Fuel Injector Replacement Directions for a 1991 Camaro

The 1991 Chevrolet Camaro is part of the line's third generation--the first generation to come with modern fuel injection systems as a standard feature. Fuel injectors help regulate the amount of fuel the engine burns, and directly affect the vehicle's performance. Clogged fuel injectors can usually be maintained with fuel injector cleaners and regular inspections. Over time, the parts will become unserviceable and will need to be replaced. The fuel injectors on the 1991 Camaro are easy to access and can be replaced in a home garage.

  Park the Camaro on a flat, level surface and set the parking brake. Open the hood and secure it in place with the hood prop. Disconnect the negative battery cable.

  Open the gas tank to relieve pressure on the fuel lines.

  Remove the sight shield from the fuel injector with a socket wrench. Loosen the screws on the hose clamps and disconnect the fuel lines connected to the injectors. Keep a rag handy to catch any fuel that leaks.

  Disconnect the vacuum hose and ignition coil wire, then unplug the electrical connectors. Remove the fuel injector mounting bolts, undo the retaining clips and remove the fuel injectors.

  Put a thin coat of engine oil on the new fuel injector's O-ring. Place the O-ring in position, install the new fuel injectors and secure the retaining clips. Install the mounting bolts with a torque wrench set at seven pounds.
