My Mazda CX-3 won't start, but the battery is fine.

Check the starter relay and fuses related to the starting system. A faulty relay or blown fuse could prevent the starter from engaging. Let me know if this resolves the issue or if you need further assistance.

Hi I've checked the relays and all fuses and everything was in order

(Translated from Norwegian)

Inspect the starter solenoid connections for any loose or corroded wires. A poor connection can prevent the starter from engaging. If the connections are secure and clean, the issue might be with the ignition switch or the wiring to the starter. Let me know how it goes or if you have more questions.

The relay doesn't even click when the ignition is turned on, I'm sure the relay is fine. But I have to press the ignition lock twice now, and before it was only once, so the problem most likely lies in the ignition system?

Yes, it sounds like the issue might be with the ignition switch or the wiring connected to it. Check for any signs of wear or damage in the ignition switch and its wiring. If the switch seems faulty, it may need replacement. Let me know if you need further guidance or if you have any questions.

I've received a diagnosis and got the error code U3006:16-0F control module input power a circuit. Where could the fault be?

(Translated from Norwegian)

The error code U3006:16-0F indicates an issue with the control module's input power circuit. This could be due to a poor connection, damaged wiring, or a faulty control module. Start by inspecting the wiring and connectors related to the control module for any signs of damage or corrosion. Ensure all connections are secure. If the wiring and connections appear fine, the control module itself might need further inspection or replacement. Let me know how it goes or if you have more questions.
