If you're experiencing fuel delivery problems, the issue isn't something you'll fix by pressing a button. Instead, potential problems include:
* Faulty fuel pump: This is a common cause of fuel delivery problems and requires replacement.
* Clogged fuel filter: A dirty filter restricts fuel flow. This needs replacing.
* Low fuel pressure: Could be due to a faulty pump, filter, or other components in the fuel system.
* Electrical issues: Problems with the wiring or the fuel pump relay can prevent the pump from working.
* Bad crankshaft position sensor (CKP): A faulty CKP sensor can prevent the fuel pump from receiving the signal to operate.
If your car isn't starting or running properly, you'll need to have a mechanic diagnose the problem. They'll use diagnostic tools to identify the source of the fuel delivery issue. Don't try to fix this yourself unless you have experience working on fuel systems (it involves working with potentially explosive fuel).
