Customer bike came in with no fuel pump > turned out to be bad diode. No big deal. Now the fuel pump will not stop priming, but it is actually shooting directly into the intake and filling the oil with gas.... here's what's been done so far.

1. Swapped complete throttle bodies
2. Ecu swapped to another, now the bike doesnt do anything...
3. Swapped crank position sensor
4. Fi harness and relays swapped
5. Swapped engine harness
6. Swapped complete harness (running out of ideas)
7. Swapped fuel tanks
8. Swapped injectors and rails (totally different set)
9. 3 pressure regulators......
I really want to fix this bike but no matter what i do the problem persists...

 

Swapped another wiring harness and it worked. Gonna try and figure out the problem with the old harness.
