How to troubleshoot a Vauxhall Corsa that won't start?

I have a 2008 Vauxhall Corsa and recently it won't start. The engine turns over but it won't ignite. I checked the battery and it seems fine. What could be the issue?

First, check the spark plugs. They might be dirty or worn out and need to be replaced. Also, check the fuel filter and the fuel pump. If they are clogged or malfunctioning, they can prevent the engine from starting. If all else fails, it could be an issue with the ignition switch or the starter motor.

I had the same problem with my Corsa. It turned out to be a faulty crankshaft position sensor. It was a simple fix and relatively inexpensive.

Check the car's immobilizer. If it's not recognizing your key, it might be preventing the car from starting. You can try resetting it by disconnecting the battery for a few minutes and then reconnecting it.
