1994 GMC Sonoma Problems
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.
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.
Our technicians highly recommend that the transmission is serviced every 30,000 miles to avoid problems and maintain optimal operating order.
The power door locks may stop working in one or more doors due to a failed actuator. Replacement of the failed actuator should correct this concern.

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.
