:P ive owned my r33 for over how many years now, and to this date i thought it never had a low fuel warning light. now yeterday as i was reversing into my driveway it came on for the first time ever ever , and lasted for about 20 secs untill i reversed up. it then slowly dissapeared. any clue as to maybe where the problem might be ?

how does your fuel senors work is it from the tank that might not be working well and cant send the message most of the time to light up or dash problems ?

not sure how it works in a skyline, but in my tx5, if the tank is low on fuel, and u turn a corner etc, that can make the light come on if the fuel goes to 1 side and the sensor thinks there's none left...

then as it evens out again, the light slowly fades

ive owned the car for a few years and ive on some careless occassion being many run the fuel very very low and its never lite up to give me warning before untill it did now for its first time in history.

i want it to work, like normal, so what happens if it was a one off thing and it doesn t choose to work again?

what do i need to look at to get it working constantly?

as far as i'm aware, the light basically works with the red line on the fuel gauge...

when i turn the corners etc, and the fuel moves around, the gauge changes, and if the needle gets into the red the light starts to come on...its not straight on straight off, it fades in and out depending how far the needle falls into the red

yes. but if you're not hard under boost or anything, it's not really going to cause damage. a risk you may run tho is sucking any shit in the bottom of the tank into the fuel lines, and clogging the fuel filter. rare, but possible. I'm guessing you weren't running the tank as empty as you thought you were...

I've actually read that in the fuel tank there is a little sensor knob thingy.. and when it drops past a certain point the fuel light comes on.

Bear in mind, if u are on any sort of incline the fuel in the tank is obivously in a different state as well because of our friend mr gravity.

So what you'll notice is that if you are facing downhill, it may seem like u have MORE fuel in the tank (negligible) and if u are facing uphill, the car will think u have LESS fuel in the tank because the all the fuel has shifted to the one end of the fuel tank, and the sensor has passed it's 'low fuel' point meaning ur light comes on.

Hope this helps dude.

yeah dont worry about it, u wil still have like a good 50-60kms of driving to go, on a cold nite if it comes on and i cant be stuffed, i just leave it to the morning, no harm done, ive let it go really low, i think i pumped in about 58 litres, cant damn remember, but the light was still fading on and off. i found sitting at lites on idle, it will slowly come on, and when i take off steadily it will fade away. Weird.

      R34 25GT Engine Light 21

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!

      You think its the AFM? I know its a common issues on R32s. I find it coincidental how this issue raised right after cleaning the fuel system. As everything except the fuel system was fine before. I tried running it with the IACV unplugged but did not notice a difference and still stalled. However, the RPM gauge is not in the cluster right now, so I will need to connect the laptop again and use Nistune to check the RPM. I will check this weekend.
