Hi, I've got an 02 RX DI that doesn't want to start. The fuel pump and external fuel filter are new. Although I have not yet checked fuel pressure or air pressure, I found this interesting behavior. When I hookup CanDoo, it has codes P0105 and P0106. I exchanged the MAP sensor with a sensor from my other DI ski which runs fine, and the result is the same. If I use CanDoo and choose DI Activate to turn on either the MAG or PTO fuel injector before I start the engine, it'll fire up and run just fine without any problems every time. But as soon as I stop the engine and try to restart, it won't fire up. It only fires up after activating a fuel injector. Before I spend money on fuel pressure or air pressure test rigs, I thought I'd find out if anyone here has some tips. Perhaps take apart and check the fuel rail? It's just weird behavior that activating either fuel injector before starting will 100% fire up. Not sure why that would work.
