Sometimes if the solenoid doesn't get the valve fully open, it can cause fuel starvation when the truck is running. This doesn't sound like your symptoms, but I guess it's also a remote possibility.
