I'm so stumped. No power to the Fuel pump

I'm so stumped. 06 LTR fully built MX quad, no battery with the yosh kicker, yoshi PIM, and Yosh harness. No power to the injector or fuel pump. I got a new voltage regulator, tried jumping the capacitor, tried bump starting, and tried swapping the relays around. When I kick it and I have my yosh tuner hooked to the PIM the backlight kicks on, so it has power. I cleaned the whole fuel system. What else could it be? PCM? TPS?
Also If i hook up a 9V to the fuel pump it builds plenty of pressure and the FPR cracks open, also If i touch the 9V to the injector it opens as well. Theres just 0 power to them.
Where are all the fuses as well? harness is stripped and I only see the one next to the capacitor and the fan.

I did not think you could run a LTR without the battery unless you convert to carb. The fuel pump is turned on by the ECM and the ECM controls the injector. No power to the ECM then nothing will work. Also if the ECM thinks there is a critical issue it will not allow the bike to start and since you don't have a battery there is no way to know. Now if I assume that the bike can run without a battery and everything is clear in terms of errors that can cause the ECM not to allow the bike to start, then I would check your stator and make sure that is working properly.

The battery is not needed when going to kick start. that is one of the advantages. It uses the capacitors instead.

Good to know, thanks.

In that case, I do not know what all is involved to do this conversion but since the ECM is controlling the fuel pump, I would check and make sure that it is getting power, then I would make sure all the sensors are reading properly and I would start with the tip sensor as this will kill the fuel pump and not allow the bike to start.
