2007 Suzuki Swift engine not turning over

There are a few things to check here. The first is that even though the battery has been recharged, has it been load tested? This time of year is very hard on batteries and even though it may seem to be holding a charge, when you actually put a load on it via the starter motor, it can go weak at the knees and will not spin the engine over.

The clicking you can hear is probably the starter motor’s relay which controls the power to the starter. But what about the starter motor itself? Has this been tested for correct operation. Sometimes the problem can also be what’s called the throw-out mechanism which is a solenoid that forces the starter motor’s teeth to mesh with the engine’s flywheel teeth and, therefore, turn things over.

Perhaps an auto electrician is the best place to start. Their first job will be to test a range of things and rule out possible causes one by one.
