Recently my fuel flow stopped working, 0 would show on the mercmonitor gage. As a result the fuel used would not register either. The fuel used would always be inaccurate by about 20-25% low. Show 10 gallons used, fillup would be 12 gallons

My motor is 2012 115 EFI. I installed the Mercmonitor and engine sensors I purchased from Don a few years back.

Anybody have any info on what the problem might be? I know the fuel data comes from the engine computer so I am not sure if I need to have a tech reset the computer or there is some action I can take to get this data displayed again.

Thanks, Rob
