Grrr truck wont fire!

[Mikec10]

So my truck has been sitting for about 6-8 months without being started, tranny went out right before the start of cold weather so i put it on the side of my house and waited till now. Well it wont start, i'll charge the battery enough to get it to spin over a few times. I know its getting fuel, i know its getting spark and i know it has compression, but it wont fire, it does sometimes but just dies almost instantly, Now i cant think of anything i thought maybe the coil wasn't getting a constant voltage so i made a relay/ignition switch and it sputtered and died. It has about 1/2 a tank of gas, now is it possible the gas is bad? Friday i think im going to just stick the fuel line into a bottle with new gas and try to start it with that.
