Relieving Fuel System Pressure


  1. Remove the fuel pump fuse from the fuse block, or remove the fuel pump relay or disconnect the wiring harness at the fuel tank while the engine is running.
  3. The engine should run and then stall when the fuel in the fuel lines is exhausted. When the engine stops, crank the starter for about 3 seconds to be sure that all the fuel pressure in the lines was released.
  5. Install the fuel pump fuse, relay and or wiring harness connector after the repairs have been made.

The fuel pressure should be relieved whenever the fuel system is to be opened up for repairs.
