Has the fuel filter been changed? Have you checked the current draw on the fuel pump? Are you absolutely sure all of these pumps are bad? A burnt or poor connection at any point can cause a pump to refuse to operate and it may even be erratic in nature. Pardon the questions; just looking for a bit more to go on. Offhand, a short (if it exists) should not take a pump out. ---

Maybe the short is in the wiring TO the pump…Or in the relay with the burn marks… ---
