I'm hoping to get some ideas on this issue, and yes, I have used the Google custom search extensively with no close matches. My 2003 Sport 3.9L has almost 90k miles and is always driven in the summer, and stored covered with a battery tender in the winter. That was the case this time, and the last time I drove it was around Thanksgiving and started in December. Living in Michigan we have had some extreme low temps, but the car has not started through those.
Yesterday I removed the tender, started it and moved it into the garage for the next morning. I let it run for close to a half hour with the auto climate set to 70, and when I returned to shut it off, all seemed fine except for the slight odor of antifreeze coming from the vents, which is probably a leaking heater core and a separate issue.
When I returned this morning, ambient temps around 20F, everything was normal. All of the cluster lights, dome lights, and door chimes were normal. The battery was around 12.5, which I know is slightly below where it should be. However, when I turned the key to 'start,' I only get an audible click from under the hood. It isn't a constant clicking that one would associate with a low voltage crank, just a single click that almost sounded like the starter solenoid engaging, but no cranking was heard. I tried this with the transmission in both Park and Neutral. I even hooked my large Snap-On jump box up for good measure, with no change.
Is there anything I'm missing here? Since I was running late for work at this point, I didn't get on the ground to look underneath yet, nor look at fuses yet.
