Forums 🚥 PiT STOP 🔧 Hyosung Technical Help GT650R Fuel Pump Fault Reply To: GT650R Fuel Pump Fault
It’s runs, and will idle but does sound a bit lumpy and sometimes will die if just left ticking over for say 5mins.
not tried a test ride yet, just had her running on the drive on paddock stand.
the looms is a replacement and I have done a continuity test from each location, so I know power should get to the ecu.
I’ve tried swooping over the relays with each other and no change (can’t see it being an issue with them all).
unplugged the white plug that goes to the injectors and air box and I get all the other usual codes including the c41, then when i plug it back in the rest go just leaving c41
Plan to throw some engine treatment (wynns) in the tank too as the bike not ran proper since 2018.
One thing which is odd is when I have the white plug disconnected so it shows the other codes it has a clear c, but when 41 is shown on its own it has a line above it. As in the photo below.
