2002 GMC Sonoma Problems

ABS Light Due to Brake System Control Unit Failure

The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.

The Fuel Pump May Fail Causing the Engine to Stall or Crank Over But Not Start

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.

Driveability Problems Due to Internal Distributor Fault

The distributor may develop internal faults. This can cause a rough running engine or stalling condition and the Check Engine Light may or may not illuminate. The distributor should be overhauled or replaced to correct this concern.

Do routine maintenance and it will run forever, I hope. Would rather spend a couple ...
I have a 02 GMC Sonoma and the passager side cab is rusting. The thired door handle broken because its plastic. Its automatic and some times when shifting it does not seem like it wants to shift. The daytime running lights work but when I turn on the turn signial they go out until the turn signial goes out.
A door pin was replaced and then the third door was readjusted and wind noise is gone. Have problems with seat belt on occasion not retracking properly.
