Alright guys I need the LTR veterans and gurus serious help. I’ve been chasing an issue for 3 months now where my injector will not spray fuel. I’ve changed ECUs, whole wiring harnesses, tip over sensor, calibrated TPS, and tried 3 different injectors. It’s also not throwing any codes to read to even point me in the right direction. I’m about ready to give up on it. 😩🆘

There's a guy on YouTube who hooked his up to a battery and there's a motor for that injector I'll see if I can find the link if not just search on YouTube maybe fuel injection problems

The quad actually runs now. It ended up being 2 bad ECUs in a row but the 3rd one was the charm. I've been riding it for a couple months now but now i am thinking it needs new valves as the intake ones are out of spec and can't be shimmed any further :(
