    Yes, it will crank and not start. Check ecm fuse and wiring in battery box. Then I would separately isolate each battery. Load test individually.

    Well, you've come to the right place and it seems you're capable so far - and creating a thread that might help others down the line.

    Ok, well this actually makes me feel better. I did a lot of cranking before the repairs so I’m hoping this is the problem. The batteries themselves are new. Less than 5k miles on them.

    I'll add - I just replaced a full set of batteries after 13 months of service - Interstate warrantied them. A breakdown and no charging for 3 days in 15-20 degree temps killed them. They're normally either alternator/generator or shore power charged/trickled.

    Sometimes I get 2 years out of a set, this time 13 months. Always replace as a set, and consider replacing alternator at the same time. Cheap insurance for this time of year.

    “When I turn key to the on position the dash lights come on and then go off after it cycles. I’m stumped at this point.”

    Does the check engine light illuminate when you turn key on, and then go out?

    I probably will go ahead and replace the alternator in the next month or so. I was thinking about it.

    Yes
