Does the starter turn the engine over? Do you hear any noise at all when you turn the key?
If it runs after you pop the clutch, then it's nothing to do with your ignition system. Generally speaking the "ignition system" consists of your distributor, ignition wires, plugs and coil.
You'll find posts on here about a classic 914 issue with the start switch (the key) not activating the starter when it's turned so that's something to check out too.
However, if you're replacing ignition parts, I'd recommend some type of electronic ignition. I'm running the Pertronix ignitor with a MSD ignition system. Running electronic ignition generally requires replacing the coil, so if you're going to spend money on a coil, you might want to go with the electronic iginition now. You'll read lots of posts going both ways on Pertronix ignitors--mine installed easily, and works great with the MSD system. I've been running it over a year IIRC, and have had absolutely no issues. When I time the engine now, the timing mark is rock steady under a timing light as opposed to the OEM ignition where the timing mark jumped around somewhat. A jumpy timing mark indicates worn distributor shaft bushings (like, who doesn't have that?). It affects the opening position of the points, and therefore the actual spark advance. Since the Pertronix fires based on a hall effect sensor, the distributor shaft wear doesn't seem to be an issue. With the electronic ignition I definitiely see a difference in engine performance with a smoother idle and more power below 3000 rpms.
And that's all I have to say about that.
