There is a fuel pump inertia switch in trunk. this is designed to trip and cut pump off in wreck. if it gets bumped can trigger and cut pump off it is a button you push should be a sign on side of trunk showing it
I had a situation on my '91 Town Car where the Fuel Pump Fuse was repeatedly blowing after a few seconds of running the car.
I replaced the Fuel Pump RELAY (and the Fuse one more time) which resolved my issue. Apparently the relay was failing, allowing too much amperage across the circuit, and blowing the fuse each time. With both replaced, the engine starts and runs fine now.

Is the fuel pump inertia switch a closed circuit when it is working correctly/on?
