How to Repair & Install Fuel Injectors on Pontiac Sunfire

81

The Pontiac Sunfire is a compact car, manufactured by Pontiac from 1995 to 2005. This vehicle uses Pontiac’s J platform, and has a four-cylinder 2.2-liter engine with sequential fuel injection. Each cylinder has its own fuel injector, which delivers pressurized fuel to the cylinder in a precise sequence. The fuel injectors are generally not serviceable, so the repair procedure consists of replacing the faulty injectors.

Tools Used: Tools, Socket wrench set, Shop towel, Torque wrench

Repairing & Installing Fuel Injectors

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