I can here the fuel pump run when i turn the key on.

Hi, welconme to AF. Can you check spark or put a scanner on it? Your on a good start to diagnosis. Right now we might assume the trouble isn't fuel , but need to make sure.

It can be many things, but so far my guess is a 12 volt + or - wire/fuse/connection.
