So I just installed a wiring specialties harness on my RHD z32 NA, but after installing everything it won’t start, the engine will crank, but it will not run, me and my friends have tried changing the chassis ground and intake grounds but to no avail, all the wiring is in properly and everything is lighting up on the dash like it should, I even checked the PCM for any codes flashing on the potentiometer, but it gave me the 5-5 all good code, could there be something that I’m missing?
