Truck won't start?

What is your question?

2002 envoy the battery died because I left the key on jumped it I get all my lights but no starter crank I can crank the starter by jumping it but still won't fire up i have power at the fuse box and when i have someone turn the ignition to crank i get power to the crank fuse in the box so I'm guessing that means that the ignition is working. I have no security light but i have tried the relearn process for the key pass over and over with still no luck.
