It sounds like a nasty vacuum leak in the evap system. Check all of the hoses , even at the canister in the back of the car underneath. There are vac lines there,, one could be off, one or more could be cracked or broken. Have you changed the fuel filter. It could be clogged. You say you don't hear the fuel pump run when you turn the key to on and it appears you have a vacuum leak in the evap system... the vac hoses AND fuel pump wiring are all in the same general physical location... Take a look.
