Can someone tell me if the electric fuel supply pump runs all the time when the key is in the on position?
I seem to recall it shutting off after a short time if the engine wasn't running. Mine is currently running all the time. The unit is a 2017 with just over 600 hours.
I found another post from 2021 with the same symptoms but no mention of it shutting off with the key on
. He reported it was the pump. I don't want to throw parts at it or drop 150.00 on a pump if the issue is elsewhere.
I'm asking as it occasionally hiccups as though it's not getting enough fuel. This happens when mowing up a steep hill or mowing a similar hill sideways.
It is very inconsistent / intermittent which is always fun to diagnose
. It's also not repeatable.
I know there are several safety switches that could cause the issue as well. I can jumper them but the fuel pump question may be an indicator of a pump going south so I'm starting with that before I chase my tail.
Might this also be a common failure ? Messicks has 2 in stock so ?
