I tried a tire pressure tester and it read 5 psi in off/key on mode, then I tried it while cranking and it didn't move at all.
I then, since I bought the B-12 and fuel filter, put it into the tank and replaced the old fuel filter.
I asked my mom when was the last time she changed it, and she said, never
So after replacing it, and cranking for a few seconds, it fired up fine. I guess the filter was stopped up. I'm letting it idle right now, then I'll take it on the road for some WOTs and filling it up.
