2000 polaris trailblazer wont start please help

[redskinjoe]

I baught my daughter a 2000 polaris trailblazer, rode it about 5 times, replaced the spark plug, took it out once about 2 hour into ride it just shut off. i topped off oil for the oil injection, filled the gas tank, and still nothing.It has spark, and you can smell the fuel if you steady try to turn it over.It was running great when it shut off. If you have any ideas please feel free to post it.

You need three things to get an engine to fire. You need spark, fuel and compression. You said you have spark and smell fuel. I would check the compression. If you have low or no compression. I would check to see if you didn't break a reed. If not you need to tear down the top end.

I 2nd the motion.
Check reeds first then compression.

Polaris also have a wire or part that is known for breaking which will prevent it from starting.

There's lots of those on a Polaris.

Parking brake switch is common for no crank but he has cranks but no start/run.
50/90cc tethers stick open not sure about the trail blazers. The wrong tail lamp bulb in a Magnum will fry the brake switch and starter switch.

Some one here has to know....

Make sure the air filter is clean.. My old honda and even my lawn mower wouldnt crank because the air filter was soo dirty it wasnt getting enough air.. take it out and clean and try that... if thats the case the it was a simple fix.
