Help with a C41 Error


This is on a dragbike. GenII ECU.

When the ignition is turned on , I get the fuel pump relay active for about 2.5-3 seconds and then it gives me the C41 error..

What does the ECU need to see to make it fuel pump happy?

Check side stand switch...also check your ignition switch and make sure your ecm connections are tight..and you're not losing power on pin 16 at the ecm...check all your gnd.
