I have a 2007 LTR 450, and it won't start. It only started doing this in the past few days. When I turn the key over The fuel Pump primes, but very very quietly and it sounds like a sloshing sound. You need to get your ear right up to it to hear it. The pump Plug is getting 12 volts so there's no problem with that. The pump was replaced a few months ago, it worked great when it was brand new, and then it started only priming sometimes, now it does that quiet sloshing thing. I'm trying to sell this quad and need to get this fixed asap. Thanks.
