Help! What could be wrong with my 2001 Dodge Truck?
I have a 2001 Dodge Dually truck. It is a 3500 4 X 4. 5.9 Turbo Diesel Engine.
Here is the problem. When you are driving at around 30 to 35 miles per hour it starts missing. It just hesitates for a little. When you accelerate up to about 50 it will stop most of the time. We also pull a 12,000 pound trailer with the truck and it will also do this while we are pulling it and have the overdrive shut off.
However, when my husband unhooks all the battery cables from everything and waits a couple of minutes and then hooks them back up, it stops doing it for a while. Then after about 100 to 200 miles later it will start to do it again. What could be causing this? We had a new injector pump and fuel pump put on it less than two years ago.
Help!
Don't know what happened to my edited info but anyway. The injector pump we had replaced was a factory one. At that time the guy said it was the injector pump that was bad, but he went ahead and put a new fuel pump in too because he said it was hard to get to if it ever needed replacement. Now I'm wondering if it wasn't just the fuel pump that was bad and we got one put over on us. It cost us $1,400 to have them replaced.
Oh, the injector pump and fuel pump were replaced less than two years ago. I forgot Yahoo deleted that part of the information. So, I wouldn't think it would be bad again so soon since it didn't go bad the first time for eight years.

your gonna need another injector pump, that 1 or 200 mile period that it is running fine is just the time the computer is re learning everything and is in closed loop. when you had your injector pump replaced did you stick with the factory lift pump or did you go with an aftermarket one cause the factory lift pumps are just about worthless they dont supply enought fuel to keep the injector pump cool get an aftermarket lift pump i personally have an air dog in my 02 and i have had no problems with injector pumps since, also do you have a fuel pressure gauge? if you dont i STRONGLY recommend one and i would never let the pressure get below 5 psi ever, anything below that and you injector pump is not getting sufficent flow through it to keep it cool and thats why they go bad 99% of the time
