Installing Fuel Injectors in a 1992 Pontiac Bonneville

The Pontiac Bonneville is a series of cars manufactured by the Pontiac division of General Motors since 1957. The 1992 model is the first of the eighth generation of the Pontiac Bonneville, and represents a major redesign over the previous generation. The standard engine in the 1992 Pontiac Bonneville was a six cylinder, 3.8 L engine with sequential fuel injection. You must remove the fuel rail to access the fuel injectors for this vehicle.

Instructions

1

Disconnect the cable for the negative battery terminal with a socket wrench to avoid the accidental discharge of fuel. Open the filler cap on the fuel tank to relieve the pressure in the fuel tank.

2

Remove the cap for the fuel pressure connection on the fuel rail and wrap a shop towel around the connection. Attach fuel pressure valve J 34730-1A to the fuel pressure connection. Place the open end of the pressure valves bleed hose into a container approved for gasoline open the valve to relieve the pressure in the fuel system. Disconnect the pressure valve and replace the cap for the fuel pressure connection.

3

Disconnect the fuel lines for the fuel rail with a back-up wrench and discard the O-rings. Detach the fuel return line from the pressure regulator. Disconnect the wiring for the ignition coil and electrical connectors for the fuel injector. Remove the mounting bolts for the fuel rail with a socket wrench and disconnect the fuel rail assembly by pulling on both sides of the fuel rail with equal force.

4

Cover the open fuel lines with masking tape to keep debris out of the fuel lines. Release the retaining clips for the fuel injector and discard them. Detach the fuel injector from the fuel rail. Discard all of the O-rings on the fuel injectors.

5

Apply a thin layer of engine oil to the new O-rings. Install the O-rings onto the new fuel injectors and place the new retainer clip onto the fuel injector. Place the fuel injectors into the sockets on the fuel rail so the electrical connections on the fuel injectors face outwards. Lock the retainer clips for the fuel injectors.

6

Install the fuel rail by performing steps 3 and 4 in reverse order. Fasten the cap for the fuel tank and connect the cable on the negative battery terminal with a socket wrench. Turn the ignition on for two seconds to pressurize the fuel system, then turn the ignition off for 10 seconds. Turn the ignition back on and check for fuel leaks.
