question on starting
 

Hello board,
I have a concern about E420? If the battery is going bad would it effect the operation of the radio. Or vice verse. Sometimes the car won't turn over. It would seem to be the ingintion switch or a bad battery. After a few times of key turning the car will start. Any suggestions.

have the battery load tested at a local parts house, check the terminals for clean and tight, then look at ignition switch. poor battery connection are the #1 cause of poor start conditions.

hello board,
I am re-posting the message. I still need our collective knowledge on this one.
