The fuel injection system delivers fuel to the engine and is regulated by a computer using sensor data. Malfunctions can adversely affect engine power output. Problems starting the engine or causing misfires, check engine lights, poor fuel economy, or emission issues may indicate issues with the fuel injectors that should be addressed. Fuel injectors play a vital role and errors can have serious consequences.

2. The primaryjob of the fuel injection systemis to deliver fuel to the engine.

3. In modernvehicles, the fuel injection systemis regulatedby a computer.

4. The computer uses data from different types of sensors located in the
engine bay or inside the exhaust system.

5. Then, inject a calculatedamount of fuel into each cylinder of the engine.

6. Fuel injectionsystemhas been differentiatedinto two broad categories:

8. Malfunctions in the fuel injection system could affect the power output of
the engine in a very adverse way.

10. STARTING PROBLEMS

11. An engine won’t start in the absence of an adequate amount of fuel inside
the combustionchamber.

12. This happens due to the inability of the fuel injection system to deliver the
required amountof fuel to the engine.

13. Facing problems while starting an engine should never be ignored as it
could lead to a serious problem.

14. ENGINE MISFIRE

15. The engine control unit regulates the timing and quantity of fuel injection.

16. However, clogged or faulty fuel injectors could not fulfill the requirement
of the engine whichcould lead to the engine misfire.

17. Besides, a sudden drop in RPM is also a warning sign of a deformed fuel
injection system.

18. CHECK ENGINE
LIGHT COMES ON

19. Needless to say that any kind of malfunctions in the engine might trigger
checkengine light.

20. Although it could refer to a vast array of mechanical errors, a deformed
fuel injector might be the one.

21. Besides, a sudden drop in power generation by the engine accompanied by
the illumination of check engine light indicates that the fuel injection
system has some errors.

22. POOR FUEL
ECONOMY

23. An abnormal fuel injection system could overlook the commands provided
by the ECU.

24. And it could inject an excess amount of fuel into the combustion chamber
of the engine.

25. So, a sudden drop in fuel economy along with the reduction of power
generation by the engine indicates that the fuel injectors have some
problems.

26. EMISSION
RELATED ISSUES

27. Injection of an excess amount of fuel into the combustion chamber might
trigger several emission-relatedproblems.

28. Emission of thick black smoke shows that the emission system or the fuel
injection systems havesome deformities.

29. Presence of a huge amount of unburned hydrocarbons in the exhaust
gases also a clear signof a failedfuel injectionsystem.

31. Fuel injectors play a vital role in the process of power generation by the
engine.

32. Errors in such crucial components of the car could have disastrous
consequences.

33. So, signs which show that the fuel injection system has problems should
not be ignoredand timely action should be taken to fix suchproblems.
