That same relay control from the EHC supplies power to the ignition coil, the oxygen sensors and the fuel injectors.If I understand it correctly, the EHC provides relay power to the fuel pump through the EFI. The wiring diagram appears that it's just pass through. The EFI regulates the amount of fuel via the injectors. Since I don't get the pump to energize I'm assuming it's the EHC. The intermittent stumbling of the engine has never been caught by a computer hooked up to the bike. So I can only assume. But since I have the starting issue immediately after the engine stumbling issue, I'm assuming the power to the fuel pump is cutting in and out for a 1/2 second or so.
