won't start...it did a month ago

[SigmaPi4x4]

I have a project and I havent been workin on it in the cold so it has been sitting since around late November. I went to get the thing started and the bat was dead so I got a jump. It cranks like crazy but wont fire. I took out a plug and it looked like crap so I replaced them all. I tested and I am getting spark... I only tested 2 but I figured it started before and hasnt been moved so if 2 are still getting fire the rest probably are. I think maybe the gas may be bad... I added heet to the half a tank I have in there. I have read about some computer problems but they weren't getting fire. Any help would be great or ideas for me to look at when its nice this weekend.
oh and i took off the intake hose and spraid some carb cleaner in hopeing it would atleast fire once to get it going...and nothing.

Can you hear the fuel pump on when you first turn the key? I would definately try checkin the fuel pump and if that is good, I would get a fuel pressure tester & check the fuel pressure.

If you have an electrical meter, measure the pump current by removing the pump fuse and measuring the current at the fuse contacts. Should be about 5A. Below 4A you have fuel system problems. Remember the pump turna on for only 3-5 seconds when you turn the key on.
