You can't burn out a pump by revving the car. The pump gets the same voltage whether you're idling or are full throttle at max rpm.

There is a simple test for that.

The pump is supposed to deliver at least 1 liter of fuel in 40 seconds at the return fitting from the Fuel distributor (Fuel pressure regulator is built into the distributor on your car).

You do that by having the engine off and jumping the fuel pump relay.

More details on this procedure:

When doing this test make sure you take all safety precautions when working with gasoline (fire extinguisher and safety gear) and be away from any expensive things (such as houses)

If it passes this test it will mean that:

-Fuel filter is good
-Fuel pump is good
-No blockage at the tank
-Fuel accumulator is good (At least shouldn't affect running if there's a small leak inside)
-Small filter at the Fuel Distributor is good
