Frequently Asked Questions (FAQs)

1. What does a fuel pressure switch do?

A fuel pressure switch is part of the fuel pump assembly and is responsible for detecting evaporative leaks in the fuel system. It reads the pressure in the fuel system and helps identify issues like loose or faulty gas caps.

2. What sensor turns the fuel pump on?

The fuel pump relay is activated by the ECM (engine control module) after receiving a signal from the crankshaft position sensor (CKP). Once the engine starts and reaches idle speed, the ECM keeps the fuel pump relay activated using the CKP signal.

3. How is the pressure controlled in the fuel injection system?

The fuel pump maintains the pressure in the fuel rail by continuously delivering fuel to the common rail. A pressure sensor monitors this pressure, and the controller adjusts the fuel flow based on the difference between the desired and measured pressure values.

4. How do you test a fuel pressure switch?

To test a fuel rail pressure sensor, you can use a multimeter to measure its output voltage. Start by turning off the engine and disconnecting the connector from the fuel rail pressure sensor. Then, connect the multimeter's leads to the terminals on the sensor, one lead to ground and the other lead to the signal terminal.

5. What happens when a pressure switch fails?

When a pressure switch fails, the furnace may shut down and attempt to restart several times. If the pressure switch doesn't close after multiple tries, the control board will stop sending voltage to the inducer motor, preventing further attempts.

6. What happens when a fuel pressure sensor goes bad?

A faulty fuel rail pressure sensor can lead to inefficient fuel combustion, resulting in engine knocking, rough running, and potentially engine stalling. It can cause either a lean or rich fuel mixture, affecting the overall performance of the engine.

7. What controls the injection pressure and timing in a unit injection system?

In a unit injection system, the pressurized delivery of fuel is driven by the camshaft. However, the timing of the injector's internal operations is controlled by the engine control unit (ECU) for optimal performance.

8. What component controls the pressure in the fuel injection system?

The pressure in the fuel injection system is regulated by a pressure regulator. Any excess fuel that exceeds the desired pressure is returned to the fuel tank via fuel lines. Generally, the fuel system in this type of engine operates at low pressure.
