Clutch Switch

Issue with starting the car. Starter was already changed, eliminating other culprits.

Could someone please tell me where this part is located on my 2002 MCS?

Check #4 above first. It's located on the clutch master cylinder attached to the clutch pedal inside the car. It's an ignition lockout switch and must be attached to the clutch master cylinder in order for the car to start (they can become disconnected). It's also possible that this switch is defective and causing your no-start issue. The switch is only ~$23.

Have you tried jumping the battery with another car? If it jumps and starts then your battery is suspect. Your battery, though not old, could have a dead cell. First task is to have it tested. MINIs are notorious for having problems with a weak battery. Testing is free at AutoZone, O'Reilly's, etc.

Thank you for the advise, I have a tester checked it a couple weeks ago when issue presented itself and it was in the green, will check again. Just rolled it down the hill popped the clutch and still did not want to turn over, that is a 1st for me.

Update: The car started consistently once the battery ground wire was cleaned and lubed. Thank you all for helping me out,
