You may be thinking why you are visiting the gas station again and again; well, it may be due to several reasons. And the faulty fuel pressure regulator is one of them. Fuel pressure regulator regulates and controls the pressure that is supplied to injectors and engine. The regulator enables the engine to function optimally. When the regulator fails critically, it delivers poor performance of engine. Here in this slide, you will get to know the effect of this important equipment on your fuel efficiency and how to diagnose the issue easily.
6. Damaged Spark plug :- If you find out one spark plug is
damaged then make sure to check others and replace them.
7. If the tip of spark plug looks
blackened or sooty then it's a tell-tale
sign of faulty fuel pressure regulator.
8. Stalling or cold start :- If the fuel pressure regulator is
faulty then there will be a problem of abnormal fuel
pressure inside the engine.
9.
10. Emission of black smoke :- When you notice black smoke
coming from the tail pipe, then there is a problem in vehicle
as normally smokes should be white or gray.
11. A faulty fuel pressure regulator sends inadequate or excess
amount of fuel which causes improper combustion and
harmful emission in the form of black smoke.
12. Sometimes oil also leaks in tail pipe due to excess oil in
combustion chamber.
13. Decrease in engine performance issue :- The faulty fuel
pressure regulator always leads to lower fuel efficiency and
decrease in engine performance.
14. The improper air fuel mixture fails to deliver correct
amount of fuel to combustion chamber which decreases the
energy level to run the vehicle.
15. A faulty pressure regulator can cause seals fail and leaking
gasoline which ultimately decreases the vehicle
performance.
16. Sometime the engine oil also smells bad when fuel pressure
regulator is faulty.
17. The fuel pressure regulator doesn't fail very often but low
fuel pressure is sometimes the cause for it.
18. When fuel enters the vacuum
hose, it leads to problematic
engine performance.
19. You can check the fuel pressure by pinching the fuel return
line.
20. If the fuel pressure doesn't rise, then there must be a loss of
fuel.
