I ****ed up today...
and, like a rookie, hooked up but damn battery backwards.
It blew the main fuse but with me putting power to the rest of the electrical via my handy power probe (if you don't know what it is look it up it's a wonderful tool) I was able to make it run. I'm pretty sure but not positive the fuel pump was priming at this point. (It may just have been running off of the pressure in the lines)
I replaced the fuse and everything seems to work but the fuel pump won't prime and the bike won't run.
I can manually power the pump and it runs. The pump relay does work. The signal wire to the pump (Brown w/black tracer) is getting battery voltage. By grounding this wire it switches the relay and the pump runs.
This leads me to believe that my ECU isn't grounding the signal wire to the fuel pump relay. What besides a faulty ECU could cause this??

i think you should just be able to test the voltage of that pink wire running into the ignition switch and it should read 9v when you turn the key on. The red one should be getting 12v. If the pink wires getting 12v then theres your problem. At that point id take off the ignition and check the voltage across the diode just to make sure. If thats not your problem then all i can say is go over the wiring diagram and check out any other possible fuses that could be blown that would prevent the pump from priming or other grounds that there could be a problem with that could be causing it as well.
