'68 Roadrunner help needed in Montclair, NJ.....ASAP!

Not familiar with your specific car, but start with the basics. Fuel- disconnect fuel line at filter outlet, crank engine ,5 seconds should be plenty. (Careful about starting on fire) . If no fuel appears pull filter off and try again, if still no fuel it is probably the pump. If there is fuel you have a plugged filter.
Check for ignition spark at the plugs. If no spark it could be the points/ condenser, or coil.
Hope that helps. You should get more replies from forum soon with more and better knowledge than I posses.
