Car won’t start

Check the solenoid on the passenger fender area. Use a $5 dollar Test Light you can buy from Harbor Freight or an auto parts store. Have a friend turn the key to start and you should see the light glow on the Test Light. You can use a length of 18 gauge to 12 gauge wire to jumper from the + Terminal of the battery to where the solenoid is. Check that the solenoid clicks. Verify wire connections from the solenoid back to the fire wall. Best of Luck, Sir

See answer here http://ricksfreeautorepairadvice.com/ford-escape-no-start/ Ford uses an antitheft system to tell the PCM to energize a starter relay located in the battery Junction box. The image shown here is from a 2008 Ford Escape, Mercury Mariner. So your first job is to find out whether the no start problem is due to a bad relay or some other component or wiring harness. The easiest way to test the starter relay is to locate it in the battery junction box and find another relay in that same junction box that has the same part number or same size and swap the relays. If the engine starts, you’ve nailed it down to a bad starter relay. If not, you’ll want to check for power going to the starter relay contacts and the relay control coil.
