Can you hear the pump running when you first turn the key on? If not check the fuse and relay under the hood. If these are good check the wiring for the pump as it runs down the frame rail to the tank. If you do hear it running you may want to replace the filter.

How can you be sure fuel pump is faulty?
If you have power to the fuel pump and it will not run it is defective. If it runs but a fuel pressure test verifies that the fuel pressure is low and you replaced the fuel filter then the pump is defective.

Check the fuel pump pressure, the fuel pressure regulator may be bad. Need to know year, make, model and engine size to give you fuel pump specs.
When the fuel pump relay goes bad does that slow the flow of fuel to the engine?
If the fuel pump relay goes bad your fuel pump will not get power and you will get no fuel. If your fuel pressure is showing too low your pump is either weak and needs to be replaced, your fuel lines are restricted somewhere ( or possibly leaking ) or your fuel filter needs to be replaced.

Replaced fuel pump on 1994 safari started and ran but when shut off would not start again?
When you replaced the fuel pump did you replace the short fuel line from the pump to sending unit? I didn't when I replaced the fuel pump on my 94 Safari and I had that problem. Also check to see if the pump is running when you turn the key on it should run for a few seconds. If pump works replace fuel filter. If still no luck check the fuel pressure. It should be around 80 to 100 psi.
