I have an 02 800 mtn cat EFI and it has a newer fuel pump. Now it does not start outside in the cold (4 below) when I am 150 miles away from my house and ready at the trail head! With the EFI is it possible to have a fuel water filter somewhere, or something else that is cold related that does not let me have my fun?? I have been reading the forms on the fuel pumps and I will try the jump start method tomarrow. I do know that I did not smell gas on the spark plugs and it did fire over for about 10 seconds when I manualy put fuel in the cylinders. I have cut out all the cuss words I let out at the trail head ( leading to big powder on a blue sky day). Help please.......ps, the sled does start in the garage just fine, which is where i spend most of my mountain ride time latley.
