Looks like starter motor is not engaging, can you hear a click from starter solenoid when key is turned into start position ?

No

Is it manual or automatic transmission ?

Manual transmission

If the starter motor is not responding to start request, this can be caused by number of electrical faults.
I'm happy to provide you with full troubleshooting instructions to find the fault.

OK. I have multimetered the battery. Reads 12.6v.

1.Check ground connection between engine block and battery negative terminal, use one of the jump start leads and connect one end to battery negative and the other one to metal part of engine block as close to the starter as possible.
Check starter operation
2.Access starter motor solenoid, check voltage between thin wire and battery negative while key is turned into start position.
If it shows 12 V, replace the starter motor.
3.If there is no voltage at the starter solenoid while key turned, remove the panel under steering wheel to access relay board.
Remove steering wheel cover to access red and black wire at the back of ignition switch.
Check voltage at the wire while key turned.
If 0 v replace ignition switch.
If 12V locate the relay with number 204 in the middle row, last one on the right(your car may not have one ) and check if relay is active.
If there is no relay and 12v is present at the back of ignition switch, investigate open circuit in this wire.
I'm happy to assist you further, if you have any more questions I'm happy to respond.

You're welcome, good idea, sometimes electrical problems are not easy and further checks must be done to find the fault.
