There are a few different thing s that could be wrong. From easiest to hardest: 1. Loose or corroded battery terminals 2. Loose or bad connection with wires to either starter or solenoid 3. Bad solenoid 4. Bad starter It's hard to tell what's wrong without knowing sounds and other such things.
Have the alternator checked.
start your car and then disconnect the battery if it dies then it is your alternator that is what i am working on right now but good luck if it is the alt you have to drop the motor cradle
how can you start a '89 mercury cougar with a broken ignition switch?
If it runs for a little while then dies it could be your alternator.. If it ticks or just does nothing its either your battery or starter.
Needs a new starter
take the terminals off the battery and run a wire brush through them, or sandpaper.
1988 cougar will not crank over
Where is the EEC connections for a code reader on a 1995 Mercury Cougar? Is there any suggestions why the engine won't turn over. Only a ticking sound is heard and sparks from the battery sometimes appears when trying to start.
Typically it means you should start saving for a new alternator. One of the not so rare engineering flaws on this generation Cougar is the alternator, which will die due to poor factory wiring fairly often. There are mods to fix this problem, and Ford Lincoln Mercury dealers will see instructions to change the wiring of the alternator to be like that of the '01 and '02 Cougar2s when they go to change the Alt, not all alternator shops will necessarily know this is an issue. If you take this on yourself, know this, the after market (ie motocraft) alternators for the Cougar are not nearly as reliable as the genuine Ford OEM product. And also, even if you take the alternator to have it checked at pep-boys or such, it will probably show that it is still good while it is indeed the issue.
Might be you alternator. Happened on my 1997 grand marq a couple of weeks ago
As long as the battery is fully charged it will start no matter the condition of the alternator. Eventually the battery will run down if the alternator is not keeping it charged.
A clicking sound when you try to start the car is a dead battery. It may be that the alternator is not charging it properly.
