Instructions on How to Replace a Fuel Injector for a 4 3 Litter 1997 Blazer

The Chevrolet Blazer was a mid-size sport utility vehicle made by General Motors from 1983 to 2005. The second generation of this model was in production from 1995 to 2005 and all of these vehicles were equipped with a six-cylinder 4.3-liter engine. Each cylinder of an engine has its own fuel injector, which delivers fuel and air in a precise sequence. You can replace an individual fuel injector on the 1997 Chevrolet Blazer.

Instructions

1

Remove the air cleaner with a socket wrench and disconnect the cable on the negative battery terminal. Open the filler cap for the fuel tank to relieve the pressure in the fuel tank.

2

Press the two tabs on the fuel injectors electrical connector together, and pull the electrical connector up to disconnect it from the fuel injector. Remove the cover for the fuel meter with a socket wrench and discard its gasket. Lift the fuel injector from the fuel meter carefully with a small pry bar.

3

Remove the small O-ring from the nozzle of the fuel injector. Detach the fuel filter from the fuel injector by carefully rotating the fuel filter back and forth. Remove the large O-ring and washer from the injector cavity of the fuel meter.

4

Apply a thin layer of transmission fluid to the small O-ring and push it onto the nozzle of the injector until it is flush against the fuel filter for the injector. Install the washer into the cavity of the fuel meter and apply transmission fluid to the large O-ring. Seat the large O-ring against the washer so that it is flush with the top of the fuel meter.

5

Align the raised lug on the base of the fuel injector with the notch in the cavity of the fuel meter. Press the fuel injector down firmly to ensure that it is fully seated. Install the cover for the fuel meter and its new gasket. Attach the electrical connector to the fuel injector. Start the engine and check for fuel leaks.
