Need a wiring diagram for Ford F-350 7.3 diesel/automatic starting system diagram from ignition switch to starter

Do you know what the starter relay is ? Starter Relay
The starter relay:

• is a mini ISO relay that switches power to the starter solenoid to engage the starter motor.
• receives a START signal from the ignition switch.
• is controlled by the powertrain control module (PCM).

Starter System - Operation
When the ignition switch is turned to the START position, the starter relay switches power to the starter solenoid causing the starter motor to engage as long as:

• the digital transmission range (TR) sensor is in PARK or NEUTRAL.
• the anti-theft system is operational.
• Do you know what an automotive wiring diagram is ? How to use a test light or DVOM - digital volt ohm meter .

No crank good starter how to troubleshoot any car Hyundai

free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. year , make , model an engine size . Under system click on engine , then under subsystem click on starting . Click the search button then the blue link. Looking at the diagram i see the PCM - engine computer has too energize the starter relay for the starter to engage an spin the engine . Any light's lit on the instrument cluster , security , check engine light etc..... Automatic or CVT transmission ?

Hey Opie , how are thing's in Mayberry ? Ha Ha Ha , bet you get that a lot .
The ignition will not turn over. You mean the starter will not turn over ? When you turn the key to the start position nothing happens ? The starter doesn't spin the engine .
Could be a few reasons . High resistance in the starting circuits . Do you have and know how to use a volt meter ? Doing voltage drop testing on the starter motor , cables .

Starter Voltage Drop

Looking at a wiring diagram and testing the control side of the starter circuit , relay ,ignition switch , wiring etc... Do you know what a wiring diagram is and how to read one ? Video's on youtube showing how to understand diagrams . Here is a web site for free wiring diagrams . http://www.bbbind.com/free_tsb.html
Enter vehicle info. Year , make , model and engine size. Under system click on engine ,then under subsystem click on starting . Click the search button then the blue links one at a time . Do you have a manual or automatic transmission ? Could have a bad clutch switch if manual trans or park neutral safety switch with automatic trans .
Check out some videos on basic automotive electrical testing .

You can go to this site and look up your truck, it will help you out with that install. Different company then your system, but they tell you what wires are what in the truck for hooking up your system:

1994 Ford 4630 Diesel Tractor wiring schematic for the starting system...

The ignition switch does not go to the starter solenoid . Pin 87 at the starter relay sends B+ voltage to the starter relay . Do you know what a starter relay is an how it works ? The ignition switch is an input to the PCM - engine computer . When the PCM sees this B+ voltage from the switch it energizes the starter relay sending B+ voltage to the starter solenoid . http://www.bbbind.com/free_tsb.html free wiring diagrams !

Is it automatic or manual assuming automatic for the moment
If it is automatic try to start it in ever gear by holding the ignition key all the way on and pulling the selector slowly between the ranges
If the starter catches and engine starts the inhibitor switch needs adjusting if not go to the next step which is for automatic & manuals. bridge the solenoid power wire with the main battery wire.
If this causes it to start with the ignition in the on position then manuals may have a faulty ignition switch automatics may have the inhibitor switch wires disconnected or a faulty ignition switch.
if the solenoid goes click click faulty solenoid or if no starter action happens then the the starter is cactus

prime system by switching on the ignition three times for 15 seconds each time.then operate starter maximum 30 seconds. if engine still dont start wait 5 seconds repeat the procedure.if engine does start idle rough run engine fast idle speed for one minute purge air out the lines until engine run smooth.

You can get a free wiring diagram and fusebox layouts at Autozone.com. Just register your truck on their site.

If you look at the wiring diagrams you should see that the starter lockouts and shift interlock is a separate process. Neutral is a position which allows the starter to work.

What you are having problems with is the RUN circuit on the ignition side. You could have a bad ignition switch. The switch should have an Ignition Relay in the Powerbox. If this is the Diesel, they have a KILL circuit to stop the engine that is different than a gas engine since the Diesel fires by compression.

So looking at your wiring diagram, you would be looking for a connector or component which could cut out intermittently. I am thinking more of a Relay because you have to reengerize the circuit by turning the ignition switch to OFF, before going to CRANK, and then RUN. Most of the time, the starter interlock only controls the start circuit.

Another possibility is the Antitheft. If the KEYreader loses communication with the Security system, it may stall. I know that vehicles will not start without the correct key or if an unprogrammed Blank is inserted.

I hope my solution helps.

it sounds like your ignition switch is bad have it replaced thats what sends the signal to starter as well as rest of engine to run or not run

IF YOU HAVE A POINTS TYPE DISTRIBUTER, THE WIRING WILL BE: TO ENERGIZE THE STARTER SOLENOID A LARGE, ABOUT A NUMBER 12 OR 14 GAUGE WIRE WILL GO TO THE INNER MOST SMALL TERMINAL ON THE STARTER SOLENOID. IT MAY BE PURPLE IN COLOR. THE SECOND SMALLER WIRE SHOULD GO TO THE OUTER SOLENOID TERMINAL AND GO FROM THERE TO THE + TERMINAL ON THE IGNITION COIL. THIS IS FOR BY PASSING THE RESISTOR WIRE FROM THE STARTER IGNITION SWITCH. THE LARGER BATTERY CABLE WILL GO TO THE UPPER TERMINAL ON THE STARTER SOLENOID. THERE MAY BE AN ADDITIONAL BATTERY FEED WIRE TAKE OFF FROM THE STARTER BATTERY TERMINAL POST ON THE SOLENOID FOR OTHER ACCESSORIES. THIS TYPE OF SYSTEM (POINTS TYPE) WAS TYPICALLY DONE AWAY WITH IN 1975 WHEN THE HEI DISTRIBUTOR CAME OUT.
