GMC Sierra 1500 HD Problems

"No start" Caused By Failed Fuel Pump

The fuel pump may fail causing the engine to stall and not restart.

Fuel Level Sensor Failure

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

Stalling or Low Engine Idle Speed Due to Dirty Throttle Body

GMC Sierra 1500 HD Reviews

Pretty nice truck to drive. Great for mountain trips and towing. Cons: had a few things break down, fuel pump x2, water pump, alternator, transfer case replacement. Overall I like the truck, but it's not real practical due to gas mileage.
