I have a 1995 Polaris indy 500 efi. This machine has always been a good starter. It still starts good, but after 5-10 minutes of riding it dies and it won't start after that. I changed all the fuel line and clamps, I can hear that the fuel pump is running and I changed the fuel filter, fuel tank is clean. If you have another suggestion I would appreciate it. Thank you Marc

SOURCE: there is no vacuum at the fuel pump. i replaced

Have you checked the fuel lines in the gas tank? Sometimes if the pickup line gets cracked it will **** air and no gas. give this a try. Good luck let me know.

Wait, it just wont turn over, like the engine won't rotate?, that is either a broken crank, which not unusual for those 500's or you seized it, (welded the piston to the jugs). if this isn't what you mean, and it will turn over but not on its own power, then either your jets in the carbs are clogged, fuel may get to it, but not through it, or your rings are stuck closed and giving you low compression, check this by pulling it over slowly, you should feel each piston completing the revolution with a prominent glug glug. grab your primary clutch and rotate it back and forth, it should have a bit of play, but if it clanks and has alot of play, your crank is busted

SOUNDS LIKE THE ENGINE IS BADLY FLOODED, SHUT YOUR GASS OFF AND REMOVE THE PLUGS, THAN PULL IT OVER UNTIL IT IS UNFLOODED. IT SOUNDS LIKE THE NEEDLES ARE STUCK IN YOUR CARBS
