2003 Chevrolet Trailblazer Fuel Pump
The 2003 Chevrolet Trailblazer uses an internal combustion engine that burns gasoline to run and drive. The fuel pump sends fuel from the fuel tank to the engine by pumping constantly. If the pump fails or begins to fail, the Trailblazer will struggle to run. When that happens, usually around 100,000 miles, it's time to replace the pump. Find a replacement Chevrolet Trailblazer 2003 fuel pump at AutoZone to get back on the road quickly.
Signs of a Bad Fuel Pump
When the fuel pump begins going bad, you're likely to notice a whining noise from your fuel tank, a loss in power and fuel economy, surges and power losses, and you might notice your engine sputtering as you drive. Eventually, the engine won't run at all, and this is when the pump is dead. If you have these problems, you need a replacement Chevy Trailblazer fuel pump. Find a matching pump at AutoZone based on your Trailblazer's year, make, model, and engine size.
Replacing a 2003 Chevrolet Trailblazer Fuel Pump
Jack up your Trailblazer and support it safely so you can climb underneath to start the repair. Disconnect the fuel lines leading to the fuel tank and unhook the tank straps to free the tank. Lower the tank to the ground to access the fuel pump access hatch. Remove any wires and unhook the hatch to open it up. Unscrew a ring if present, and remove the old fuel pump. Drop in the replacement before adding back the fuel lines and the wires. Attach the access hatch, lift and secure the fuel tank, replace the tank lines, and you're done.
