No crank, no start, intermediate dash lights/gauges working, computer will not communicate with a code reader. Engine does crank by either jumping the solenoid on the starter or running a wire from the starter relay to the battery. Replaced the cylinder lock, ignition switch, ECM and crank sensor. Fuses and relays are good. I came across a YouTube video of a vehicle with the same issues and it was the fusible link. I haven't tested it yet. Could it be that or something else? Rheumatoid arthritis has made working on my car difficult and I physically can't work on it too long before I start hurting. Besides what I replaced on it; I've spent an extra $5k+ from my slicing my finger open while figuring out what's wrong. I know it's high mileage, but it's been a great vehicle.
Any information that could help would be greatly appreciated.
Thanks

I would check the ignition fuse for power while the key is on, and then check the ORG wire for power at the ignition switch. This guide will help.

Here are the fusible links. Check out the images (below). Please let us know what happens.

Did you get a chance to look at the fusible links in the main fuse panel which I included above? Sorry I forgot to mention the image was there. Here is a guide to help you test them while using the image above, with the system on please go down all of them and check the fuses as well.

Have the system on while testing.

The 40A battery feed fuse is good. I saw the image and checked. There's also an 80A bolt down style fuse outside the distribution fuse box that I checked as well. I have a Chilton repair manual that I've been looking through as well to try and figure it out, but no luck. Got a brother who's a Honda mechanic and he can't figure it out either.

I updated my first post, and I need to know if the ignition fuse has power, and if so, check for power at the orange wires going to the ignition switch. Let me know please.

Ignition fuse has power going in and out to the Ignition switch. Checked by turning on the ignition and unplugging the ignition fuse. Wasn't able to check from the switch itself. Hands are not working too well today.

I am sorry to hear about your hands, but we will need to check for power through the switch which is the next test. Let me know what you find when you can.

I'll get on checking it when this rheumatoid flare goes down. It may take another day or two. Currently I just have use of 2 fingers on my right hand and 3 on the left hand. I'll reply back as soon as I'm able to.

Good work, can you confirm power at the BCM and HVAC fuses in the fuse panel under the dash? Key on.

This means the ignition switch is working. So, to confirm no dash light come on at all when the key is turned on? Can you upload a short video of what is happening?

It's intermittent on the lights/gauges. Fuel gauge doesn't work most of the time since the no crank/no start problem started, speedo/tach moves a little bit while cranking.

Okay, let's work on the non-cranking issue. Here is a video that can help, and I have included the starter wiring diagrams so you can see how it works and to use a test light to see where you are losing power.

And this guide can help as well:

Sorry about not replying sooner. Everyone in the house had the flu. With me having rheumatoid arthritis, it took longer for me to get over it. Getting sick with an autoimmune disorder isn't pleasant. As far as I could tell, everything checked out okay. Tried to upload a video, but it wouldn't load. 1st picture is the code reader hooked up. 2nd picture is right after the key turned on. 3rd picture is right after using the key to try and crank over. I know the fuel gauge shows empty; but that's one of the intermediate gauges that isn't working. The service vehicle light is one light that came on when the issues started.

It showed failure to connect. I know it's not the reader. I got that one in December and never used it. It also wouldn't connect to 3 other readers that I tried last year.

Okay, I see now. lets check the AUX 1 OUTLET fuse in the fuse box on the left side of the engine compartment, also I have included a guide to help you check for power and ground at the data connector.

https://www.2carpros.com/articles/how-to-use-a-test-light-circuit-tester

Here are the wiring diagrams for the DATA connector as well so you can see which wires to test with the key on.

Got a new problem that showed up. Security light kicked on. Tried to turn the key on and leave it for 10 minutes(x3) to program the pass lock, but no luck. I could not find the black/white wire under the right kick panel. Ground wire on the fuse block is good.
