I need some help before I dynamite the old girl.

My 69 GMC cd/1500 has a 350 air etc... The thing doesn't want to crank. I replaced the plugs. Tried to tune the carb. It has an edelbrock carb. It will crank with ether. I put two bottles of alchol in the tank just in case of water. I was planninhg on putting on a new carb, 4bbl intake and headers when I get the funds. I've heard of vapor lock, could this be possible and if so how do you fix it. Since i'm a disbled vet I just sit here day after day with no way to go. I would like to get her running right again. The timing is alaso alittle of. Any help would be appreciated. Happy Saint Pattys day to you all!
