I wasn't able to find a similar question so,...  coil tests good but I'm not getting any spark at the plug. My distributor is the Hitachi with hold-down screws instead of clips and a screw in the rotor post. I can't seem to find a model # on it or an exploded view of this type. Are these rebuild-able and does anyone know where I can get a diagram?

It is a Hitachi D4Pxx-xx w/the same CAS as these.

Got spark at the coil wire?

yes, coil tests good but no spark at the plug. I found a possible replacement for the distributor (I'm assuming the components toasted are internal being an electronic dist.) Checked grounds, fuses, etc. unless I'm missing an external module or whatnot...

If you have spark at the coil,but,not the plugs,then you have a bad distributor cap,rotor or plug wires.

I found suitable replacements for the distributor and coil and swapped them out, it starts and runs like a different car. I believe the distributor was failing for a few years and I didn't know what it was (270k miles blurs simple diagnostics in the generalized wear), but quite a noticeable improvement. Thanks to all

thank you naru2, that's the monster for sure, I am glad I won't have to rebuild it though, I'm at the age my resistance to turning a wrench is much worse than the actual doing it
