84 Ford Bronco will not start

I have 84 full size bronco v8, 5.8 liter, 4b, automatic transmission. I have the timming set and new timming chain, I have changed the alternator, starter, mondulator, fuses,sylinoid switch, plugs and wires, rotary cap and button, and distributor. It is turning over and firing but just won't start. Does anyone have any suggestions besides junking it. This truck has really been beating me.:banghead:

how about the carb.. put some gas down in it

Are you sure the distributor timing is set ?
