Fuel Pressure Release

WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, and 1995 Dodge Caravan. 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. Slowly open fuel tank cap to release pressure in tank. Disconnect 2-pin injector connector at edge of throttle body. Connect a jumper wire between injector connector (injector side) Dark Green/Orange wire and battery positive terminal.
  2. Connect another jumper wire to injector connector (injector side) Light Blue wire. Momentarily ground jumper wire connected to Light Blue wire for no more than 5 seconds. Injector will energize open, relieving fuel pressure. Remove jumper wires. Fuel pressure is now released.
