my car was running good been running good for awhile and now it wont. weve changed the coil, the points and condenser, the spark plugs and the spark plug wires, the car is getting spark, fuel, air, and compression, dont know what else to check. any ideas?

Have you try the starter?

Does the car have a carb or fuel injection?

Running good for awhile..how long? Does it try to start? Something changed. Too much fuel, timing, low compression, These engines can run on 3 cylinders so it is "across the board" kind of problem. If you have points then you have carbs, put the old plugs back in dry and see if they get soaked, it's to hard to see it on new plugs. Might be the chokes stuck all the way down, make sure they work. Maybe the distributor moved and the timing is way off.

You said the engine is getting spark. When you couldn't start the engine . tell us in order what you did to find the problem. Since you have done a bunch of things we need to eliminate some stuff. Is this a stock dist of after market? What year Z is this.

Was the engine ok before you started working on it ?

If your getting good spark, as well as proper fuel, air and compression, the only other major thing that would keep the car from running would be ignition timing. If the spark isn't firing when it should, the car won't run.

But you need to provide more info to get really good answers.
