July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Fuel Pressure Release

WARNING: This page is about a different car, the 1995 Dodge Dakota. 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) White/Dark Blue wire. Momentarily ground jumper wire connected to White/Dark Blue wire for no more than 5 seconds. Injector will energize open, relieving fuel pressure. Remove jumper wires. Fuel pressure is now released.
