can you use pin-nose pliers to grasp the key or a Popsicle stick with an adhesive to stick to the broken key and remove that way

it resets itself.

Principles of Operation
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code out of over 18 billion, billion combinations.
The passive anti-theft system (PATS), also known as SecuriLock ®, uses radio frequency identification technology to deter a drive-away theft. This system is known as SecuriLock® in North America, Safeguard® in the U.K., and PATS in Continental Europe. Passive means that it does not require any activity from the user.
The SecuriLock® System (PATS) is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. If equipped the remote start system must be removed before investigation of PATS-related, no-start issues.
Each encoded ignition key must be programmed into the vehicle's powertrain control (PCM) before it can be used to start the engine. There are special diagnostic repair procedures described in this section that must be carried out if a new encoded ignition key is necessary.
This system contains a new feature named Unlimited Key Mode. This feature allows a customer to program more than eight keys to the vehicle if they request it. Each vehicle in Unlimited Key Mode is set up with a special Unlimited Transponder Security Key. This allows all the customer vehicles to share the same keys, but no other keys from outside can be used to operate the vehicles. For an individual customer, any randomly selected Security Key is acceptable. Refer to Unlimited Key Mode Programming in Key Programming Switch State Control in this section.
The PATS transceiver module communicates with the encoded ignition key. The module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends data to the PCM.
The control functions are contained in the PCM. This module carries out all of the PATS functions, such as receiving the identification code from the encoded ignition key and controlling the engine enable. The PCM initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
All elements of the PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
The PATS uses a visual theft indicator. The indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS concern, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. The PATS system also flashes the theft indicator every two seconds at ignition OFF to act as a visual deterrent.
The PATS will be activated and will disable the vehicle from starting if there is a:
  • incorrectly encoded ignition key
  • damaged encoded ignition key
  • unprogrammed key
  • non-encoded key (key has no electronics)
  • damaged wiring
  • damaged transceiver
  • damaged PCM

Check to make sure that the snorkel is not restricted. I have seen rubber hoses that have gone soft cause a whining noise. Check them especially the pcv hose.

The Cougar uses the same platform as the Contour so it should be like it is on my Contour. Remove the rear seat bottom and you'll see a cover in the floor. Remove that cover and you'll be able to see the top of the fuel tank. You'll need to remove the lines coming out of the top and use a punch with a hammer to rotate that locking ring. Once you remove the ring you can pull the pump module out of the tank. Be careful not to bend the fuel level float. You'll be able to see how to get to the pump once the module is out. Just take the cover off and put the new pump in the module and re-install.

Most likely you have a broken belt. As a result the AC compressor is not turning and more importantly, neither is the water pump. Replacing the belt is easy but why it broke is another question. Might have just worn out but If I was a betting man, I'd bet the water pump is seized and will have to be replaced. Don't drive the car more than a couple of minutes before having this checked out.
