I have a big boss 6x6 500 polaris. this winter I first threw a voltage regulator then fixed that. then the next wknd I froze thye thing up and had to put it in the shop and thaw it out, put new gas in yada yada, anyway now the thing will turn over great with electric start but absolutely will not fire and as soon as I pull the rope it starts imediately.I'm thinking a week coil someone else said a badd fuel pump, I don't know I'm looking for some opinions, thanks

I've had a weak battery give that symptom. Will crank and crank, one pull with the rope and it starts. Sounds wierd but check that out.
