Very cold weather, started sometimes, then quit. Will not start now at all.

Welcome to the forum. Your question has to many variables. Cold weather out here in Cen Cal this time of year is mid 40s. Is the problem when the vehicle is cold as in ovrernight but starts ok when it is warm? Does it crank OK but seem like it's not getting fuel? If you hold the throttle slightly open, does it start OK?

Yes, my 2003 did the same with about 75k miles on it, stranded me on days it stayed under 40F unless I plugged in the block heater the night before, then it started like a champ. Dealer replaced the relay and a control unit under ESP warranty. There's no way to fix this one without throwing parts at it.

Tune up... its flooding when its cold due to the plugs being worn out...

I had a similar ongoing problem with my 1999 GMC Suburban C1500, it occurred only in the hottest days of the Texas summer. In addition to not starting, the truck sometimes exhibited symptoms of misfiring while driving at highway speeds, as if the engine seized or as if there no fuel being delivered to fire.
I found a small garage mechanic who swore he could fix it after years of taking it to the dealer and other franchise repair shops and getting the same answer "we can't find anything it like you described, it won't do it while we're testing it, bring it in right away so we can get the history codes....blah, blah, blah". I always thought it was due to an intermittent electrical grounding issue. Anyway, long story short, the small garage mechanic was guessing a lot of the time, but after changing the fuel pump, the sending unit, fuel injection system and many return trips to the garage with me saying 'that wasn't it, it's still doing it" it finally turned out to be a faulty wiring connector link in the harness assembly ABOVE the FUEL TANK that came from the pump or sending unit. When it got hot the link would melt and create a short, when it cooled a bit it would still conduct. We replaced the wiring connector and 4 years worth of unexplainable intermittent starting problems disappeared. I spent $2K to $3K over the years, when it finally turned out to be a hidden $12 wiring connector.
Good Luck.

What is the condition of the starter ? Is this an engine hard to turn over problem when hot ? If so, the starter might be grounding out, this happens only when the casing is hot.
