Hello, I have a Polaris 325 magnum 2000 model. It won’t start. I’ve cleaned the carb. Change the fuel pump put fresh gas in it cranks and turns over but won’t start attached video for some advice. Give it some gas. It sounds like it wants to start running, but it doesn’t. Starter fluid same thing.

 

you got this going yet?
Only thing you did not mention, did you check for spark by removing the plug.
could also be needing to let some fuel through if you just changed the pump.
