A 1999 Mercury Cougar Won't Crank
- 1). Try to jump start the Cougar's battery using jumper cables and another vehicle with a battery of comparable voltage.
- 2). Run the engine at an idle for several minutes if the jump is successful.
- 3). Turn off the Cougar's engine and disconnect the jumper cables.
- 4). Try starting the Cougar again. If it doesn't start at this point, the battery isn't holding a charge or the alternator isn't charging the battery. Auto parts retailers such as Auto Zone and Advance Auto Parts provide free testing services to determine which of these components is malfunctioning.
- 5). Consult a qualified automotive professional if the Cougar doesn't jump start. All components of the ignition system, including the starter and ignition switch, will need to be thoroughly inspected.
