Having trouble starting
 

The "wait to start" light has been taking much longer to click off, then the truck started having issues starting. Turn the key several times and get an audible click but no start. It will finally start after turning the key multiple times. I replaced all the battery cable ends and that fixed the hard to start issue momentarily. It's doing it again and the "wait to start" is taking forever to turn off, even when the truck is plugged in. Are these issues related? Any ideas on what it could be?
