Its a 2002 arctic cat zr600 efi with only 750 or so miles. It has sat for 6 years without running, and with old gas in it. The tank has been cleaned and we blew out the fuel rail. It will sometimes start and run for about 5-10 seconds, and now it wont do anything at all. It has great spark. Any ideas as to what could be the problem? Fuel injectors maybe? I have heard that the crank seals could have dried out by now, but hopefully that isn't the case. Any advice? thanks in advance
