1991 Dodge D150 Problems

Fuel Guage May Not Read Correctly

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 should correct this issue.

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.
