Have you checked the inertia switch? It should be behind the right kick panel. If it is not tripped, smack it with your fist so it does trip, then reset it. The fuel pump will run for only about 3 seconds when you turn the ignition on. Put a funnel into the gas filler neck and have a helper turn on the ignition. The funnel will act as a hearing aid. Also, if you didn't replace the fuel filter, do so. A plugged filter can burn up a pump.
