97 Cavalier wont start

Heres my story, about a month back I bought a cavalier for $500 and was told that a couple of the fuel injectors and the water pump were bad. When I was driving it home after buying it I was at a stop light when it started to rumble as if it was about to die, which it did. I tried to restart it which came on for about 2secs and then die again and wouldn't start after that, it would just turn over

Well I got the injectors and water pump replaced but it still won't turn on. When I have it in the run position the theft system light stayed on(doesn't blink). And when I check out the new spark plugs I put in and they are not wet so it doesn't seem like its getting fuel. Any idea on what to check first?

I called GM and they told me some info on how to reset the passlock, but none of that worked.
