So where would you start? The past couple of times I got in my van and
cranked it up, the engine would barely turn over, but after two or so
revolutions it started. Until it didn't. I have one of those cigarette
lighter volt meters and after sitting overnight it reads 12.6 volts. When I
turn the key to crank it, it doesn't drop below 11.5 volts or so. I put a
trickle charger on it just to be sure, but it still won't start. Currently
I hear no noise whatsoever when I turn the key except for the fuel pump
priming.  Before this started I regularly watched the plugin volt meter and
while running it stays at or over 13v. So I'm pretty sure it's not the 1.5
year old battery or the age unknown alternator.  I assume that's a safe
assumption.  If you disagree I'm all ears. So if it's not the battery,
would a bad connection be the next most likely place to look and if so
where?  The only place I've checked out so far is the actual battery which
shows no signs of corrosion at all.

Thoughts?
