I have a 1993 RX7 FD3S Base that having issue. Yes i search in the forum seem like most of them does not seem to have hazard/horn on like the vehicle im looking at. Vehicle does not start, no crank, no click, Hazard/horn are on, Dash is lit up with all the lights.

Battery is fully charge
Try jumping starter relay/clutch switch does nothing.
Visual check on the fuse at the engine bay. I will check ohm them to double check
Try to see if there is fault code with the paper clip at the diag port does not show any fault

I will be taking the starter out soon to bench test it to confirm the operation of it.

Sounds to be it is an immobilizer/alarm issue. Does anyone know how i can check/test this??

Thanks

When you put they key on 2 does everything come on like normal? Fuel pump, radio, windows work, headlights.... all that?

Flashing lights and horn are the security system going off. You can probably just unplug CPU #2 for troubleshooting purposes, that has the whole alarm system in it. Then figure out why it keeps tripping the alarm.

Also I would hook up the battery with the doors all unlocked. If it tries to flash/honk, put the key in door lock and lock/unlock the doors. If it's still doing it turn the ignition to On. If still doing it, go the CPU#2 route and troubleshoot more later.
