Some cars have a safety switch that turns off the fuel pump in a wreck on the rear of the car.....don't know if the 85 has that.

No GM cars or trucks use a "Ford" style inertia switch. All of them run the fuel pump via fuel pump relay for the first 5 or so seconds of operation, starting as soon as the ignition key is turned to the crank position. As soon as the oil pressure sender sees about 4psi, the oil pressure sender supplies power to the fuel pump.

Check all fuses, especially CCC fuse, ECM1 and ECM2 fuses and there should be a fuse marked  Fuel Pump 2  if it is labeled that way, you need an owners manual for quicker identification. If the fuse is ok, remove the fuel tank cap door and remove the plastic boot. This gives easy access to fuel pump hoses and wiring. There is a 3 or 4 wire connector. Black is ground for the fuel pump. grey is power to the fuel pump. Purple is sending unit. Senders go bad on these things more than fuel pumps so dont be surprised if it is actually out of fuel. Unplug the connector, use a test light or volt meter to check for ground on the black wire(Harness side of connector) and power to the grey wire while cranking the engine.

So is the only place for the circuit breakers next to the passenger door? We have no idea where any other circuit breakers are and the fuses look good.

You have to check at  the fuel pump output hose to see if you gas leaving the pump going to the fuel filter,look like you have a crushed or kinked fuel line..If no fuel is leaving the pump, it is not running ,you can hear the pump running for 3 seconds,key in the on position.

Have you checked to make sure your fuel filter isn't plugged?  Accident to rear could've dislodged sediment in the fuel tank and gummed up the filter.

There are no circuit breakers for your fuel pump. Your owners manual will tell you where the fuse boxes are.

Not that I am a expert but I will throw this out for thought. I was having issues with my c4 running properly and thought it was fuel pump. It wasn't it turned out to be a clogged catalytic converter, it had not been run for 6 years and the internals were rusty .I mentioned this because you said that exhaust system was damaged so just to be sure make a quick check. The other thing it could be is the sock on the fuel pump could be clogged also as well as the fuel filter.
