Problem with the starter. Possibly locked up, or shorted out. Remove and test the starter.
Why does it really matter? Are you going to test this out? You're sick.
Not that hard, it's located on the back side of the motor. Make sure it's the starter. You can test it with a remote starter. My car has the problem with the ignition, because it started when I hooked up the remote.
Make sure truck is in neutral jump across small (trigger) terminal and cable that runs to starter if vehicle "turns over" relay is bad
Have the coolant system pressure tested, the pressure test will increase the coolant leak.
Usually you can bang on the starter with a hammer when it doesnt want to start and that will do the trick. It will engage and the car will start. If that is the case then the problem is the starter itself and not the solenoid. You can also remove both and take it into any Kragens or autozone and they will bench test it for free and tell you. You can also use the screw drive method by bypassing the solenoid and applying power directly to the started by laying it across the 2 terminals. if it starts then the solenoid is the problem assuming you have power to it.
I'm not a fan of Ford, personally, but Ford has really upped their game in the past few years, and the quality of their vehicles is much better now. The sixth generation Taurus gets good reviews, has a good power-to-weight ratio, and gets excellent crash test safety ratings. But remember, a car can only be as good as how it's maintained.
You can use a wire instead of the starter to test the tubes .. I did it, it works !
The Data Link Connector for the 2004 Ford Escape is located on the lower left side of the dash. If you sort of stick your head under there and look up, you can't miss it!
Remove the starter and take it to an auto parts store. They have the equipment to test it.
The check engine light will illuminate and you will fail an emissions test.
Remove starter and bench test See if you are getting power to starter
