Will not start when weather is cold(north Georgia).

You did not say which Volvo. Is it a 240, 740... etc. Probably is one of those - so there is a 700/900 series faq @ The Volvo Resource: brickboard.com. Just use the dropbox where it says 'select shortcut' - upper right of main page.
Even if it is a 240 - the B230 4 cyl. Motors are all pretty much the same through most model years, so you should get an idea of what your problem is. If you can't find the answer in the FAQ's - get a username and make a post in the proper section.

Note. If you do have a rear wheel drive brick.. 200/700/900 series - there is an ace mechanic that works on older Volvos in Mt. Airy, GA. - NE of Atlanta.
