Question about 2000 Mercury Cougar

1 Answer

2000 Cougar, 2.5 V6, Automatic. So heres the deal, the fuel gauge doesn't work so I have never tested one before. I mean its not like they go out alot or do they in cougars? Did Some research and the sending unit is allin one with fuel pump and dealer wants $500 for one? is it made of gold? Any suggestions, I even researched if they had 2 different fuses, no such luck. Thx for your time and effort in this.

    So ASEcertified, your answer is to put gas in it? I thought this was a serious website for answers. If my only choice is to replace the sending Unit/ Fuel pump then say so.

You would check the white red wire going into the tank for reference voltage from the gauge, then see if the sending unit in the tank is grounding the circuit. You should be able to ground the wire going to the gauge and make it move.

96 Mercury cougar gas gauge won't work

Cathy, 1996 Mercury cougar gas gauge not working. Simplest thing to check first is your fuel gage fuse, make sure all fuses are good. The ground wire could be corroded/damaged, sending unit in tank faulty, fuel level gauge in cluster faulty. All things can be tested by a good Tech.,diagnosed and estimate for repair.

2000 tundra v6 dtc p0172

172, are USA standard, spec, DTC error.
and as such , all posts covering it should be same.
P0 means fed, rules.
this only means, this sensor reads too rich.
mostly it is 2 things, #2 is vast things.
1: the sensor is bad. B1S1. (bank1sensor 1) sensor 1 is front.
2: Air fuel ratio , fueling is very very rich,

a technician does more tests to find the true cause.
You could replace and over 100k mile sensor, and find it still throws
that means the EFI is out of control, its rich for many reasons
1: too high fuel pressure? use a gauge.
2: leaking injectors. (same gauge above doing the leak down test stated in the FSM. and not skipping the injector balance tests.)
3: Misfire , for any reasons, (vast) that cause EFI to go rich.

hard to beat this list, but there are many tests to do
even coolant temps, wrong.

Fuel gauge not working properly. Says fuel tank full when fuel tank empty

Could be 3 thing - the gauge on the dash, the wiring or the fuel level indicator in the tank. All three are not easily accessible - the best test would be to measure the voltage on the level sensor on the tank.

It usually means removing the fuel tank and start measuring. If its ok, supply voltage to the lead towards the fuel gauge. If the gauge doesn't move it's wiring or the fuel gauge itself.

I have a 200 mercury cougar 2.5 v6 and i have a problem with the computer system. it runs and idles fine but the electronics in the gauge cluster resets itself once an a while, and sit just the gauge...

For this problem straight solution is to use a diagnostic scan tool and retrieve fault codes which will tell you the exact problem. Could be bad earth or short somewhere or loose connection.

I have a 2001 mercury cougar with the 2.5L v6 engine and the number 2 cylinder is misfiring. ive replace the spark plugs and wires but it still misfires

Its time to do a injector balance and cylinder leakage test, to determine whether the injector or its circuitry is bad . The leakage test will tell you if the cylinder has a compression leak.

(3.2 v6)odometer not working, gas gauge also acting funny. the rpm feels like we are in 2 or 3 gear when we are not.

dear friend-it sounds like your vehicle went into limp mode,you can disconnect the battery in order for the ECU to reset,then if the vehicle feels ok then take it for a diagnostic test
