How to Remove a 1990 Firebird Formula Ignition
The Firebird was manufactured by the Pontiac division of General Motors from 1967 to 2002. The Formula trim level for the 1990 Firebird was available with an eight-cylinder engine with a displacement of 5.0 liters or 5.7 liters. The procedure for removing the ignition coil is generally the same for all eight-cylinder Firebirds made from 1982 to 1992. The ignition coil for these vehicles is located inside the distributor, which is in the engine compartment.

Disconnect the cable to the negative battery terminal with a socket wrench. This reduces the possibility of electrocution while removing the ignition coil.
2Release the wire retainer on the cover for the distributor cap and remove the cover. Detach the feed wire for the battery from the distributor cap.
3Remove the electrical wiring for the ignition coil from the distributor cap. Disconnect the attaching screws for the cover of the ignition coil with a socket wrench and pull the ignition coil from the distributor cap.
4Place the ignition coil and its electrical wiring into the distributor cap. Ensure that you position the resistor brush properly. Replace the cover for the ignition coil and fasten the attaching screws with a socket wrench.
5Connect the electrical wiring for the ignition coil to the distributor cap. Attach the feed wire from the battery to the distributor cap.

How to Change the Headlights in a 1985 Firebird
The 1985 Pontiac Firebird comes equipped with motorized headlights. The headlight assemblies rise to reveal the hidden headlights when the headlight switch is on. When the switch is off, this mechanism keeps the headlights hidden. All Firebirds are equipped with a manual crank to allow access to the headlights when the vehicle is not in operation. This makes accessing the headlights for replacement easy.
Instructions

Pull the hood latch and lift the hood. Make sure the hood will stay open on its own. If the hydraulic shocks are weak, use a prop rod to keep the hood open during repairs.
2Locate the manual crank beside the headlight assembly. It will be a black cylinder with a rubber knob at the top.
3Turn the knob on the manual crank until the headlight assembly is fully open.
4Remove the perimeter screws from the metal retaining ring that holds the individual headlights securely in the housing.
5Remove the retaining ring and pull the headlight out of the housing. There should be enough slack in the wiring to gain access to the connector at the rear of the headlight.
6Unplug the connector and discard the defective headlight. Plug the connector into the new headlight and place it in the housing.
7Replace the metal retaining ring and install the perimeter screws to secure the headlight to the housing.
8Repeat this process for the remaining headlights. When finished, turn the manual crank in the opposite direction until the headlight assembly has returned to its normal resting position.
