Ok, remember yesterday i had put in my spark plugs with air tools, and one of them didn't go in all the way, and went in sideways, well today, after about 3 hours of trying, i put some motor grease on the thread of the plug, and inserted it straight into the hole, it didn't go all the way in, but its very tight, it went about 3/4ths of the way in, but my neighbor said it wouldln't be much trouble, yet i thought i had soved my starting problem but still nothing. I ut a test light to the ground of my battery and tsted the black plug with the yello stripe on my lead coil and it lit up, but it still won't start, and my tach won't move, what can it be?

Whacked ECU. Test light are ECU killers. Check for the five volts reference voltage on the brown/white wire on the boost/pressure sensor (with a digital volt meter). Note: this is my last thoughts on this subject ....ever. Good luck. You'll need it.

Did this problem start with the changing of the plugs?
If so, you probably knocked a wire loose around the coils.
Check your fuses right behind the battery.
Does it crank on the starter? Give us some more info if you want good advice.
Your plug repair IS NOT SATISFACTORY!!
Do Not drive it until you get the hole rethreaded or a heli-coil put in. Or you will be buying a new motor.

ok, thanks, i won't, and the problem began hen i was taking apart my intke manifold, whe put it back together, i thik i pligged everything back, but i must have donesomething because it cranks but it won't start. I don't even see it spark, i mean i stuck a scredriver in the leading ignitor pack and put the plug wire nextto it, and it used to spark, enough to shock me, now nothing. what do you think?

by the way, why is my plug fix not satisfactory, i trust you, i jus wanna now why, i mean it went in really tight, and i figure its not gonna damage compression, how come?

Your plug only went in partway, right?
OK, the factory decided how many threads on the plug were needed to hold it in effectively AND transfer heat from the plug. (volume of surface area allowing metal to metal contact has been reduced in your engine)
Now you have screwed the plug into the weakened threads, and not into the good threads that are deeper in.
Think about it.
Will this hold, or blow out the plug and ruin that part of your engine casing?
Will the plug overheat and drop debris into the engine, thereby trashing your rotor tip seals?
Do you really want to ignore the design parameters of this beautiful engine?
Regarding the not starting issue:
It seems logical that something you touched is not back together correctly.
Vacuum leak? Wrong vacuum hose connection? Something left off? Loose wiring connector or plugged into the wrong place? Did you blow a fuse?
The list is endless, almost impossible to diagnose long distance.
You may have to bite the bullet and get help.
Good luck!!
You live in Miami, right?
Contact the local RX-7 club. They have some really sharp people there. Ask nice and you might get some free help.

Ive heard of airflow meters killing the spark when not properly connected. Have you checked to see if the plug is in all the way?

I just did a search on this site, with MIAMI as the key word.
These members names popped up. Their profiles show Miami or Ft Lauderdale. (You could have done this)

Mazdarx7racer - What part of Miami are you in?

MazdaRx7Racer4Life

7Rebel

I'm on the other side of the airport ...nw 7th street.

I'm no expert but I just did have my upper intake off and thought maybe I could help if I was closer. I think MaxRx7 lives near you. Maybe he can help you out. It seems like he knows his cars.

drive it to a mechanic to rethread your holes. considering your car is somewhat running.
