1991 Dodge D350 Problems

Air Conditioning Not Cold

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.

Fuel leak from injector

Engines using a throttle body fuel injection system may develop a fuel leak from the fuel injector nozzle or the injector o-ring seal can cause any of the following: Hard starting, rough idle, black exhaust smoke, and poor fuel mileage.

Diesel engine hard starting issues

Diesel engines may develop a hard start or no start condition due to any one of  the following issues: Low fuel pressure, air entering the fuel system, and loss of fuel system prime. Our technicians tell us that the rubber inlet hose at the back of the injection pump and the lift pump are common causes for these concerns. Lack of fuel to the injection pump can damage the pump due to lack of lubrication, when this occurs it is not uncommon to replace the lift pump, injection pump, and fuel injectors.
