I have a 2001 Alero. Went out to start it. It ran about a second and died. Wouldn't even hit after that. I let it set for a few minutes, then tried it again. Started instantly. I let it run for about 5 minutes. Shut it off, then it would start for about a second, then die. I can't get it to run any length of time since. Any help?

 

I haven't hit anything. I need to get a manual. I will check the fuel pump. Where is the crank sensor located? Where is the fuel pump reset switch?
