ANOTHER UPDATE!!!
It actually happen any time I move the engine or transmission to the left...I was pulling left on the engine itself and it would click back and fourth.
it is nothing to do with the harness, though, because I wiggled every wire under the hood, Including the main power, main ground, any small gounds i could reach and the battery power to the starter and nothing. it has something to do with engine movement.
Any ideas?

I'm having the same problem here, turbo timer goes on and off as i crank so as the dash, i guess is an RX virus or something, it happend after i connected the battery the wrong way and blew the main fuse, change the fuse and now i got this problem. https://www.rx7club.com/2nd-generation-specific-1986-1992-17/crazy-electrical-problem-car-wont-start-491159/

need help
I really like the video I now just saw it New plugs and some atf into each leading hole with a sqiurt can and then crank it with it on the floor (yes it will smoke badly for a while ) but it should start if you have the cas timied correctly and there enough compression . I`ve not read all of this and I`am not going to the electrical part looks like some faulty wiring job make sure all connection are tight on grounds make sure it is a good ground. I`ve seen a lot of bad wiring jobs.

It only happens when i pull the shifter (in neutral) all the way to the left. It doesnt happen in any gear, or reverse. Only when I pull the shifter all the way to the left...What does this mean?

it must be a ground near the starter or the near the intake manifold or from the tranny to the firewall.
In the video all the lights flicker ON once the engine tries to start but then they go out and the engine starts to sound flooded. The process repeats its self. Check all your grounds. There are a few wires atleast on my n/a manual tranny to a sensor at the top of the tranny near the shifter. I dont know what would happen if though came loose.

The Short COULD be in the harness.
Soudns to me like somewhere in the line to somethign a connection is being made intermittently.
Moving everything to the left could be causing the stress on the harness or wire where ever it is, causing the connection to go out.
Seems to me like the vibration in your car is causing the fuckup.
You ahve taken the thign apart many times i'm sure, you could have puleld somethign int he harness etc the last time you did it.
Connections being good only means you're halfway there.
I'd find the most sensitive spot when you move thigns to left, and check around that area. Or, have someone shake parts of the harness when the car is in the on position.

Ok...lets break this down.
1. All your accesary **** works periodically.
2. ignition spark is come and go. (working periodically)
3. As your cranking the car **** come and goes. (see 1 and 2)
Now all these systems have a power and a ground. But they seperate their circuits fairly well on the positive side. But one thing they all share universally is a ground. So for these thing to be acting a ground is either off, shorted, loose, or whatever else you can come up. This is fairly evident in the flicker caused in the movement of the engine and tranny. As they shift their pulling on that ground or putting tension on something that is putting tension on the ground. Now for this ground to effect the whole damn car says that its a major ground. Start at the negative terminal of your battery and go from there. Work through the whole ground system. Leave no stone unturned.
Disclaimer: I could be wrong. All I'm going on is a video and some words. Hard to diagnose a car thats a lot of miles away.

Thanks, ForsakenRX7, for all the help...I'll be looking into it deeper on my next day off, and I'll let you all know how it works out. Thanks alot

Electrical, for sure... No worries.. Start by pulling the fuses to every subsystem. Put an ammeter in line with battery load. Then re-insert fuses until you find a load. Then trace that system. Additionally to get the car started I would remove all non engine subsystem fuses. then try to start it up. If both of these fail analize the engine system wires/fuses etc.

Wanna, I assume it bolts to the exhaust or somewhere else down there, I can't really see where the cord runs, I've heard there are grounds on the exhaust so I assume that it was the strap that leads to it.

hmm...I'll look into it...my exhaust is all aftermarket with the exception of the turbo manifold.
How about this firewall ground? This isnt the same one on the drivers side strut tower is it? Where is the firewall ground?

have you checked the stupid little 30 amp fuse labled engine or something like that? i popped that fuse somehow installing my sound system and it stumped me for hours and my car did exactly what yours is doong. switched the fuse and the car ran perfectly. the load you are putting on the car with all those accessories could have messed up your ecu too. try swapping out ecu's just for fun to see if it changes anything. last thing is that in the vid it really seems like your timing is out. that first crank sounds like your plugs fired way too early

the firewall ground is near the wiper motor on the passenger side. It goes straigh to the back of the engine. I forget if it goes to the tranny or to the rear of the engine. This is an important ground in some vehicals.
Also check the grounds under the trailing coil. About 10 ground wires i think go to a small plug unthe trailing coil.
Check the grounds to the engine as well (IE all grounds the connect to the block or intake manifold.
Also, Check the grounds near the ECU on the right side of the foot well. You will need to remove some molding for this.

I found it! when I ground out the TB intake elbow (for the fmic) to the brake distribution block everything works correctly...does this mean I'm missing a ground on the Intake?

Ok...that worked...grounded from the TB elbow bolt to the one of the trailing coil mounting bolts...it works perfect now...but I still think my timing is off...or I'm flooded, or both...I am getting rapid pops out of the exhaust, and it almost sounds like it wants to start, but it doenst quite kick hard enough to start
