Intermittent Ignition Problems

Hi all,

I posted a month or so ago with what I thought was a WUR problem (search: WUR Problems???) but it looks like I am not getting spark when the car won't start. I pulled the coil wire off the distributor cap and when I put it near a ground and cranked the engine I get no spark at all. The car will start up from cold, but as soon as it gets warm it konks out and that's all until it is cold again.

Where is the best place to start looking for problems?

I have been told to look at the overboost relay (although that seems like it would be more related to fuel) and the coil as these can be problematic. What about the Permatune box? How do I check these for function without being able to swap in vetted pieces from another car?

Thanks - Jon
