Question about 1999 Mercury Cougar

1 Answer

I have a 2000 cougar that wont start when it sits for more than one hour,

The antitheft comes on then goes out right away,if we cycle the key enough the car will start.When the car starts it will start every time after that if you let it sit for one hour the car will not start again.We have changed the pcm,the TR sensor and the sensor on the steering column and it stll did not fix our problem

Hmmmmmm....this one might have to go to FORD to be fixed.Have you replaced the fuel filter?
That's probably not what's wrong, but if it's been a while,it won't hurt to change the fuel filter anyway.
Keep any source of spark away(trouble light,electric cord,etc.)when you take the hose off.Of course relieve the pressure at the fuel rail relief valve before attempting.

SOURCE: Car is hesitating at time as if timing was out of whack

try cleaning out the idle control Valve. also called an IAC. Using brake cleaner remove the duct from the air cleaner and spray directly at the valve. It sits near the opening . It is a small component with 2 small hoses. If you can, remove it and spray right into the 2 holes on the underside.If that is not the problem it could be the EGR valve.Sludge bulidup in the IAC is a common problem.

SOURCE: 94 mercury cougar wont run after 10 min

the fuel filter is either blocked or installed in the wrong direction.the rotor and distributor cap are fine. swop the fuel filter around and try again.

what is anti-theft light doing? It should come on solid for about 2 sec after you turn the key on then turn off. If it is flashing after this then it is not seeing the computer chip in the key and you have a PATS problem.

check your fuel pressure to make sure it is coming up to spec. if not, then replace the fuel pressure regulator. there are some sensors that come into play during the starting cycle and warm-up cycle that do not get read by the computer at operating temperature. you will have to see which ones in your vehicle monitor during the ignition phase to see if any of these are failing.

Can it be the antitheft system that makes trouble and wont let the engine start?I had a similar problem on my KIA Sportage 2002 and had to replace antitheft system and the main computer.It could also be the starter relay. Have a friend to turn the ignition key, and tap the starter relay (the one on the starter) as it may be stuck. Worth a try, as it would be the cheapest solution to the problem :-)

Lookfor a light on the dash that says SECURITY or ANTITHEFT. If you see this light, that is a sign of a failed or failing antitheft system, which will disable your vehicle. This link explains
