Having trouble getting my ksf running when i pull start it it only runs while in motion an in gear.need help
Clarify..Does not start when motor is cold or hot...??

Make sure the battery is fully charged 12.8 volts standard...!!

Does the F.I dash light remain ON or flashing when trying to start..??

Make sure the throttle cable has a little slack in it to allow the butterfly to completely close

Check the vehicle down sensor to be positioned & working...

Check the TPS/throttle positioning sensor to be in range...0.58~0.62v DC @ close & 3.7~4.1v DC @ WOT
sensor adapter part# 57001-1538 is recommended for this test

see pictures below
