She broke down

Hey fellow gtowners. Today was the first time she gave up on me. Lost throttle response all the sudden and now the car doesn't start anymore. Its not a gasoline problem. Maybe something to do with electricity?

Please help.

Garage
Does it turn over?
Do the other electronics work? (e.g.;lights come on?)
What type of an intake system do you have?
Need more info to do any troubleshooting.

All electronics work, and it does turn over. All original, normal air cleaner etc.

Do you have a points distributor or HEI electronic ignition? Check and see if you are getting spark to the plugs.

If you have a tester see if you have 12 volts on the positive side of the coil with the key on. If you have nothing there start testing voltage from the battery at the starter, and coming from the ignition. Make sure the coil still has the leads tight on their posts.

Make sure the breaker plate ground didn't break. This is the little braided ground strap inside the distributer. It attaches to the breaker plate and the distributer body. As the breaker plate moves back and forth, the braid flexes (hundreds of tousands of times in its' life) and will fail eventually.

When the only tool in your toolbox is a hammer, you tend to see every problem as a nail.

There is no power coming from the coil to the distributor

make sure you have 12 volts coming from the battery. Make sure you have 12 volts at the starter. Make sure you have 12 volts at the coil. If any of those are no search for why, loose wire? bad battery? wire not connecting at the ignition etc. You should be able to find the trail of voltage and see where it stops. Run a wire from the battery to the hot side of the coil to see if it will start.

Pull the distributor cap and have someone crank the engine over while you look at the points. Are they opening and closing? If not, suspect a worn rubbing block on the points. Very possibly worn points or bad condenser. First thing I would check is the points.
