Question about 1985 Mazda RX-7
I removed plug wires from coil distributor and plugs and lost paper i wrote it down on, this is a 1985 12a motor
Quite easy actually. There are two rotors 1 - front and 2 - rear. there are two plugs per rotor Trailing - top and Leading - lower.
The distributor cap has letters and combination letters/numbers on it (if it does not you need to get a good quality cap) L and T and L1 T1 L2 T2
L is leading coil, T trail coil, pretty self explanatory from there
My recommendation from nearly 40 experience with rotary's is to use Mazda Mitsubishi Cap Rotor and NGK wires and plugs. Has been good enough for factory race teams also.
An issue with most aftermarket rotors is that they do not fit properly and can cause changes in timing and worse case, damage both cap and rotor.

SOURCE: No spark?
Hi, common thing with the mazda was the coil or the ignition amplifier going faulty, both of which are located within the distributor, the coil ususally gives the symptoms you describe, a weak spark. The coil is the most common failure aswell for your vehicle i would recommend a new one, also make sure distributor is spinning as it could just be a case of a broken timing belt.
Good luck Davelee

any wires not plugged into there respective places, any sensors the old engine had that this one don't, did you use the old distributor for your coil setup,I think it might be, luck
