Need some help. 2000 HPDI 200Z starting loosing spark. I have done the following. check stator, pulsar coil, switched ECU and injector driver to running engine, they ran fine. Isolated the boat harness with a remote start assembly, checked the relays and fuse holder, all OK. I even cut the white kill wire to the ECU just to make sure it was being grounded. The ignition coils are all getting 12 volts from the battery. I have checked continuity to the harness where I could get to. Neutral switch is good. Can I have a bad harness? NO codes on the ECU. I am the 4th mechanic on this motor!! Could one of the sensors short to ground and cut all spark?, I would not think so. Any help would be greatly appreciated. Thanks.
