Another thing to check are your plugs. Are they the correct ones for the engine? I had some serious problems starting my V-8 at below freezing temps (teens) a couple of years ago in South Dakota. When I got back to Texas I eventially found out that the Toyota dealer that did my 90K service for me installed the Tacoma V-6 Denso plugs instead of the Tundra V-8 plugs. They also used Type IV ATF instead if DEX III in the tranny too, but that's another story! Anyways you might want to check your plugs.
