Hey, so I bought a 2006 LTR450 and it cranks but won’t start. I put a new battery on it and new stator/crank position sensor. I’m getting no spark and when I turn the ignition on the fuel pump relay will sometimes buzz meanwhile the fuel pump will run like it is supposed to. The injector isn’t firing when cranking but I have hooked it up to a 9v battery and it does work. So basically it comes down to the ecu not sending a positive signal to the ignition coil to fire and no negative pulse to the injector to fire. The ecu is a programmable procom ecu running stock map right now. I’ve tried checking codes threw the fi light and can’t get anything and now I’m stumped

Find a friend or someone that is willing to swap the ECU with a known good stock one. If it still doesn't work it's probably not your ECU. IF it does then bam. Test accordingly.
