Why is my Vauxhall Corsa's engine not starting?

When I try to start my Vauxhall Corsa, the engine doesn't even crank. I've checked the battery and it seems to be fine. What could be causing this issue?

First, I would recommend checking the starter motor. If it's faulty, it can prevent the engine from starting. You may also want to check the ignition switch and spark plugs for any potential issues.

Another possible cause could be a fuel pump failure. If the fuel pump is not delivering enough fuel to the engine, it won't be able to start. You can try replacing the fuel pump or having it checked by a mechanic.

It's also possible that there is an issue with the fuel injectors. If they are clogged or malfunctioning, they can prevent fuel from reaching the engine. A professional diagnosis and cleaning may be necessary to fix this issue.
