Check the harness, in particular the larger plug connections.
Honda's goofy design on the bike has several grounds and power wires linked togehter, even though they're for separate circuits.

Theres' a few other things that you can check.
Give me a call if you can't get it straightened out.

I've also got a meter assy. if you need to pull any codes.

ok i have no idea's whats up, i came home from work and decided to mess with it some more, as soon as i turned the key "on" the fuel pump primed and it worked like normal, it ran for about 15 seconds, and i decided to rev it up a little and it bogged like a cold carb'd bike then died. i then turned the key off and then back on and it was back to "fi" mode...i have no effing clue

ok... your relay has good supply but no output... what is the control? the ecu? disconnect the harness and check your grounds w a dvom to the negative battery post(voltage drop test.) Lemme see if I can find a schematic.

If this is accurate, should be helpful...

U checked ur usual cut offs, so lets work backwards.

1. no power to the pump, no power out of the relay... pin #25(blk at ecu) does that have power at the relay or ground? That is the command for relay activation from the ECU to ground the magnet, and allow contact for the output circuit. If there is power, the ECU is not providing a ground. If there is no power, there is either a ground(all power being expelled at the relay, or there isn't a power source.)

2. No power at the brown/blue wire at the relay, key on... check for power at both blue/white wires at the relay... they should have a switched power at the relay(backprobe, keep relay installed.) W no power, you need to chase back to the cutout relay

3. Check the fuse wire from the battery for power, the next(third from right) for power from the tip sensor, then finally the last wire from the start/stop.

Hope that helps...

A high resistant connection at one of the items that was jumped can cause that too... If it is a permanent problem it would be easier to find so dont look at it in a negative way; If it were very intermittent it would be a harder issue to diagnose.

Sweet! Got it down to being just the ignition. So were going to switch ignition setups and it should be good to go....
