2003 S10 won't start - video attached



I have a 2003 S-10 that won’t start. It started fine before it sat for about 5 months and when I tried to start it recently it had a dead battery, so I put a new battery in and now it will crank but not start. You can listen to it trying to start on this video I took and uploaded to youtube: https://www.youtube.com/watch?v=1-nobwIC4XA
Gas tank is full, but stepping on the gas doesn’t seem to have any affect when trying to start. Any advise or thoughts would be helpful. Thanks!
