vehicle won't start on 1996 Chevrolet Blazer

I replaced the fuel filter in my vehicle and now when I try to start it the starter just spins Before that happened, it would start if I put some fas in the acrburator but would not stay running. Now it won't even do that. There is no problem with the fuel pump and the starter is new.
