Ok, i bought a 81' RX-7 yesterday for $500.00, the guy had told me it hits and misses, so whatever, i went to go start it and no go. Checked the spark, none on the leading, and the trailing is fine. Wires, Plugs, Dis. cap and rotor are brand new, coils are new. Checked the power to the coils both are getting power (compared the wires of them both btw each other). But is in decent shape the body is in better then the one i bought a couple weeks ago, is a 83' RX-7 but got it for $2150.00, the engine was rebuilt in this one and it goes real good like, some pretty bad rust holes in the rear wells though, but the interior is in pretty good shape.

One other question, the tach. in the 83' doesnt work. Its getting power, i can tell that it is becuase when I turn the key on it twiches a bit. All the fuses are good, checked them twice or thrice times.

Anyways im going to go mess around with the 81' to see what i can do to get it going. Perhaps switch the wires from the one coil to the other and see what happens.

K i got the 81' running, turns out the one wire was on the wrong plug, so yeah i changed that, but it still doesnt spark on the trailing coil i belive, but it runs, and the tach. works on this one. So i switched those wires at the distributor, the one has a blue connector with two wires and the other with white con. and two wires, the transistor or what looks like a transistor that the white one was originally connected to ( closest to the carb and rat nest.) i took that connector off and the engine still runs, so i switched the connectors, and the one doesnt work at all. So I think that its that transistor looking deal that runs into the distributor that is the problem, i hope not cuase its most likely a pricey som biatch.

Any comments feel free to let em rip. And sorry to the guy who i originaly posted my ***** above onto his thread, i was clicking on the wrong deal at the top of the page and its like you cant add threads to this thing, but yeah i found out that it wasnt that, so now i know guys. Anyways im out, cleanin the carhole, so i can bring the black beauty home and get it looking and running good again.

all right..wich chuncks are u talking about. Are you talking about the black things on the side? There called ignitors. And then there is like a single little wire that runs down to the dizzy, that is..im not to sure.. aint had to screw with it yet.

But im roughly haveing the same problem. And in my experience its the ignitor. It controls the tach, as well as the trailing spark plugs.

greeddennis

So if i have to replace this Ignitor, what kind of price am I lookin at from like say, Napa, or some auto parts store ? And by the way that little single black wire running to the dizzy goes to a capacitor. Thats what that little ***** is.

zduford

yeah thouhght so about the cap.

An ignitor new, is about 500 bux or so, but im sure you could get one from some one on here for a hell of alot cheaper.

It does sound like a bad ignitor. They are quite expensive new (around $180 each). You are best off getting some used ones. Check the 1st gen for sale section on here or ebay. You can usually pick them up for around $15 or so used. Get at least 2 if you can. It is always good to keep a spare one in the glove box. You never know when one will fail.

They also are very easy to remove. Only takes a phillips screwdriver and are mounted with 2 screws. Then, they simply unplug. They are also very small and just so happen to fit into pockets...... Er, yeah. Anyways, the trailing one - the alternator is in the way but if you happen to find a donor car, the leading one (not the one behind alt) will come right out. Good luck getting it running right.

Allright guys, i solved the Tach. problem, it was the wires on the initors they were backwards. So i switched those around and then switched the coil to distributor ones around, and vuola it worked tach. works and runs beautifly.

Ok this is were im stumped still, with those ignitors.... so today i changed the ignitior from my working 83' and put it into the 81' no dice, it didnt even try to fire. Checked the leading sparkplug and no spark, then i tired striaght off the coils and nothing at all, **** i had the car running last night, and now theres nothing. Also i did the rat nest removal, pretty good instructions i have to say, and sure cleans up the engine bay and removes that ugly *** air pump, so yah thats the only thing i done to it. Thanks to the guys who made the tutorial it made doing it pretty easy.

And to make things even more confusing, i took the ignitor that wasnt working (trailing) from the 81' and stuffed it in the working 83' and what happens, the damn thing runs perfectly fine, so could It be the pick up coil, and if i can test it, what resistance is it suposed to be?

I have brand new coils, plugs, distributor, and rotor.

Thanks for the help.
