How do I troubleshoot a faulty fuel pump in a Vauxhall Insignia?

I've been experiencing issues with my Vauxhall Insignia's fuel pump not functioning properly. It starts up without any issues but after a few seconds, it starts to stutter. What could be causing this and how can I fix it?

First, check the fuel pump fuse and relay to ensure they are not faulty or blown. If they are fine, the issue could be with a clogged fuel filter or a faulty fuel pump itself. It's best to consult a mechanic for a proper diagnosis and replacement if needed.

Another possible cause could be a weak battery that's not providing enough power to the fuel pump. Try jumping starting the car, if it starts and runs smoothly, then it's worth getting the battery checked and replaced if necessary.

Older cars tend to have issues with corroded wiring or loose connections. Check all the wiring and connections related to the fuel pump and clean or tighten them if necessary. This could solve the issue without any costly replacements.
