Hi i have a 2000 model s2000 and it has a history of issues with the immobilizer.. My history with s2ks tells me the green light blinks on key insert.. Mine doesn't even do that at all. Fuel pump is jumped at relay to run. Ecu is known to drop key program history every few months.. I've been working on this car for about 2 months now from rolling chassis. Having a few bugs to sort through but this should be to cover the Immobilizer issue. Practically the question is what feeds the green light power etc.. Drawing kinda blank on diagrams
