I recently bought a 2001 Sea Doo Challenger 2000 with a Mercury m2 efi v6 Jetdrive engine. The fuel injectors are not firing. The fuel pump has a lot of pressure and all the injectors work but something is stopping the fuel injectors from firing. Should I be looking at any of the sensors? The engine is getting spark in all cylinders. The vst fuel pump wiring stopped working. There was no signal to the fuel pump when I would crank the engine. I checked all the fuses and they were all good. There are 3 small fuses attached to the engine and I have only found schematics that show 2 fuses. I am wondering if some of my wiring or sensors are bad. Any tips anyone?
