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.
Coolant Leak From Heater Core
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.
Check Engine Light Due to Gas Cap Issue
A Loose or worn gas cap may cause Check Engine Light to illuminate.
Power Door Locks Stop Working
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.

i have a 2000 gmc sonoma im havin problem with my vechile there is gas goin into my exhaust and i had change my sparks plugs and the wire and even the coil on it is there a reason why its doin tht
I can assure you if you have a feul filter on the car with many
miles the fuel filter can cause blockage and cause the vehicle to stall. To much E-85 fuel or fuel with the added ethenol can
cause dirty and dripping injectors and you should change the fuel filter 25-30 thousand miles/2 years. Rule out the obvious
lest expensive first. You will probaly do some needed PM.
I have a 97 gmc sonoma and it stalls out at times while driving. the mechanic can't find the reason for it happening. He thought it was the module so he changed it but it stalled out again. I suggested that it might be the fuel filter but he said that was not possible. Any suggestions?
one of the reasons why a fuel pump goes bad is lack of changeing the filter and the pump has to work harder to push the fuel through the system
my 2001 sonoma is giving me a hard time
