My reverse lights work until the engine reaches operating temp. As soon as the engine is warm, boom, fuse blown for reverse lights.

I have a few. Wiper speed 1 doesn't work too well. No auto return and it stops mid way through the sweep for a moment then continues on again. I also have a weird issue with the brake pedal. The ash tray light and clock back light flicker and the chime starts dinging if the car is off. Oh and the plate light flickers when I press the brake pedal as well.

The E.F.I. relay in my 1985 z31 doesn't get power. Don't know why. All of the relays "work", every thing else in the car gets power and works. This means the fuel pump gets power but doesn't run. Absolutely mint car too except this super rare and unsolved issue that makes it no more than a stationary 80's artwork installation in my driveway.

My pop up lights on my 92 240sx with pop up using the switch to turn on the lights or the pop up switch, however they will not go down when using the pop up switch, only when wind downward. Been trying to figure it out for years now, no dice.

if the fuel pump gets power, then either you have a bad ground, or a bad pump.

grab the wiring diagrams and trace where the EFI relay is fed power from, and sort out WHY it isn't getting that power.

anyone ever experience the fuel pump priming when an accessory item is switch.

This seemed to happen out of nowhere. This is when the key is at acc.

if i click on the hazards the fuel pump constantly primes

If i turn highbeams on the pump primes.

If i push the brake pedal the fuel pump primes

car is running an AEM series 2, and a walbro 255 (walbro is 3years old), Never had this issue before the car has had this set up for almost 10 years without any issues.

My CAS plug seems to be a little jack but im not sure that a bad connection there would cause this. Car also is running like shit. It definitly has fuel (it smells rich) but my afrs go lean at idle.

anyone got any ideas?

Check your grounds...

My Speedo on my S14 instantly moves to 5mph when I hook the battery up and when I turn the key on, it goes to 20mph. I haven’t even started the car yet. I just got the interior put back together and found this.

my speedometer just wont work consistently.

Before you ask:

1. yes I already re-soldered the board. It worked fine for like a week then went back to shit.
2. Yes I have tried a known working one. It worked but laggged.
3. Yes I have replaced the speed sensor.
4. yes my odometer works
