The large connectors are the ones iam concerned with I only see the white and the grey connectors in the pics but not the black one?What iam looking at is the terminal opens where they go into and connect to the fuse box terminals they shouldn't be open. They should be closed so make a good connection. In the pics some of them look open compared to others in the pics do you see what iam talking about?

No, I don't see them to be open to the point of not connecting, but I'll take it apart again and have another look. I didn't bother with the black (large) connectors because I checked the fuses across the top and have power on both sides, and that would indicate a good connection, wouldn't it? I'll have another look to check if they are open too much, but I doubt that the terminals are the fault. The only reason to question them was the fact that I did (once upon a time) get life at the guage and the pump. But only once. Might that just have been a coincidence?
What would be the common cause of no spark, an empty indication on the fuel guage, and the security light staying on only for a few seconds after the key is turned on?

Okay, just opened it up again, black connector photo attached. Should I try to bend some of the pins?

I call it more then coindencie most likely a poor connection or bad fuse box I have seen a few bad fuse boxes here and there. There really isnt any common reasons for all those things to go wrong.I really wish I was there to help you out you cant see the terminals that are open more then the other ones?They should all look closed. What I do is take a little pick and insert it where the terminal starts to bend and go back down into the terminal.I bend it closed on one side of the bend and then the other side. Also when the bolts holding the connectors in arent tight causes issues also.

I did try to open some of the pins, almost impossible to get something in to open them up. I tried to remove a pin through the bottom to make it easier to spread, but couldn't get the pin to release. I pulled the blue plastic pin holder, still was unable to push the pin out. What a PITA. I will open the box again and try harder to spread the pins some. I even used an ice pick, and even that was too big to get into it to spread it open. Will give it another try.

I opened the fuse box and used a tiny flat screwdriver to pry open any of the pins that looked to be a problem, put everything back together, and nothing has changed. Still no fuel guage, no fuel pump action, no spark. We touched on this before, how about the CPI? I read that it controls the entire starting sequence. You said it might be a bad fuse box, should I go to the junk yard and pull one tomorrow? Along with a CPI? Another BCM?

For whatever it's worth, I went to the junk yard today and bought a very clean fuse box, complete with all the fuses and relays. Removed the original one and installed the new, and nothing. No improvement. Should I give up on this?

Alright while cranking the engine do you have power out of the grey wire from the underhood fuse box?Also do you have a constant power to both sides of the fuel pump fuse?

Welcome back. I checked and there is power at the fuel pump, while cranking and also while at rest. I noted this last week, but unsure of what you mean by "to both sides". With the fuse in place there is power to both sides, but not when the fuse is removed. Isn't that the way it's supposed to be?
As for the "grey wire from the under hood fuse box", I see two grey wires, one goes to the 10amp fuse that reads Injector (L4), the other to Controls IGN 1. They both show power while cranking and also when not cranking but with the key in the on position. Can't remember if I mentioned that I can get the pump to come alive if I jump the relay.

So the grey wire has power all the time at the inline connector back by the gas tank?If so the fuel fuel pump would be running all the time if your ground to the fuel pump was good
Have you checked the actual fuel pressure yet?
