Unable to start

Thanks for the advice.
I was able to get spark in the spark plugs. As far as I can tell the fuel pump did work. I was also able to notice the battery did not hold much of a charge even after sitting on the charger all evening and all we did was try to start the vehicle and listen/watch to see what was happening. And even tried to boost again. The battery does appear to have some ice on top of it. It is -40c outside today and has been for the past several days. Could that be my problem? Could I have drained it too much and screwed the battery up before I got a charger back on it? I have a newer battery which I plan to try and see if the battery is an issue.
As for being able to check the fuel filter I am not even certain where it is. Another thought that came to mind is there a possibility of when we tried to start it the other day - could we have flooded it and it got into the oil and not getting any friction when we crank the motor? Which would mean changing the oil or is there a simpler way to check that. We did look at the dipstick and it looks normal.
We are more convinced though the timing belt slipped the last time I had it running.
Let me know what you think about this and other suggestions you may have.

I just took some time to check to see if my block heater was working since it is so cold. It turns out my block heater is not working and I was wasting time thinking/believing it was. I do believe with -40c to -50c temps right now my vehicle is just frozen. I have made arrangements to get that changed immediately.
