I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.

are you using the original key ?? sounds wear but in the key switch there is a sensor that detects if the right key is in use otherwise it will kill the power to the fuel pump or it can be a fuse look under the left rear passanger seat there is another set of fuses and the other set of fuses are on the driver side near the door and there is another set of fuses and relays inside the hook next to the battery

1st ensure the fuses are all good and there is fuel in the vehicle and your not getting a false reading by tapping on the tank ..does it sound Hollow oe Empty / another way is turn on the key and listen for the pump to work a slight humming should be heard ...if so locate the fuel bar and cap screw depress the valve shielding your eyes with say a towell and see if gas dispurses make sure the key is on while doing this if no gas is there or fuel pump is heard then it may be either a bad ground to the unit or the fuel pump itself corroded connections will contribute to this as well unclipping and reclipping the connection togeather should allow a better connection
