There is a procedure to check base timing. I have done that when I replace the complete ignition system. Timing is on, my question is, I was told long time back the the car in the 80's era had a fail safe mode. If the computer went bad, it would lock itself in a run mode, no advance, no retard. As I understand it, it was to get you home or to the dealer. If this is true, how do you check the computer to see if it is working properly. It does control timing, fuel mixer, and vaccume related sensors. Don't want to buy a new one to find out that's not problem. I still need to check fuel tank as you suggested. Thanks again.
