1996 R33 GTS-t, big fuel pump fitted in tank. Has been OK for 2 years, but today, on a track day, the engine just stopped. No power to pump. Hot wired 12 volts direct to the pump and got home OK. I believe there is a dual voltage set up on these, and they idle on low volts to the pump, and get 12 volts under load? Where is the control stuff for this situated, is it a relay or a solid state device, and are they troublesome running a pump with a bit more current draw than a stock one? Many thanks for any replies, cheers.
