Another wont start issue :)

[cgalpha08]

So yeah, ive never had issues with the H3 not starting in the cold before, and its not even that cold, its around 40 degrees for the past couple of days. I go to start the H3 today, and nothing, wont even turn over. all of the electronics work, so there is enough juice for them but it wont start. Luckily i had an emergency starter pack that i hooked up and started the H3 with. After eating lunch for maybe 20 min, i got to leave and the H3 wont start again. Any thoughts?

A couple of things that i may think may be the issue but want your opinions on. I have an isimple and scanguage hooked up, and i have been having trouble with the electronics not shutting off when the door opens and the key has been taken out. But this all usually turns off in the next 10 minutes or so. Could one of these be draining my battery just enough that it wont turn over? or could it be something else thats even worse?

My H3 battery has not been drained of juice in atleast a year if not more, and it has never failed to start for me, even in winter weather, and the only variable that has changed in the past few days has been the weather. Thoughts?

A bad door jamb switch on your drivers door is reason your electronics are not turning off when you open the door. It should turn everything off after 20 minutes on it's own. They are about $14.00 at the dealer and sometimes you can find them on Ebay for $9.00 or so. Check your battery terminals, battery and alternator. Thats a good place to start.

So, the electronics turn off in about 20 min irregardless of the door jamb?

I will probably get a new one anyway, but just trying to isolate the cause.

I think 3rd is right on target. You may want to get your battery tested to see if it also worn out.

If your interior lights don't come on when you open the door, it is a bad switch. Test it vs the other doors at the same time

Ill check the lights but i have noticed that the electronics turn off when i open all the other doors except drivers.

Same thing. Bad door sensor. Buy a few and keep extras in stock. My second one failed days after replacing my first one

I always have spares because I broke one once getting out. Since it's a simple contact switch, you can get it to default shut by either unplugging it or grounding it, as a last resort.

New door jamb sensor/switch is on its way, we shall see what happens next.

Well now i am starting to get worried. I dont think the issue has anything to do with the door jamb. If i wanted to check the alternator and starter, im not even sure what to look for. The battery connections and all that are fine.

Have you had the battery tested yet? Any auto parts store should be able to help you.

Make extra sure on the battery connections. I had the same problem and thought my connections were fine but replaced the + clamp and that cured the problem.
