Gas Warning Light
 
Does the rx7 have a low fuel warning light? I see in the electrical manual that there is one, but it has never come on in my car. When should it be coming on? I have run all the way down to the E several times. I haven't gone much below the E though. I ask because I had an MR2 where the light came on BELOW the E and gave you a reserve. Is it the same way on the rx7? Or is my light just burned out? When should it come on?

There is a low fuel light. Not sure how much gas is left when it comes on.

When my fuel gauge reads 1/2 tank, it will take only about 8 gallons. At 1/4 reading it will take about 13 gallons. The fuel tank capacity is just over 20 gallons. This leaves about 7 gallons in the tank with 1/4 reading. Its not surprising that the low fuel light doesn't come on when the needle hits "E".

Ah, that would explain it. I've never put over about 18.4 gallons in the tank. I bet I've just never gotten to the low fuel light.

Does it go on when you turn the key, or does it only illuminate when you actually have low fuel?

bajaman 11-05-12 05:51 PM

This lamp, like all the warning lamps, will illuminate when the key is turned to 'on'. If it isn't coming on, it is burned out.

To OP...I wondered the same thing for the first year I owned my car...then one day it got low...as in I thought I'd be pushing it low...due to my own forgetfulness. The gas light came on at that time...I was well under E.

1 1/2 to 2 gallons it will light!

FC578332 11-05-12 07:39 PM

usually the fuel light will stop working then the float in the tank will stick, mine dosnt work either

SA3R 11-05-12 08:57 PM

Where is the light located on the dash?
I turn my key 'on' and all the dash lights illuminate, but I dont see a low fuel level light anywhere?
Maybe the JDMs dont have it, whereas the USDM does..?

It's a small dot on the fuel gauge. The JDM clusters have them as well, it's VERY hard to see when not lit. The warning light for the coolant/oil gauges are the same design.

Thanks Dale, I checked mine, and there's no dot in the fuel gauge?

I'm assuming you mean the same design of dot as in the oil press/coolant gauges- small 1/4" red light that comes on, otherwise just a very feint black circle when not lit. I can see the lights feint outline for oil press & coolant when they arent lit, but my fuel gauge definitely does not have one?

It is between the E and the fuel pump symbol. It is a little harder to see if I remeber right it will light up orange.

my fuel light comes on just before the needle is even near to touching the bar of E

I have a 92 JDM FD and it has the low fuel light... never had it come on from lack of gas though. It does light up when the key is in though.

To be clear, do people support bajaman that the light should come on whenever I turn the key to on regardless of fuel level?

No. Low oil press and the coolant light will light up red when key is turned on. The Fuel light is an orange light and in my car it doesn't light till you are dead equal will the E line. As some one else mentioned you only have like a 1 1/2 gallons at this point.

Don't boost under 5/16 of a tank unless you have baffles in your tank.

You may have more than 1 1/2 gallon when I was getting my car ready to drive after sitting for a couple of years I decided to replace the gas first. The E light was on so I didn't think there was a lot of gas in there, man I was wrong I ended up filling a 5 gallon bucket.

RotaryEvolution 11-06-12 02:46 PM

the fuel light is the only one that does not illuminate when priming the car, iirc.

it only turns on when on reserve.

I was going off the idea thinking that its about a 20 gallon tank, when filling the car with the fuel light on its around 18.5gallons. Things that make you go Hmmm

Anyone ever run their FD out of gas??

RotaryEvolution 11-06-12 04:16 PM

older FDs, over time the sending unit gets worn and becomes less accurate towards the lower end of the spectrum. the majority of it's lifespan the sending unit is constantly sweeping over the lower half of the unit.

phdofski 11-06-12 05:16 PM

The warning light is the only thing on my fuel guage that does work and it will catch your eye when it comes on. Good thing for tripmeters.

bajaman 11-06-12 07:17 PM

In section 4-23 of my owner's manual it specifically states that ALL warning lights will illuminate when the key is turned on, and then addresses what to do if any one of them comes on whilst driving.

Look it up. :nod:

Here is a pick of my car with the key on, engine not running. Notice the low fuel light is not on and the oil and coolant are. My low fuel light works.

bajaman 11-06-12 08:09 PM

^ Hmmmm...can't argue with that, I guess. :scratch:

But then again, my owner's manual says I have an "static discharge panel" inside the door handle that I've NEVER found....lol!

seandizzie 11-06-12 09:56 PM

Static discharge panel... that reminds me of the time a buddy of mine ran a wire off an ignition coil discharge to the seat of another friends car, so when he started the car it zapped his ass... lol!!!

I actually know the answer to this one! :) Because I've repaired the static discharge touch panel in my drivers door. When you put your hand inside the door-pull pocket to open/close the door, the rounded soft textured area your fingers touch on the inside wall of the door-pull pocket has a very thin (like paper) sheet of copper attached to the back of it, which runs along the door trim and grounds out to the steel of the door, behind the door trim. Should have taken photos of it last time I had the trims off... It isnt voodoo. The static panel really is in there. Logic is that when you open the door to get in/out of the car, your hand goes into the door pull handle, touching the static panel, which grounds you to the body of the car, and prevents you getting zapped by static upon exiting and entering the car. I know it works, because I removed the static panel on the passengers door, and now my girlfriend gets zapped every time she exits the car.. :icon_tup:

Anyways, back on topic... Could someone post a pic of the low fuel light lit up, for everyone's reference?
