Question about 2000 Mercury Cougar

2000 mercury cougar won't start

This problem seems to happen when the outside air temperature start to get cold, below 30 deg F. The check coolant light comes on. I have checked the coolant and it's OK. So thinking that this is a fluke I turn the engine off and try to restart it but it won't start. My wife said if she lets it sit for 5 minutes or so it will start up. I tried that but no luck. The car cranks well but just won't start. I thought that maybe the anti- theft device was malfunctioning, so I lock the car with the remote and opened it but nothing changed.

    the solution given is does not address the problem. I have lived with all those problems for 60 yrs. I don't need, I'm sorry if I offend someone, stupid answers. I need a brain. I can fix anything some times I just need to know where to look or what to look for.

Clinholm,

You said you checked the coolant. By that did you mean you checked that there was coolant and the level was full? Or do you have a tester that can tell you your Antifreeze ratio.

What I mean by Antifreeze ratio is, that it is recommended that you have a mix of 50% Antifreeze(coolant) and 50% water in the cooling system. If theres too much water ice can form in the system blocking your hoses. You can get a tester for your coolant at Any auto parts store for about $10

While ice in the hoses may cause the symptoms you're seeing, What I believe your actual problem to be is an old or undercharged battery. What Most vehicles have for a battery is called a "Lead acid" cell. This is basically a plastic case that has a series of lead plates dividing it up and hydrochloric acid. the acid chemically reacts with the lead producing electricity and water. Well over time the level of Acid to water eventually becomes more water and so when it gets cold outside and that water freezes, it causes the battery to NOT be able to produce enough charge to start your car.

If this turnes out to be the case a short term fix is before your start the car turn on your healights for 30 seconds to a minute. This will get the current flowing, warming the battery a bit. Then you can start your car.

But if you do have an old(2 years or more) or undercharged battery. I'd get it replaced.

Best regards
Dave

Put the electric heater or any thing which produce some temprature, exactly below the engine, on floor for ten minutes before start. 
it works
or replace  the battery of car so the ignition lasts for a while.

Try unpluging the Ignition control module while the key is in the on position. Wait until you here the relays click, then plug it back in, next do not shut the hood or door, try starting it. If it starts, then you either have a bad Ignition module, bad harness connector or a sticking relay. This is the problem I have on my 94, but it happens more when it is hot. I discvered this while searching the internet for my prolem. I saw this for both hot and cold conditions. It is call the famous Ford connector wiggle test.

    The very basics of starting are you need spark, compression and fuel. Missing one of those causes the car not to start. My guess is your car is losing its fuel charge when the engine is very cold, combine this with a weak ignition coil and this could be the problem .....

    You could have a bad keyswitch on your steering column. Could be other things as well. What you'll need to do to diagnose this problem (to be sure), is to get a voltmeter and a set of electrical schematics for your vehicle, and then when you are having the failed condition start monitoring voltages in the start circuitry.

    Oops ................i m srry didnt read all ur comments :P

    .





    Uhmm.......I am sorry to say but it has nothing to do with ur ignition module as i said above.





    The reason behind this is a logical one :-





    Whenever u turn ur key, there is always a spark which have sufficient energy to keep ur car warm....No starting issues...However, in winter u might have to turn ur key again and again as the car wld only start when its enegrgy requirement wld be met.





    U might have seen ppl living in cold temperatures , used to put antifreeze liquid in order to keep their car warm from inside.



    Mercury 2000 engine works the same way in winter.



    "A cooling system is used to evacuate the heat from the engine. Without cooling, the engine will overheat and get destroyed within the hour. Therefore combustion engines have a cooling system. The most common
    is a liquid cooling system. The best cooling liquid is water. To prevent freezing, antifreeze cooling liquids can be mixed with the water. Apart from the antifreeze properties, these products also contain components against rust, corrosion and scale"...................



    There are many anti freezing liquids available in the market like wynn's supreme.......





    Take care bro.

    HELP AT DIFFICULT STARTING

    Winter times with low temperatures and high humidity make especially older cars suffer from severe starting problems.

    A combination of these problems leads to a very difficult cold start of the engine. Starting help is needed and can be given by injecting a very flammable product with easy ignition properties into the air intake manifold.

    Wynn's Starting Fluid
    Is a petroleum ether based product which very easily evaporates, even at very low temperatures. When sprayed into the combustion chamber during starting, the ignition will easily be initiated. The engine starts on the product. Once the engine starts running, the fuel system can continue the combustion. Even at very negative temperatures the engine can be started.

Hi,

id say you have a problem with the fuel injection system or a bad electronic sensor, the injectors may be clogged, or wore out or may have a leak.

the problem could be a bad electronic sensor. These devices
monitor certain key engine factors as well as outside air
temperature. If one of them fails, it could throw the entire
fuel system off and thus cause starting problems.

hope this helps.Please dont rate me if not satisfied.

Thank you

Starting your car in cold can be a big problem. There are three main reasons why the beast won't "purr".


1. Gasoline must be vaporized to burn and it evaporates slowly in the cold. (Sometimes people spray ether into their engines to get them started - ether evaporates faster than gasoline in cold weather.)


2. Cold oil gets stiff - making it harder for engine parts to move (a block heatercan warm up the engine block), and


3. Chemical reactions in cold batteries are slower so the battery produces fewer electrons - making it too weak for the starter motor.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

Engine temp low when it's below 30 deg. outside. coolant feels cold in bottle just after driving, even on highway when it's could outside.


From the sound of it, the thermostat is stuck open not allowing the water to stay in the engine and get hot.I would check that first.

Check the antifreeze level. It could be low, When the air turns cold all of the sudden there is an air pocket in the cooling system. Watch for coolant leaks and if it continues to get hot replace the thermostat.

When the motor is cold and the outside temperature is below 70 the car will not stay running. Will die with in 30 seconds or so of starting, then you have to wait a minute or two befor the car will start...


Are there any service engine soon lights on associated with this problem?

Possible CTS (Coolant Temperature Sensor) or another sensor giving faulty data for the cool air temperature.

Check spark and gas delivery when cool, below 70 deg. If the spark is not being delivered or the fuel injectors are not delivering fuel at this temperature, it will explain why it doesn't run right until it is warmed up.

I would check for a bad coolant temperature sensor, of a bad ambient air temp. sensor. You can check these with a good voltmeter, but a scanner would make things much easier. With the scanner, you can se what the computer thinks these sensors are telling it. If it's 20 outside and one of the sensors reads something like -10, there's the problem, but a five degree variation is not enough to make a difference.

Low Heat on 1999 Mercury Cougar


I had the same problem with my 199 cougar 2.0 4 cyl.
The problem was air in the cooling system.

I had to bleed the air out of the system, and now the heat
works much better.

I put a flushing tee between the back of the thermostat and
the heater core, and made sure that water flowed out of there.
Then I disconnected the small hose from the top of the coolant
resevoir, and poured water into it using a funnel until the coolant
level started to rise in the coolant resevoir. Then started the car, left the radiator cap off, and let it come up to temperature (thermostat open)
then over a period of about 5 minutes, periodically "goosed" the engine to clear any remaining air bubbles.

The heat is MUCH better now.
