You need to put it on diagnostics and get codes, and check battery 12.3-4 volts

Should be a minimum of 12.6 volts.

When you say it will not start, do you mean it does not crank or it cranks but doesn't start? A low battery will cause all sorts of problems.
The ignition switch is a known failure item on some L322 models

Fitted new battery and ignition switch still the same

But still check battery, they are not always fully charged when you get them, then you can eliminate it

If it will not crank, it points to an electronic problem, the only way forward is diagnostics.
If the battery is new and it cranks after leaving it for 2/3 hours the battery is unlikely to be the problem. Batteries lose power with time.
You could look for water ingress anywhere but particularly in the nearside rear quarter.

Have a check of the engine earths, they are known to give grief.
