I have a Exmark Lazer Z EPS with the 26EFI Kohler, up until a couple of days ago it ran fine. While cutting the engine bogged down(never happened before) and would not restart. The battery was a little weak so I removed it and recharged. The next day it would turn over fine but would not start. When you turn the switch on the electric fuel pump is not running. I know it is not getting fire to the pump, and have already checked the fuel pump fuse and relay, both are ok. Also checked the computer codes and it shows every thing is ok (Code 61)? Any ideas?
