Q: Put a new starter and battery and still won't start

asked by on

I just put a new starter and battery on my car and it still won't crank
My car has an automatic transmission.

With a fully charged battery in good condition, and the immobilizer (security) system off - check to be sure the immobilizer is not activated - if the starter motor does not operate at that point, there are only two possibilities: 1) either there is no power to the starter motor/solenoid, or an excessive voltage drop, hence the entire starter circuit would have to be diagnosed; or 2) there is power but the starter/solenoid itself is bad. If you desire that a specialist from YourMechanic determine which of these is the issue, and get it resolved, please request a no start diagnostic. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
