no fire to spark plugs, replaced distributor cap still no fire. my car wont start
When was the car last tuned up (new plugs, wires, cap and rotor, air filter, fuel filter, ignition timing checked)? Were OEM parts used for the electrical items above? If the car has been tuned up recently and all parts are OEM, then the igniter (located in the distributor housing) is a strong candidate.

Why don't you just have him replace the engine? If you're going to replace parts willy nilly with any regard to wether they need to be replaced, you might as well just replace the engine; at least that way you have a good chance of fixing the problem. P.S. the coil is far more likely to die than the ignitor. However, I'd check the engine computer for codes before doing anything.
I did not suggest replacing any parts at this time, son. I am collecting information. No spark is more likely to be the igniter, and I'd say the chances are about even of either dying. I am pretty sure a dead coil or dead igniter won't set codes on a 91.
When you crank, does the tach needle jump up and down a tiny bit? If it's perfectly still while you crank, then your igniter is dead. If it jiggles a bit, then the igniter's fine. How old are the plugs and wires? When did this problem start? Was it sudden or has it been happening for some time? What events immediately preceded onset of the problem?
