- June 24, 2014, 18:31:36 PMI have colored the pertinent circuits. If I read your message correctly, the bike will run if you put power to the fuel pump.
The computer relies on a signal on pin 5 to tell it that everything is correct. If the pump does not run with the key, there can only be a couple of possible problems. Sure, the computer could be bad, but these are pretty robust, so that's like the last thing to worry about. There is no point in running the self diagnostic program, the computer will not set a fail code until the engine starts. You can rule out the tip over switch, too. That kills the spark, and you have spark. Check the GROUND to the pump....There is no "fuel pump relay" as such, it uses one main DFI relay to power everything.

- June 24, 2014, 12:47:39 PMWell I ordered a new ignition switch for my 2001 drifter because it wouldn't start. I turns over fine. Lights come on. I ran a positive to fuel pump it comes on. Any ideas past this ?
