  Q: How to Check Fuel Pump and Fuel Pressure and Troubleshoot Low or High Fuel Pressure?

  A: To find the fuel pump, look in the fuel tank. It will be heard when the ignition is turned on. To check fuel pressure, use a fuel pressure gauge with a hose and adapter. After relieving the pressure, remove the rear seat cushion and access cover, then connect the gauge. Start the engine and compare the gauge with the specifications.
