Won't turn over
My Chrysler 300 won't start it just makes a click sound and
that's it but we put a switch to the starter and it would turn
over but won't stay on the battery is good the fuel pump is
good the relay is good any help please!!
Check the connections to the battery and make sure they are tight ( and make sure black to negative and red to positive) if that doesn’t do it check the ground for the starter. The starter could also be bad, based on the fact that is won’t stay turning, you can take it apart to clean and grease the internals of it.
That click you hear is a defective starter/solenoid. Replace them.
