1988 blazer, no spark?

The distributor module in those controls fire to the distributor of course, but also to the fuel pump. So, when they go out, you will not hear the fuel pump kick on. That's how I always verified it was a module. No fire plus no fuel and the module always fixed it for me 100% of the time.

I don't know what you could have done spraying the reluctor. It will fail to start, again, I bet.
