my altima won't start, i think it might be cold weather, could that be possible?
what can i do?

 

Cold weather does have that much affect unless you have a carberator. I have had the same problem in the past in my dodge avenger, it turned out a few days later that my water pump went out and the timing belt. But it could be several things. Do you know for a fact that it started when it was warmer out side?...Cold weather has alot of effects on vehicles. The radiator fluid could not be tested reguarly and it end up going bad (not keeping the coolant from freezing). Also, a reason it may not start is because of a blown head gasket.

 

Question---Does the engine turn over? Fast or slow?
Need more info.
