I have a 2003 Polaris trail boss that has no power what so ever... I have a new solenoid,key switch what else could be wrong with the ****....no battery but I’m I have a jumper and it still has no power..

 

Have you tried providing power directly to the starter to see if it turns?

 

I have a trail boss 330 good compression good spark and getting fuel but will not start. Have tried a few things to no avail. Could it be the crankshaft sensor that is giving the wrong signal for it to spark at the wrong time
