How to diagnose a faulty ignition coil on a Vauxhall Zafira Life?

I have been experiencing issues with my Vauxhall Zafira Life starting and running smoothly. I suspect it may be due to a faulty ignition coil, but I'm not entirely sure how to diagnose it. Can anyone provide some guidance on how to properly diagnose a faulty ignition coil on a Vauxhall Zafira Life?

First, start by checking for any diagnostic trouble codes using an OBD2 scanner. If no codes are present, the next step would be to test the resistance of the ignition coil using a multimeter. If the resistance is outside of the specified range, then the ignition coil is likely faulty and should be replaced.

Another way to diagnose a faulty ignition coil is to perform a spark test. Remove the ignition coil from the engine and use a spark tester to check for a spark while cranking the engine. If there is no spark, then the ignition coil is most likely the culprit.

I have had similar issues with my Vauxhall Zafira Life and have found that using a quality ignition coil can make a big difference. I recommend checking for any signs of wear or damage on the ignition coil and replacing it with a reputable brand if necessary.
