The document discusses signs of a bad fuel pump relay in an Audi A4. Some signs include the engine stalling suddenly, not hearing the fuel pump noise when turning the ignition on, the check engine light being activated, the engine becoming dead, and rough acceleration. A faulty fuel pump relay can cause issues with the fuel pump power and proper fuel delivery and pressure to the engine. It is recommended to bring the car to a mechanic to replace a bad fuel pump relay.

2. The fuel pump relay is an important
component of the fuel system of the
car.

3. It gives power to the fuel
pump when it is time to build
up fuel pressure in the rail.

4. Whenever you turn on the
ignition of the Audi, the fuel
pump relay is turned on.

5. There are different reasons due
to which the fuel pump relay is
failed.

6. The following points define the
signs of bad fuel pump relay in
the Audi A4.

7. ENGINE STALLING

8. If the fuel pump relay is failed, it
might suddenly lose the relay
connection.

9. Engine turns off if the combustion chamber’s fuel
doesn’t have the proper pressure.

10. NO NOISE FROM A
FUEL PUMP

11. When you turn the ignition
on in the ignition lock, you
should hear a whirring
noise.

12. If you cant hear this, there might be a
problem with the fuel pump relay.

13. ACTIVATED CHECK
ENGINE LIGHT

always monitors all engine sensors.

15. If the ECU suspects a wrong
value from any sensor, it will
light up the check engine light.

16. DEAD ENGINE

17. A faulty fuel pump relay can cause engine starting problems
and make it dead.

18. Due to these reasons, it
would not give any power
to the fuel pump to build up
fuel pressure.

19. ROUGH
ACCELERATION

20. Bad fuel pump relay can affect the fuel
pump's power and fuel delivery to the
engine.

21. Moreover, it will affect
fuel flow to the
combustion chamber and
cause starting problems.

22. CONCLUSION

23. Diagnosing the failed fuel
pump relay in Audi A4 is
time-consuming and
stressful.
