Coil or Distributor?

[Chevyholic]

Hey guys,

Yesterday I was driving along and when approaching the left turn lane at an intersection, my truck died and wouldn't restart. I have good compression, and I can see fuel being delivered to the carb, so I have to assume I'm not getting spark. I turns over just won't fire.

I'm kind of thinking that since it was running fine that maybe the gear that slips down into the engine got sheared off, but am trying to avoid removing everything until I know for sure.

So, is there a straightforward way to troubleshoot coil vs. distributor for spark purposes? Plugs and wires are both new ~4-500 miles on them, so I think the problem is in the distributor/coil.

Any ideas?

Oh yeah, its a 350 with Accel HEI.

Thanks!
David
