Sorry my poor english! When I press start button the bike won't start. Fuel pump isn't running and it gets no spark. We put on/off switch to the ground wire that goes from ecu to the main power relay and it started working. It still isn't working like it should but it runs. We tried new relay but it still wont start without the switch. Why isn't ecu giving the ground signal to main power relay? We tried 250 sx-f ecu but still nothing. I know it's not the same ecu as 350's but some one said that the fuel pump should work and it would get spark with that ecu. But like I said it didn't.
