Throttle Body Injection (TBI)

WARNING: This page is about a different car, the 1994 Plymouth Sundance, 1994 Plymouth Acclaim, 1994 Dodge Spirit, 1994 Dodge Shadow, and 1994 Chrysler LeBaron. However, it is still accessible from the selected car via links, so may be relevant.
  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 no more than 5 seconds. Injector will energize open, relieving fuel pressure. Remove jumper wires. Fuel pressure is now released.
