And this is removal manual:
Starter
Removal & Installation
1. Disconnect the negative battery cable.
2. Raise and safely support the vehicle.
3. Remove the starter terminal cover.
4. Remove the terminal nut and separate the battery starter cable from the starter motor.
5. Disconnect the solenoid (S) terminal connector, if equipped with a starter mounted solenoid.
? To disconnect the hard-shell connector from the solenoid (S) terminal, grasp the plastic shell and pull off; do not pull on the wire. Pull straight off to prevent damage to the connector and (S) terminal.
6. Remove the starter motor retaining bolts.
7. Remove the starter motor from the vehicle.
To Install:
8. Place the starter motor in position and install the starter motor retaining bolts. Tighten the bolts to 15-20 ft. lbs. (20-27 Nm).
9. Install the battery starter cable and a terminal nut to the starter motor. Tighten the terminal nuts to 79 inch lbs. (9 Nm).
10. Connect the solenoid (S) terminal connector, if equipped with a starter mounted solenoid.
11. Install the starter solenoid safety cap. If equipped.
12. Lower the vehicle.
13. Connect the negative battery cable.
Start the engine several times to check starter motor

do you hear a clicking sound at the starter.if so then the starter needs to be replaced.if not you need to check for voltage at the starter wires the small terminal as that is the wire that comes from the ignition switch,if you have power here then the starter solenoid is bad but you should change the starter anyways.

hi, first thing we need to do is DISCONNECT the BATTERY (NEGATIVE (- sign)) HEAVY LEAD.

the SOLINOID has a HEAVY POSITIVE (+) LEAD this is a BOLT on connection and also (normamlly smaller cable (this cable feeds the car POSITIVE (+)) BOTH BOLT on THE SAME terminal ( ring terminals).

the STARTER MOTOR CONNECTS to the other BOLT ON CONNECTION (SINGLE ring terminal) of the SOLINOID.

the other small wire (s) is the (ignition key position starter motor circuit, the colour RED/WHITE or BLUE/WHITE. this is normally a PUSH-ON connector. if you have a BLACK or BROWN WIRE then this is EARTH (GROUND (-))

testing if this do'nt work. check if BOLT-ON CONNECTIONS are TIGHT by HAND.

the solinoid is a remote HEAVY CONTACT SWITCH and has 2 circuits SWITCHES HEAVY CURRENT up to 700 AMPS. and the CONTOL of the KEY to operate from a small wire. gerry

Big terminal next to motor gets the ground wire. Other big terminal gets the big red hotwire from battery. The little terminal gets the white/pk wire from the starter relay/ignition switch. Always remove the neg batt terminal before hooking up starter, as you can easily get melted wire in your eye down there. I assumed you have the stock setup, but if you have a modified setup with a remote solenoid, please get back to me.

check battery terminals for corrosion. clean with a wire brush. check starter terminals for corrosion and clean as nessarray. if the connections between the wire and terminal connectors are corroded you may need to replace that wire and terminals.

Most Fords I have worked on use a solonoid. Measure the voltage on the starter motor side when you turn the key. Does it show 12v? The solonoid may be energizing but if the contacts are bad the starter won't get current. Jumping across the two large terminals will also bypass the contacts, see if this will crank the motor. Use a wire the same size as connected to the large terminals. The starter pulls hundreds of amps.

facing the front of the starter, the terminal closest to the engine is the trigger wire for the solenoid. any other small wires would generally be attached to the other small terminal if yours has one. (trigger wire is the only small one that will have full 12v with key turned to start position)

1. Disconnect the negative battery cable.
   
2. Properly raise and support the vehicle.
   

Disconnect all wires connected to the starter, including this ground wire on the starter mounting bolt stud

1. Tag and disconnect the wiring at the starter.

1. WARNING

1. When detaching the hard-shell connector at the S-terminal, grasp the plastic shell to pull it off. Do not pull on the wire itself. Ensure to pull the connector straight off to prevent damage to the connector and S-terminal. If any part of the connector is damaged, replace the damaged component.

Remove the starter motor (arrow) mounting bolts . .

Remove the starter mounting bolts and remove the starter.


. . . then remove the starter—be careful, the starter motor can be quite heavy

To install:

1. Position the starter motor against the engine and install the mounting bolts. Tighten the mounting bolts to 15–19 ft. lbs. (21–27 Nm).
   
2. Install the starter solenoid connector by pushing it straight on. Ensure that the connector locks in position with a notable click.
   

Install the starter cable nut to the starter solenoid B-terminal. Tighten the nut to 80–123 inch lbs. (9–14 Nm).

1. Connect any remaining wiring to the starter motor.
   
2. Lower the vehicle.
   
3. Connect the negative battery cable.
