Hi, I’m Ron and I’ll be helping you today.
Before we get started though, Please understand that I don't know
your skill level or tools you have to assist us. Also understand that
I can't see, smell, hear, or touch the vehicle either, so patience is
appreciated. JA is a great Q/A site, but it does NOT replace a
repair shop.
My goal is to make you happy and get a great rating in return for
my time. Sometimes I have to give you bad news that I know you
didn’t want to hear, so please don’t shoot the messenger.

Okay, let's start with doing a load test on the battery first. You can still have a bad battery but it has enough life in it to light up the lights etc. If that's good, then please check the cables for tightens and corrosion at both ends. Then check the starter.

Thanks, Ron
