Just trying to cover all the possible senarios, fuel compression spark at the right time, take one out and the car will not run,.
just thinking back when my nephew swapped motors his engine would not run, he checked everithing like you are doing and ended up putting a new set of plugs and the car started right up, he may have it in one of his treads btabor look it up if you have some time or pm him

Okay everyone, after tons of testing and troubleshooting it's a spark issue not a fuel issue. I have intermittent spark and I traced it to the black/white wire on the coil harness. For anyone wondering it's seen on this diagram page 8 pin 2I.

I got my car to run perfectly by running a wire from this pin to a ground on my car. However, if you look at the diagram you'll see that this ground also runs to the tach gauge. Consequently, by only running a wire to my chassis I don't have a tach on my dash.
the issue I am now dealing with now is I can't find where the break in my ground is to get back my coil ground and my tach ground. I understand according to the diagram they ground under the brake master cylinder but I already checked and cleaned this connection. I think my loose connection is somewhere under the dash.
I have the dash out of my car right now, does anyone know where to check for this ground connection?

For anyone reading this I'm a idiot. I read this wrong and I tore my dash apart and put it back together for nothing.
Check the simple stuff first, Fab9 screwed me. After putting everything back together my car still wouldn't run with intermittent spark. After switching with a stock coil pack, and the original spark plugs my car fired right up......
After only 400 miles my Fab9 cops are somehow done? I mounted their driver to the firewall and followed every set of instructions but no use. After reading people's advice I know I shouldn't of bought Fab9 cops. My engine revs better and seems much more responsive with the STOCK coil pack.
I was just trying to go for a plug and play option but after diving into the wiring it's pretty simple. Either follow the guides on here for Toyota cops or the gm cops it looks like. Or heck, stick with stock over Fab9 coils. I'm not sure what my neck step is, I hope Fab9 will work with me.

Update: AGAIN, my miata is dead. I was driving down the road when suddenly the car just died. Luckily it was just down the road from my house so I flat towed it home (with a mini van.) However, now it won't start again. I'm pretty sure its spark again. I'm sad, I rove my 1990 short nose crank that was beat up for 6 months no problems. Now I can't even drive this thing a block down the street without it breaking. :'( :'( :'(

I'm running a MS labs ms2 ecu, i have fuel, spark is the problem.. again. Switched out to a stock coil pack, still nothing. Sounds like only 1 cylinder is firing intermittently.
I realize now fab 9 cops suck after having a lot of problems, but after emailing them it looks like I'm not going to get my money back and I don't have the money to switch to LS coils even though that's what I want to do right now.
