Q: Car won't start the next day after getting gas, but was able to drive to work and back home.

CYesterday idk if my car was out of gas or what. I don't want to say battery because the radio and lights would come on and it would rev up. Then I got my jerry can and walked to the gas station and put about 5 gallons in my car. So then I let it sit for a couple minutes and tried to start it up and it would rev up but not start up. So then i guessed maybe the battery, so then I used one of those Jumpstarter things for the battery and after letting it charge for a minute, it started up. I drove to work fine, then I filled it up with gas, then went into work. So the car was off for 8 hours, when I left I started it up just fine, drove home and went to sleep. Now about 12-14 hours later it is doing the reving up but that's it, not starting up and I know it's not the gas. I don't know if maybe it's the alternator (I hope not) or the battery or what. All my lights come on, the radio is on, i don't know what's wrong. It's an Acura legend 1995 and I mean it's kinda cold outside, and I park o

My car has 219074 miles.
