Car won't start

Since no-one has responded,I'll get the party started I guess.
A '77 GTB is pretty straight forward. We're looking for spark, fuel and that they're being provided in the right amounts at the right time.
I'd pop the aircleaner, look to see if the accelerator jets are pumping in fuel when the throttle linkage is activated. Don't overdo it. We just want to know all throats are getting gas. If not we'd work back through the fuel system looking for a blockage or failure.
If that quick gas test seems OK, I'd move on to the spark. Both low and high tension circuits are diagrammed in your manual of course and look pretty normal except for the throttle linkage activated micro-switch controlling which points are activated.
Odds are its a loose or poor contact in your low tension circuit somewhere. The HT stuff tends to give some warning in my experience with other marques.

There is some overlap between your radio system and the ignition as the ignition has supressers on both coils, plug leads etc. Nothing that results in non-starting though, I would think.

Good luck and maybe my gentle bump might get one of the more expert members to add their help here.

 

Did you perhaps flood the engine?

Ps. Fit a electric antenna.

 

I'd check the electrical next. Are the spark plugs sparking? I would bet not.

If they are then move to the distributor. Not sure how yours works with the flywheel sensors and all but if you have spark and gas, all that's left is timing.

Don't have the '77 US manual but over here in Oz the previous year, '76, was all about dwell angle and timing lights. No flywheel pickups,

 

You stated that the "car wouldn't start. So when you turned on the ign switch did you hear the fuel pump running. Next does the starter turn the engine over. I would put the dwell meter on and have someone crank the engine and see if you have dwell on both dizzy's. I would also take a spare sparkplug and attach it on one of the wires and hold it to ground and see if you have spark. Also when you look into the carbs make sure no one is cranking the engine, you don't want it to backfire and burn you. OK check to see you have 12v at the coils with the ign switch switched on. So once again with the 77's all you need is gas and spark.
