[V8] Hello (again), and maybe some advice?

[Bryan Kamerer]

Tony,

Thanks for the help.  I'm not familiar with this problem.  It creates this
condition - sudden loss of spark and fuel?

Is it usually preceded by any symptoms?  Or it just goes and that is that?
I inquired at a newer forum - I think AudiWorld, and had the same
suggestions from a V8 owner in NJ (maybe he's on here, too).

Which pins do I check resistance on to verify - the ones under the
distributor (grr... I do know how hard it is to get down there).  Boy, that
sounds like a fun Saturday project.

Bryan
