Having a strange no start issue with my 2009 FSE450 Gasgas. Was running great, till I pulled the motor to clean the engine and frame and fix some rust on the frame. Did some welding on the frame, but I removed the ECU before starting. Put it all back together after some minor engine work,(new water pump seal) and she cranks over like a champ, with good spark, but won't start. I've isolated the issue to the injector not getting a signal to fire. It'll fire on ether for a few seconds, but wont run on injector. Fuel pump is fine. Triple checked all connectors as far as possible and all looks good. Any ideas??? Can't find an English workshop manual anywhere online.
2009 450 won't start.
