Hello all

Last night I'm cruising down the road at a nice 40mph stretch of road. Since no one is around (and it's rather late) I step on it a bit and let the motor breath. Long and behold I hit a pothole at about 50. Wasn't a deep one, just a nice "bump" in the road. Well sure enough the fuel light comes one, nice bright RED light at night was just lovely. Fuel gauge says half full but for insurance I stop and fill up. 8.45 gallons go in (roughly half a tank). Turn the car back on light is still on. So question of the day, how exactly does the light work, is it a grounding circuit like on old fords or is it a wire lead with voltage like a few others? I haven't been under the car as I didn't get home till late and haven't had time today (was doing brakes on a 620).

Any suggestions welcome

Check around the fuel pump sender. According to the wiring diagram, there are two wires. One is green (power from the dash lights circuit), and the other is yellow/blue. The Y/L wire goes back to the sender.

I have three wires, one is blue/yellow, one is blackish and the other is yellow. They all go to a connector which is covered in a nice heavy amount of dirt.

Sorry, I was tired when I typed that last night.

Green and yellow/blue are from the light.

As I said yesterday the Y/L wire goes back to the sender. That is the negative side of the circuit. I haven't ever seen a 280Z sender to know how it is wired. However, I would guess that your problem is either that or a loose piece of metal is grounding out the negative contact on the light.
