I have an Arctic Cat Prowler 550 with only 450 miles on it. It dies and won't start. It has good, strong spark. 42 fp fuel rail pressure. There are no codes on the meter; however, it won't run to tell me the codes. I suspect the tilt sensor and if so, where is it located. I have a manual but it doesn't say where it is. Is there a good reputable after market parts dealer in the country?
