Electrical problem
1979 Pontiac Firebird V8 Four Wheel Drive Manual
----------------------------------------------------------------
My ignition module went out and I replaced it and it ran fine for two days then went out again. What could be the problem?

Cross these two terminals as shown, then turn the key on. Count the flashes, a 22 will flash as 2 flashes then a short pause, then 2 flashes, if more than one code is stored, the pause will be longer. The codes will display three times and end with 12. Write them down and post here. This connector is right under the middle of the dash...

This is a 1979 trans am. It does not have a GM 1995 & older diagnostic connector.
