i was just wondering if somone could help me i have a 03 polaris trail blazer it will start with the rope but not the key (if i crank the hec out of it some times it will start ) new battery plug fuel filter cleaned all the conectors

 

How fast is the starter turning it over? Did you check the compression, sometimes when it is low it is hard to start, how good is the fuel, and lastly spark plug gap?

make sure there is good connections and try pulling the plug out and crank it over to see if your gettung any spark.

 

there is spark fresh 92 octain gas good compression and gap is good if i unplug the ignition and let it sit over night plug it back in the next day it will start twice with the key then it wont anymore i have done that a few times and it is the same everytime thank you for your info but have alredy tryed all that if anyone hase any other ideas please help runs grate after started

 

Cranking the motor will draw the battery voltage down (and any questionable connections will only make it worse). Lower voltage = weaker spark. Pulling the cord does not place a load on the battery, hence higher voltage and a stronger spark. If indeed you are sure the connections are all good, I'd start to give the battery the evil eye, even if it is new. Stranger things have happened. But a bad connection at the battery (+ or -), bad cables/crimp connections or connections at the solenoid seems to me to be the most likely culprit.
