1994 GMC Sonoma Problems

Replace Fuel Filter Every 30,000 to Prevent Fuel Pump Failure

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

Electrical Contacts in the Ignition Switch May Fail

The electrical contacts in the ignition switch may fail and result in erratic instrument panel gauge operation or illumination of the Check Engine Light. A failed ignition switch will require replacement.

Heater Core Under Right Side of Dashboard May Leak Engine Coolant

The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.

1994 GMC Sonoma Reviews

My 4wd Sonoma has been an excelent truck. The engine has a bit of a rough idle (from new) but runs strong and gets OK gas mileage. Front brakes wear out on the early side and now I have developed a noise in the front end, maybe worn control arm bushings. The only major repair has been a fuel pump replacement at 70k.
