Reply To: Crank but no start, ecu? – GV250 2012 EFi Feb 15, 2023 at 3:07 AM #9650 Jason👤 Member Topics: 3Replies: 28 If the 250 is similar to the 650 they are triggered by the ecu to ground.  The yellow spark is most likely low voltage. Do all the regular checks, resistance of stator, resistance of pick up coil. Can you short out the dealer plug to get a code?
