In most cases the sending unit inside the fuel tank is faulty.
my light went off when i put a new gas cap on and unhooked the battery 10 min too reset
First, if your Mercury vapor lights are cycling on and off you probably have a bad ballast. Any ballasted bulb will be much less efficient when cycling on and off. The greatest amount of power is used when the power is first transmitted through the gas within the bulb. Second, Florescent bulbs are just about as efficient as mercury vapor lumen for lumen. Hope this helps Terry
Connect a fuel pressure gauge to the injector fuel rail. Watch the fuel pressure when you start it. If the pressure drops off as the engine starts running bad, it's probably either the fuel pump or fuel filter.
Doesn't have one, that is a Ford/Mercury thing.
The temp sending unit on the engine could be unplugged or faulty.
Not unless you have run out of gas.
If it takes 30.00 to top off the gas tank, but the gas gauge shows full on an 85 F150 4.9 Straight 6, it is likely that the gauge is not reading correctly. Replacing the gauge cable can remedy this.
It is quite possible in a 1996 Mercury Cougar, that when the dashboard instruments all quit at once, there is a fuse that has been blown. Most of the gauges in the dash run off the same fuse in most vehicles.
ummm,try unscrewing it?
It should do just the opposite. I would check that gauge.
the pcv is at the back off the engine under the upper intake in the lower intake
Mercury is made of mercury.

First take the mercury oxide and heat it so that it decomposes completely. This will drive off the oxygen gas and leave you with elemental mercury. Record the exact mass of the mercury that you have left at the end of the reaction. Divide this mass of mercury by the original mass of your mercury oxide sample and multiply by 100. This will be the percent mercury by mass in your original sample.
The gauge check light is just a reminder to check your gauges.Probably your fuel gauge is below a set point.Just put gas in it and it will go off. Rember..its not the check engine light...
Why does my 2000 dodge neon shut off when my gas gauge hits a half tank of gas then u recycle the key to start it again and it starts up
Is there a gauge panel dimmer wheel switch ? Try rotating it , it may be rotated all the way in one direction
