Two weeks ago, my car froze due to several days of below zero temperatures.  I have a 2008 Torrent GXP with a V6.  We replaced the battery and the starter, put in new plugs.  It's in bad need of an oil change, which we will get, but can't get the plug out to drain it so we will need to take it in (need air tools)  While replacing the starter, the exhaust had to be lowered and when putting it back in place, I was told we needed new bolts and a new exhaust manifold gasket to be replaced.  The gasket and bolts have not yet been replaced, but should they be a reason the car won't start?  It turns over and fires, but won't stay running.  (I think that's the right way to say it).  I've only owned this vehicle for a year, it's got just over 170K miles on it.  Before it froze, I had no issues with this car.  I just dont know if what I'm dealing with is a simple fix that we haven't tried yet, or if it's time to find another vehicle.  Any insight or suggestions are greatly appreciated.  Thank you.

If the gas tank was low on gas when this all started, the probability of gas line freeze goes up. In extreme cold weather like we've had here in the northern midwest, it's best to keep half a tank of gas or better, whenever possible, when you leave a car or truck outside overnight.

I haven't had a chance to get anyone to look at the car again, but, I keep searching on line for the location of the fuel filter, because someone suggested that its in the tank....my car is a 2008 Torrent GXP 3.6L   where can I find a diagram or info on the fuel filter??  Sorry, I just know so very little about this stuff.

Okay - you are correct, I did some checking as well, the fuel filter on the Equinox/torrent/Vue platform is in the fuel tank. While it is not inconceivable that the filter is clogged, I find it unlikely. Clearly this will be an expensive endeavor to replace it if it is clogged.

In the engine compartment, along the fuel rail is a Schrader valve (similar to a bicycle or car tire valve). You or a mechanic should be able to check fuel flow by removing the cover to the Schrader valve and see if any fuel is flowing to the fuel rail when you try to start the car. That will validate that fuel is getting to the engine.

If fuel is getting to the engine, then we would have to diagnose the problem at the engine itself.

Have you tried to start the car with the weather getting warmer?

Yes and its starts and then dies right away.  This is so frustrating as this car had no issues before the deep freeze.  I know this is a long shot, but the oil was very overdue for a change, and is still waiting to be done....is it possible that this could be the cause?

I highly doubt that an overdue oil change could prevent a motor from running. A lack of oil would seize a motor up but doesn’t sound like the problem you’ve described.

Jill - Last Indian is correct. If the spark plugs themselves are not gapped correctly, the engine won't fire. The gap should be around .040. You can get a spark plug gap check/set tool at your local auto parts store for cheap. His point about the coil packs is also correct. 

Your car needs fuel, air, and spark to fire up. So let's take a "one thing at time" approach. Let's validate fuel first, them move to spark, we assume there is plenty of air at the moment.
