Is there a way to test the Red low fuel warning lamp on a Sapphire Cosworth?

I know it comes on when the ignition is turned on and the Amber screen wash flashes a few times but thats it.

I have ran it as low as I dare before it runs out but I'm wondering if it will ever come on.

Any ideas peeps

Screen wash shouldn't flash - if it does it means the sensor is faulty.

Well run it lower matey lol its nearly on bottom of the red before it comes on.

The low fuel comes on then goes off.

The screen wash flashes 5 times then goes off. I'm sure it states that in the manual....

Mine came on for the first time the other day, it came on when i was at the bottom of the red, drove to the petrol station about 5 miles away and it didnt run out.. im sure i read in the manual it has 10 litres left in the tank i wouldnt really want to try it though.
My screen wash light comes on when i flick the ignition.. but doesnt falsh. Does the same in my dads car aswell, but thats an xr so could be different.

Na probably just dirty lol

as said above if the warning lamp flashers there is a problem with the sensor.

my petrol warning lamp come on when the gauge is reading below the red and on a long run i have done over 40miles with the light on, but round town i don't leave it much longer then 20miles befor i fill up again

Do you mean the amber screen wash light bud? mines flashed since day one and after 5 flashes it goes out. When the washer light level gets low it does come on though.

I'll have to leave my petrol to go right down next time and see what happens....

nicksaph

yes mate the ones above the clock. had five sierras over the years mate and non have ever flashed unless there was a problem with the sensor or wiring

Odd.....

It does work though.

Ignition on and the fuel light comes on steady and the screen wash flashes 5 times then all lights go out.

When screen wash is low it comes on.

I am yet to see the fuel light come on.

Yes as said if either bulb flashes when switched on it indicates a fault, think my light comes on near enough on red. If your comes on when ignition comes on and then extinguishes this indicates bulb and circuit good so maybe sender is not making contact.

The fuel warning light comes on at the top of red in my cossie, on my other normal sierra it dont come on until the very bottom of red and when it does the fuel computer says ive got 50miles left.

in my 1992 the fuel light comes on just under the red and will do about 30 miles atleast with it on, the screen wash lamp doesn't flash.

A flash on any of these lights is a sign of a dicky connection, on that circuit, I am sure I read somewhere it being 1.8 gallons when red comes on, but best not chance it!!

How does my screen wash light still come on when its low if it flashes on ignition?

I thought it was just checking itself out?

tabetha

The check procedure is they come on for about 5 secs then go off if all is well, there is likely a high resistance somewhere on the line.
