Here's why:
* Fuel Delivery: The fuel pump is responsible for drawing fuel from the tank and delivering it to the engine injectors.
* Pressure: The fuel pump creates the necessary pressure to force fuel into the injectors.
* Injection: The injectors spray fuel into the combustion chambers, where it mixes with air and ignites.
Without the fuel pump, there would be no way for the fuel to reach the injectors, and the engine wouldn't have the necessary fuel to operate.
Possible Scenarios:
* Mechanical Failure: If the fuel pump fails, the engine will not start or run.
* Electrical Issue: A faulty fuel pump relay or wiring could prevent the pump from receiving power and operating.
Important Note: If you are experiencing fuel pump issues, it is crucial to diagnose and address the problem promptly. Running an engine without proper fuel delivery can lead to engine damage.
