fwiw, the last trouble i had, my load tester
was miles away. there is an auto zone store
2 blocks away so i took it there. dilbert
the parts boy sez sir your battery is kaput.
i knew that was wrong so as soon as i could
access my own test equipment i found my alternator
was no good just like i thought it was. new
alternator fixed me right up. i've also had
to look up my own parts because they didn't
have the slightest clue what i was talking about.

a free diagnosis is worth exactly what you
pay for it

sorry, no helpful hints as i have no experience
with those kind of frigid temperatures. i can
say for sure that the gas we buy these days
is about half water and half pee.
was the pump pressure at the rail in spec ?
