Just bought 1979 firebird at auction. Cannot lock ignition with key. Is my problem most likely: a) incorrect ignition key b) faulty ignition lock c) steering column locking mechanism FYI - door locks operate with trunk key, not ignition key. Also, can remove ignition key with engine running.

Should it still start after bypassing the lock and using the igntion control module with a screwdriver?
Your best bet take it to a qualified repair shop !

- Faulty spark plug (s) - Faulty ignition coil (s) - Clogged or faulty fuel injector (s) - Intake air leak - Fuel injectors harness is open or shorted - Fuel Injectors circuit poor electrical connection - Ignition coils harness is open or shorted - Ignition coils circuit poor electrical connection - Insufficient cylinders compression - Incorrect fuel pressure What does this mean?

You either have a bad starter or ignigtion switch. When you turn the key on does everything else come on? I would check the starter first if you have power to everything.

u have to move the switch,,there should be tree screws Philip head,,

they are connected to the ignition switch on the outside of it.

It should be purple

Caution:On models with a Delco Loc 2 or Theftlock audio system be sure the lockout feature is turned off before proceeding

• Disable the airbag system
• Remove the tilt lever if equipped
• Remove the upper and lower steering column covers

Ignition Switch

• Remove the ignition switch retaining screws
• Detach the ignition switch from the steering column housing assembly and unplug the electrical connectors

Key Lock Cylinder

• Turn the key to the run postion
• Depress the lock button and remove the key lock cylinder

Then you needf to change the ignition lock asap. Rick
