If you're having fuel-related issues, such as:
* Engine won't start: The problem could be the fuel pump, fuel filter, a faulty fuel injector, a bad ignition system, or many other things.
* Engine is running poorly: Similar issues as above could be the cause.
* Check Engine light is on: This indicates a problem detected by the car's computer. You'll need to have the codes read using an OBD-II scanner.
You'll need to diagnose the problem using other methods. This might involve:
* Checking the fuel pressure: This requires specialized tools.
* Inspecting the fuel lines and filter: Look for leaks or blockages.
* Using an OBD-II code reader: To determine the specific fault codes.
Taking it to a mechanic is usually the best course of action if you're not experienced with car repair. They have the tools and expertise to properly diagnose and fix the problem.
