96 F150 no crank, no start
Hello friends, I have a 96 F150 4.9 L, inline 6, 300, with the smog system, and 150,000 miles on it.
So, I'm gonna run up to the store right quick, hop in the truck and I noticed my wife parked crooked. Turn the truck off, get in her car and straighten it up. We live in a townhouse complex and her back end probably would have gotten hit. So I jump back in the truck, turn the key and nothing. Tried to jump it and still nothing. So here is the list of what I have done:
new battery, starter, starter relay, oil pump, distributor, plugs and plug wires, ignition coil, ignition module, computer, ignition switch, fuel filter, and inertia switch. All that to say still no crank, no start. Please help. I am at my wits end.

Do you have access to a test light or voltmeter?
Next, do the headlights come on when turned on? This would tell us the ground and fusible link for them are good.
There are a few fusible links that take power from the hot terminal that the battery positive connects to on the starter relay.which is mounted on the firewall.
With a test light you can verify if power is available before and after the fusible links. if you gently pull on them a good link will not have any give where as an open link will feel like a rubber band. Let us know what you find and we can go from there. If you find a fusible link is opened, there is a reason and we need to do the right thing to avoid addl problems.

A little FYI,
There are different rated fusible links. They may not all be the same depending on what components they protect.
Did you verify which one was defective if that was the problem.? You cannot jump to conclusions with these things because you could create more problems than you solve.
You replaced a lot of parts, and I can only hope you installed them correctly.
If for example the distributor was not installed exactly as required, that could prevent it from starting once you get power to the starter
Did you replace the plug wires one at a time to prevent mixing them up , that could prevent it from starting.
Until we solve the problem of no power to the engine, we should not replace parts because now it is possible to create other problems.

Status update
I took y'alls advice and because my fusible links looked like doodoo, I changed the 2 lines that were literay melted together. The good news is I am back to clicking when I turn the key. So please keep the advice coming.

Hi Charlies,
I realize you are VERY anxious to get the truck started,I understand.!
A little more FYI,
The fusible links allow more current to pass than a fuse that would blow instantly and are there to prevent a fire from starting.
What we need to do now is to separate the fusible links and hook them up one at a time and if careful see which one gets hot. If you can tell us the color of the wire that the fusible link is connected to and then we can proceed to track down the short or excessive current in the circuit.. Also, if you don't connect the link that gets hot, let us know what is not working and that should give us some idea where to look, OK?
Wiring diagrams are nice to have access to and maybe we can help there.
If someone held the key in the start position too long, that might be why one link got hot, don;t know.
DO YOU KNOW WHERE THE CLICKING IS COMING FROM ?

There should be no kind of noise coming from the alt.
This is what you might try,
Remove the battery negative cable from the battery.
Remove the plug from the alt.
Remove the heavy gauge wire from the alt and either tape the end or wrap something around it so it can' touch anything.
Reinstall the battery cable and see what you get.
