No because when you have the key switched to the on position even before you start the car the relay switch triggers the pump to turn on and deliver fuel up to the engine to be combusted. If the switch is not working then it cannot trigger to turn the fuel pump on and deliver fuel to the proper location

What will a bad fuel pump relay do to your car?
Bad fuel pump relays aren't very common but i do run across them every now and then. If the relay is bad one of 2 things will happen - if the relay is "open" (unable to complete the circuit)then the fuel pump will not run and the car will fail to start. If the fuel pump is shorted (the contacts in the relay are fused together)then the fuel pump will never shut off...even if you shut the car off and the key is in your hand the fuel pump will continue to run until the battery is drained of voltage. Then the car will not start without charging the battery or "jumping" the car. About the worst thing a bad fuel pump can do to your car is cause it not to start. It could possibly ruin your battery if the battery sits discharged too long. However the odds on that are not great. Just charge the battery - change out the bad fuel pump relay and everything should be OK.
How do you tell if the fuel pump is bad or if it is the fuel pump relay?
If you turn on the ignition key without starting the engine you should hear the fuel pump run for a few seconds. If you do not check the fuel pump fuse and replace the relay before proceeding. If the fuse is good and the relay is good then you know the pump is more than likely defective.
