Crank no fire fuel pump is pumping

02 Chevy Silverado 1500 5.3L had the battery light
come on and flashed at me for 2 days then stayed
on followed by the check engine light. When i was
driving truck started trying to cut out and I got it
home shut it off and now it wont fire. It just cranks
over sounds like it tries to catch but it doesn't and
won't start can hear fuel pump working with key
forward. Im stumped need ideas.
