700sci fuel pump doesn’t turn off
Hey guys,
on my 700s the fuel pump stays on even if ignition is off. The only way to turn off the fuel pump is to switch off the power through the battery switches.
Should I replace the whole pump or if I was to fix it where should I start..
‘Thank you

Ive never worked on a 700 but there should be a fuel pump relay mounted at the rear of the engine, maybe its stuck in the energized state
