No, not unless the relay is stuck closed. It will then run but the pump will overheat and self destruct.

Car not getting fuel?
Bad fuel pump, blown fuel pump fuse, bad fuel pump relay, or clogged filter.
The gas will not go to the engine to start the car up?
Bad fuel Pump? Bad fuel pump relay? Plugged fuel filter?
Will a bad fuel sending unit cause your car not to run?
If you're talking about a fuel pump, then yes, a failed fuel pump or fuel pump relay will keep a fuel-injected car from running.
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.
Would a bad fuel pump relay stop the car from running?
Yes it could.
Can a fuel pump relay cause a car to stall after starting?
A fuel pump relay switch can cause your car to stall after starting. A malfunctioning fuel pump relay switch can cause your car to not start at all.
What fuse do you change if your car doesn't start?
If it cranks but doesnt start it could be your fuel pump relay or your fuel pump could be bad.
How can you tell if a fuel pump is bad or if it is the fuel pump relay switch?
You can swap relays within the relay center with another relay that matches, but in most cases it is seldom the relay at fault, it is probably a bad fuel pump.
What causes a car to lack fuel?
If it lacks fuel then someone didn't put any in the tank. If it lacks fuel pressure then it could be a bad pump, fuel filter stopped up or a bad fuel pump relay.
Would the relays along the fire wall make your car stall?
The relays along the firewall will make your car engine not to start. The fuel pump relay is what turns on the fuel pump when you start your car and powers it down when you shut off the ignition. The engine control module (ECM) uses the fuel pump relay to control when the fuel pump is on. The fuel pump relay supplies electricity to power up and power down the fuel pump. Once the points burn or the coil breaks, the incoming voltage to the fuel pump is blocked and your car engine cannot start. If engine takes a long time to crank up, it probably is due to a bad fuel pump relay. Another way you can tell the fuel pump relay is bad is when you don't hear the fuel pump run for a couple of second when you turn the key in the ignition forward to start the car.
Why does your car seems its starving for fuel and wont start?
Fuel filter clogged, fuel pump not running caused by either blown fuse, faulty fuel pump relay, or bad or weak fuel pump.
Will your car shut off if the fuel relay is bad?
The vehicle may shut off during use if the fuel pump relay goes bad. But it could go bad and the relay shuts off, or the relay gets stuck open (which does not happen often). if the relay gets stuck open then most likely the fuel pump will not shut off (unless the relay is removed) which is dangerous. Also it all completely depends on the wiring of the car. Also, if the fuel pump relay goes bad and shuts off, the vehicle may not start back up until it is replaced.
