Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologize for any delay.
Dear customer, I am sorry that you are presenting these problems with the ignition system, to give you an answer with basic concepts your vehicle is not starting due to problems in the starting system or the battery power is not adequate.
When the battery is worn, it does not have enough energy to turn the starter motor correctly, therefore the vehicle cannot start correctly, I understand that the battery is fine but it is good to try with another battery since even when it has the load cells may be worn or damaged, that is why you may be presenting error codes regarding the alternator signal.
If the problem persists once the battery has been replaced, it is very likely that you will need to service the starter motor or you have not performed maintenance there for a long time, a starter motor has internal moving parts which are highly lubricated to be able to turn the starter motor with enough force. With the passage of time you can present lubrication problems which causes the starter motor to stick, for this vehicle does not start.
And finally, you may be presenting problems in the starter motor relay, the starter motor has a relay which is the one that gives the energy to turn when the relay does not work, you can hear a ticking noise but there is not ignition, that noise is also characteristic when the starter motor is stuck.
These are the aspects that must be verified, dear customer.
My goal is to give you the best advice i can, I hope to be helpful, if you have any doubt or want to know anything else please do not hesitate to reply back.
Kind regards, Sebastian.
