How to Troubleshoot a Chevrolet Camaro Fuel System
A drop in engine performance could signal a problem with the fuel system on a Chevrolet Camaro. A sputtering engine, an automobile that is difficult to crank and engines that stall are all symptoms of some trouble with the fuel system. Troubleshooting the fuel system in a Chevrolet Camaro can be accomplished by following these steps.
Items Needed:
- Fuel pressure gauge
- Quick-connect separator
- Towel
- Park the Chevrolet Camaro on a flat surface and apply the emergency brake.
- Scotch the tires by placing a brick or large rock in front of and behind one of the tires.
- Disconnecting the battery’s negative cable first.
- Release the pressure from the fuel system by removing the fuel fill cap.
- Shield arms and face by placing a towel over the fuel pressure valve fitting and then release the valve.
- Disconnect the fuel pump pressure regulator from the vacuum line.
- Examine the vacuum line for presence of fuel. If there is fuel in the line, the culprit is probably the fuel pump pressure regulator, which will require replacing.
- Reconnect the vacuum line to the fuel pump pressure regulator, if there is no fuel in the line.
- Remove the test port cap from the fuel pressure valve to test the fuel delivery.
- Connect the fuel pressure test gauge into the valve to check for pressure. The needle should measure 40 pounds of pressure per square inch.
- Remove the fuel pressure test gauge and replace the cap.
- Locate the fuel filter near the pipe in front of the rear axle.
- Utilize a quick-connect separator tool kit to remove the filter for inspection to determine if it is clogged.
- Reinstall a new filter, if the old one is clogged or if the car has been driven 15,000 miles since the last time it was replaced. The outlet fitting should be torqued to measure 22 pounds.
- Replace the fuel pump and re-pressurize the fuel system.
- Attach the negative battery cable.
- Switch the ignition switch to the on position then back off for several times.
- Examine the surface under the car for fuel leaks. If no fuel leaks are present, it should be safe to start the automobile.
