Will the camshaft sensor stop the fuel pump from pumping?

Yes, a malfunctioning camshaft sensor can prevent the fuel pump from operating. The engine control unit (ECU) relies on input from the camshaft sensor to determine the engine's position and timing. If the ECU does not receive the correct signals, it may disable the fuel pump to prevent engine damage or improper operation. Therefore, a faulty camshaft sensor can indirectly lead to a no-start condition due to a lack of fuel delivery.
