My mmechanic dad says try replacing the plugs, I would give it a tune up. If this problem persists you and try out fixing any of the following:
- Faulty battery /and or Faulty Battery connections. Like with corrosion or a dead battery if it doesnt rotate.
- Automatic Transmission not engaged in Park (P) or Neutral (N).
- Broken, loose or disconnected wires in the starting circuit. Inspect all wires and connectors at the battery, starter relay, and ignition switch (on steering Column).
- Starter Motor Pinion jammed in driveplate ring gear. Remove starter and inspect pinion and driveplate.
These suggestions are comming from the repair manual, I have mine for my taurus. They cost about 30 bucks off of AutoZone, but you might get it cheaper on Amazon. Here is a easier list of other problems you can check - my Taurus has problems often and its only 9 years old -
(the first two is probably one of the ain causes, usually these two need to be fix/replaced when vehicles get old).
-Starter Motor faulty
-starter relay faulty
-ignition switch faulty
-Transmission Range (TR) Sensor out of adjustment or defective.
