Had a no start with my 04 xb12s this weekend. First off always check the simple stuff first, lol. I had a bad ECM relay and a loose connection in the fuse block. When I would turn the key on it would only turn the gauges on and give me a neutral light and oil light. No check engine light for a few seconds and no fuel pump prime. ECM wasn't getting power. So if someone has this problem is a good place to start. I searched some with no luck.
Now I'm stubborn and swore it was a broken wire or something so I spent three hours ohming wires and dissassembling and cleaning the ignition switch and kill switch and trying to find any shorts. Don't be like me. Just follow the flow chart in the service manual if you have one. First thing was to check the ECM relay as soon as I moved it with the key on the fuel pump kicked on.
