C10 Silverado cranks but won't start

I pulled some of the plug wires and I am getting spark.

Thanks for posting back w/the result OP. Glad you got your Silver Fox back on the road.

Just curious if you have a theory why you were seeing a good spark though, since it seems to have been the ignition system. Do you think it was an intermittent coil failure, and you happened to be testing for spark when the coil was working?
