I'd like to thank everyone who helped me get my Brick running again. It may still have a sensor issue, but it finally started.

I spent most of yesterday detaching and cleaning sensors to no avail by last evening (game called due to darkness). Most of them just had a coating of road salt on them, but I cleaned them anyway. I even checked all the fuses for good measure and to muse a while about the no-start puzzle--Had it suggested a problem that I just didn't pay attention to? Dad suggested it was a cracked distributor cap.

It was a balmy 29 degrees F this morning. I had arranged for a ride into town to pick up a cap and rotor this morning. Before I went to all the trouble of pulling the cap and rotor to make sure I was getting the right part though, I wanted to try one more time. I decided to reinstall the Volvo plugs since they were clean and dry (the NGKs probably got fouled by yesterday's last attempt--they did). Switched plugs, turned the key and--viola--it turned over, caught a tad roughly, compensated and ran so silently I thought it stalled. It was like it never had a no-start problem at all.

I let it idle for about 40 minutes just to let the dry gas get through the fuel lines in case there were some ice crystals in there (first thing I did when it wouldn't start after the cold snap). Began shovelling the driveway while listening for any strange behavior from the idling Brick. Intermittently after it was at running temps, it hesitated a hair but recovered smoothly each time (O2 sensor going maybe?). The hesitation was so subtle I doubt I would have noticed it if I weren't half-paranoid about it stalling. Any other make of car would be a full-paranoid, but I love Bricks. The real test will be starting it cold in a few hours.

I'm going to have my mechanic check a few things this week anyway, and give it a complete tune up which I had planned on within 1,000 miles anyway. At least he has a warm garage, which is more than what I had yesterday cleaning what sensors I could remove completely at my kitchen table to stay warm and those I couldn't under the hood in less than ideal wind chills.

Many thanks to all who replied!
