So, I took apart whole bike and put it back together. I'm not getting power to injector. I cleaned wiring harness when it was apart. Things I've tried already. Tip over sensor siliconeed, tried three different injector plugs, fuel is making it to the injector but not spraying when I turn the key on. The bike did fire up when I sprayed steering fluid in the intake. Fuel pump is coming on when I turn the key. Tps sensor is good and working as it should. 0.66 I believe was the number. Need help finding problem. Thanks in advance.

Hi bikelife, I am new to the ltr’s and mine in not getting power to the injector, I am lost. I don’t know much about them so I don’t know what to do. Have you figured out your problem? If so could you tell me what was wrong with yours and maybe tell me what to do?

I'm having the same problem except I'm getting votes to the fuel injector but I'm only getting 8 votes when I turn the key and the pump is priming and only 2 votes when I'm cranking the engine over, please if anyone has found the solution or knows of something we could check please let us know 🙏

did anyone figure out the problem? im having the same issue.
I had the exact same issue and it turned out to be the swirl filter. The fuel pump was out first you can check that by disconnecting the hose at the fuel injector if nothing comes out of the hose when you turn it on. Then replace the swirl filter you are most likely low on fuel pressure which is caused by the swirl filter you will have to remove the tank tray etc...

I ended up swapping ECUs and now the injector gets told to fire and the quad will run if manually fed fuel, but now the fuel pump has 0 pressure at all. I guess I will be swapping pumps out again.
