Fuel Low Light?

[GTRON]

Is there anyway to check if my "Fuel Low Light" is working?

This is kind of dumb, but I'm not sure if mine is working or not...

I would not recommend running super low on gas to check it. Gas lubricates the fuel pump. No gas = potential failure.

I know! that's why I want to know if my fuel light is going to come on!

When does yours usually come on?

Running it low once won't hurt it. You only need to do it once to learn if the light works or not. If your needle hits the E line and still no light, check for a blown bulb first.

Ahhh, running it low once could also be the failure point too. Especially on a 23 year old car which the tank, sock, etc. probably have never been changed. You can take a chance if you like. But I can see the post now... "I ran the tank down to almost empty to test my low fuel light and now............."

But I noticed this on my car too. Have a light, but never seen it come on. Even when it ran dry long long ago when I was broke and ignorant.

You should be able to simulate the low fuel light by crossing two wires off the electrical connector which is accessible from the trunk access hole like this guy did.

Check your manual for which wire does what on the connector.

That's true... though if running it low just once kills it, it was on the way out anyway!

Does the fuel lubricate the pump, or cool it? Or both?

Both. Running it low = no lubricant and you fry the pump or it sucks up dirt and it dies. Your car must have no good gas in it by now Deev, can you go test this out for us

[deevergote]

It ran on 5 year old gas!

And the fuel pump failed... so I suppose I kinda did test it already.

It's on the red empty bar now... So I'm assuming the bulb is somehow burnt out....

I'm not going to figure out what happens when I run out of Gas

[deevergote]

Good call.

Pull the cluster and check/replace the bulb. If it still won't come on, it's likely the sensor. I THINK that's what you can access from the back seat without dropping the tank... but I'm not 100% sure. Dropping the tank is no fun with 25 years of rusted bolts and straps holding it in place.

[GTRON]

how long does it take to pull out the cluster?

I'm wanting to put leds in the cluster in the future

[F22Chris]

It doesn't take long, just make sure you don't miss any screws or you'll break shit. You need a smaller flat head, and a Phillips.

If the cluster/climate control/radio cover doesn't come off easy, don't force it cause you missed a screw.

There is a drain plug in the tank; drain the tank without running the car, see if the light comes on. Capture the fuel and put it back in the tank or make sure you have some extra in a can.
