When you installed the new ignition switch did you line it up with the pin like the book said it should be done.
Read this link and do as it said for testing https://www.ford-trucks.com/forums/1...w-starter.html
Also what motor & transmission dose the truck have?
How do you have the starter button hooked up that it cranks?

My rookie thought is the starter solenoid. Bad contacts can weld themselves together and keep the starter spinning after releasing the key/remote switch. When you turn the key, if you're truck is like many others, the wiring does not function as well as new. The key may not be sending a ton of current to the solenoid. If the contacts are weak, it may not get the start signal. But using the remote will give a stronger signal (more current and volts) engaging the solenoid. Solenoids are cheap and easy to swap. Anyway, that's where I would start.

If he had the button hooked to the battery + and the small S lug and it turned over then he would be looking from the IGN switch to the solenoid.
If it still did the same "no crank" then it would be a bad battery cable connection in my book.
BTW to others you can not look at battery cables and tell if they are bad or not unless you are super man.
Me if they are of unknown age and look even a little bad I replace them all.
Just get the largest gauge cables you can get.

And needs a fully charged battery.
I would think if the solenoid was "welded" then as soon as he hooks the battery back up it would start to crank and I did not get that from reading his post or I missed that.

Let me read it all again ........
Ok, with the key dash lights go dim and nothing. With button it keeps cranking till battery cable is pulled off.
Is this with the key turned on to run or off? Wire still on the S lug?
If key to run turn it to off and try again. Still cranks then unplug the IGN switch and try again.
If it dose not keep cranking then you wired the plug to the switch wrong when you replaced the IGN plug.
Yes the solenoid could be bad but dont go buying one just yet.
Maybe we should back up and ask what was the problem that you replaced all the parts, IGN switch & plug, IGN box and key cly?
This may point us to what was wrong to start with before the parts were replaced that did not fix it.
