The Fuel Pump Relay and Fuse are key to knowing if the fuel pump is working properly.
Regardless of the vehicle, the electrical circuit is very similar in any of them: The fuel pump relay is controlled by the car's computer or ECM, this relay applies 12V to the fuel pump motor for about 2 seconds at a time of "Contact".
After this, the voltage to the fuel pump is suspended, but when the engine is started, the pulses from the CMP sensor are detected so that the ECM applies voltage to the pump as long as it has pulses from this sensor.
This video explains how the pump works and how it is controlled, it explains step by step how to test it correctly in a few minutes.
