Fuel Pressure Release

WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, 1995 Dodge Caravan, and 1995 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: ALWAYS relieve pressure before disconnecting any fuel injection-related components. DO NOT allow fuel to contact engine or electrical components.
  1. Turn ignition off. Disconnect negative battery cable. Slowly open fuel tank cap to release pressure in tank. Remove fuel rail pressure test port cap. Obtain fuel pressure gauge/hose assembly from Fuel Pressure Gauge Set (5069).
  2. Place open end of fuel pressure gauge/hose assembly in an approved gasoline container. Connect other end of pressure gauge/hose assembly to test port. As fuel pressure gauge/hose is tightened onto fuel rail pressure test port, fuel pressure will bleed-off into container.
WARNING: Always relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
