2000 4.6 L won't start
 

I have a 2000 F150 with 4.6 L. It was low on gas (low fuel light on) and drove for a while with it on. Parked it and when I tried to start it again it won't fire. I put a couple of gallons of gas in, changed the fuel filter and it still won't fire at all. I don't have an owners manual so I don't know where the fuse is for the fuel pump. I did notice a 15 amp fuse in the box under the hood is blown but when I put another in it made now difference. Any suggestions anyone?? How about a diagram for my fuses for future reference?

Thanks,

Kyle
