My 1998 Honda VFR 800 sat idle for over a year, and now it won't start. The fuel pump isn't activating, indicating a potential issue with the ECU unit. To troubleshoot, I swapped in the ECU unit from my 2003 VFR. While the bike now starts, it lacks power and stalls after moving just 5 feet. The FI light blinks intermittently, and the RPM behaves erratically. When I loosen the fuel screw, the fuel pump pressure seems fine. Any assistance would be greatly appreciated.
