My car out of nowhere won’t start. It’s just got under half a tank of petrol. All the dashboard lights turn on, radio and headlights too, but the car is still struggling to start. Any guidance would be much appreciated.
Thank you.

The car cranks but won’t run. The engine light stays on but a can’t hear the hum from the fuel pump when I switch the ignition on either.

Welcome to 2CarPros.

Most times, it is either a fuel or ignition related issue. I need you to try something. See if starts for a couple seconds using starting fluid. If it does,. then it is a fuel related issue even though you hear the pump. If it doesn't, then it is ignition related.

Here are the manufacturer's specs for fuel pressure:

Fuel line pressure .................... 375 - 450 kPa [3.9 - 4.5 kgf/sq.cm, 55 - 65 psi]

If it doesn't start with starting fluid, check for spark.

Let me know what you find or if you have other questions.
