Thought I had finally got my turbo Y8 running right then this happened. Was running the engine to test the new crank position sensor, I let it get up to operating temperature and took it to 4 or 5k rpm while watching the AFR gauge very carefully, it revved up nice and smooth so I turned the car off. Went to turn the key back to ignition so I could reconnect my laptop to the ecu and noticed that my AFR gauge wasn’t on like it should have been. The check engine light was on but so dimly that I could barely see it. It cranked but wouldn’t start. SManager can’t connect to the ecu. I went to check the fuses and noticed that the 80amp and 40amp battery and ignition fuses looked a tad suspicious. The metal strips inside weren’t burnt but they seemed to lack a sort of green coating that was on the metal strips in the other fuses. I don’t know if those two fuses are just different from the others or if they are supposed to have that coating and it burned off. Would that even disrupt the circuit enough to cause a no start? I am rather concerned for my ecu as I am running those different impedance DSM injectors, but i very carefully wired the correct resistors into the injector harness and checked it with a multimeter a million times over. I’m at a complete loss here, any ideas will help.
