1991 Dodge D250 Problems
Carbon buildup on the top of the piston is common. Over time this can lead to symptoms varying from light ticking to knocking noises. Performing a fuel injector cleaning procedure can often help the condition by removing some of the piston top deposits.
A condition may develop where the fuel gauge reads empty with too much fuel still in the fuel tank. Our technicians tell us that installing a new wire harness that provides a common ground for the fuel gauge and sending will correct this issue.
The powertrain control module (PCM) may fail resulting in a lack of AC cooling. The lack of cooling could be caused by evaporator freeze-up due to the AC compressor staying on continuously or conversely, not coming on at all. Proper diagnoses of the PCM should be performed before replacing it for this concern.

I bought this truck used with many miles on it. The engine had been rebuilt. So far its been a very good reliable truck. Hauled many things and even a medium sized pop up trailer with no problems. Interior is not in the best shape and appears to have been built shoddy to begin with. Exterior all the paint was peeling bad and looks like that might also been a factory issue.
