Will not start only a single click

These were the things I got from the man car that was starting and driving without any issues but with the man car I got something very different in that power center.

These are the things I got from the man car that was not starting.

Same thing happens to the PCM circuit where there DC there was no DC in the car that was not starting for example the 5 wire connector had 1 earth that is black wire and blue with ignition current but the other 3 I didn't have anything either ignition, DC nor ground but in the car that wasn't starting I got 4 ignition on the other wires but no earth on the black wire.

Please sir help me, what's the cause and solution to this car problem? I want the car to start what are you advising me to do?

That's what I have noticed today. Please what's the cause and solution to the problem?

Today I have traced that wire and it goes directly to the starter motor. Please can you send me the factory starting system wiring diagram for that car?

At last, I noticed that some wires that when to coil were shorted to each other. However, there was still no power to the injector circuit. I suspected that the power center had an issue and not a wrong wiring because, there was virtually none.

As you can see from the video there was no power at fuses 26 and 37, brown/orange wire too was not receiving power except I bypass current to shorting link 12.

This is what I noticed from the aftermarket fuse box that I later replaced yesterday with the one that came with the car. Please note sir that this other aftermarket I inserted has power to fuse 37 without any bypass of current as well as at the shorting link 12. But there was no power to fuse 26 except I swapped the tester location from negative to positive before power gets to that fuse 26. But in the previously inserted fuse box it was not so.
In addition, the blue/red wire I noticed is activating the fusible link 19 with my tester at battery negative and testing that wire. Please, what can I do next?

Please sir, assist me more with what I can do to fix that car problem. Looking forward to your reply. Thank you.

Thank you so much for your response.

I will give you a feedback when I check that.

Good evening, sir. Thank you once more for your response. I pulled out the ECM and checked there was actually lots of short to ground therein and few wires breached with each other which I corrected. In addition, I noticed that "there was no ignition current at all in the fuse box, " but the dashboard lights were coming "on" with key "on" which is proper. The fuse box itself didn't transfer power to fuse 26 and 37 that were responsible for transferring current to the injector circuit with ignition switch turned to "on" position. Hence, I told the car owner that the fuse box too will require replacement. And when he purchased it from a store the was current there at the fuses but not to the injector circuit. I noticed that some pins in the fuse box that was powering fuses 26 and 37 were completely pulled out.
Also, I noticed that instead of Fuse 26 to be powered with test light on ground it was rather powered with test light on battery positive. Please sir, help me out with what I can do next to fix the car problem permanently.

But I noticed something else that made me flabbergasted, which I will need your assistance please. When I got an aftermarket fuse box and install it to the car without any further repair done by me, I saw something remarkable, the fuse 26 and 37 that I highlighted before in the older fuse box didn't have current nor ground to it, with the new one installed the was current to fuse 37 while fuse 26 didn't have current to it using my test light except I swapped the test light from battery negative terminal to positive before it lost the test light. But in the older fuse box there was no current nor ground at those fuses 26 and 37. Please sir, what should I do next?

This test I noticed from another aftermarket fuse box without any repairs done by me, just replaced the fuse box and current started getting to the fuse as seen there in the video.
But some pins in this particular fuse box were not intact which I didn't notice until I pulled out some of those fuses and found out that the hole for the fuse was empty.
Please do I need to replace it with a better Fuse box?

From the video I didn't do anything like bypassing of current or any connections. It was only replacement of fuse box with an aftermarket one before current got to that fuse.
