Tore apart an 07 Raptor 700 that hasn't been started in a few years. Quad was tore down and rebuilt, went through the wiring and cleaned and greased all the connectors and when it was time to start it wouldn't. Current situation key on, engine switch on I get a neutral light but no other lights and no fuel pump turning on. It will crank but does not get any spark or fuel. Relays for clutch, neutral, fan and light relays work. The fuel pump relay works if I ground the wire at the ECU. I've taken the lean angle sensor apart and made sure it's clean and moving, replaced the fuel pump relay assembly. Thought it must be a bad ECU as it's getting power and ground but not sending any CEL, replacement ECU did not change the symptoms. I've tested several wires at the ECU to test power grounds to different components and can easily kick on the fan, reverse light, check engine light (thought maybe the bulb was bad), fuel pump. At this point I'm at a loss what the issue could be to not at least get a CEL.
