Can a fuel pump cause your car to not start?

Yes, a faulty fuel pump can absolutely prevent your car from starting. The fuel pump is responsible for delivering fuel from the tank to the engine. If it's not working, no fuel reaches the engine, and the car won't start. This can be due to a number of reasons, including:

* Pump failure: The pump itself might have worn out or broken down.

* Electrical issues: A blown fuse, faulty relay, or wiring problems can prevent the pump from receiving power.

* Low fuel: While not strictly a fuel pump problem, a very low fuel level can sometimes prevent the pump from drawing fuel effectively.

* Fuel pump filter blockage: A clogged fuel filter restricts fuel flow, effectively starving the engine.

If your car won't start, a malfunctioning fuel pump is a strong possibility, and it's important to have it checked by a mechanic.
