z32 help: Nothing works when ignition switch is turned to "ON/ACC" - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

My 1990 300zx Twin Turbo is having issues with the ignition switch. When I turn my key to "on/acc" no dash lights turn on and of course my car will not start, it doesnt make a noise when I turn the key. My headlights/dome lights/alarm still work and it still makes the chime sound when my door is open. I initially thought it was the security system, but after tracing everything down I'm suspecting it's an ECU issue or a blown fuse somewhere. Is there a fuse for the ECU somewhere that I'm not aware of? Maybe a broken ignition switch?

This all happened after I had my car valeted last night. I turned off my turbo timer so I wouldn't confuse the valet, and when I went to pick up my car after dinner the valet came back and told me "your car isnt starting". I have a feeling it has something to do with the turbo timer that blew something. I uninstalled the turbo timer and still nothing works.

My car is all stock 1990 TT manual and is all stock except an HKS type 0 turbo timer.

Any help would be appreciated! Thanks!

Check the Clutch "Jelly Bean".
When you push down on the pedal it hits a switch to start the car.
You can hold it with your finger and turn the key

Gave that a try, but unfortunately it wasn't the case. None of my dash lights are coming on and my radio, windows, etc arent getting any power and I assume my starter/coils aren't getting any power either.

check alt fuse under hood or wires under ignition
