Where/how did you check for spark?

Re: 96 Chevy Suburban wont start
Try using a spark tester. At atmospheric pressure, it doesn't take much voltage to jump .060", but at 150 PSI it takes much more voltage because the air is denser and becomes a better insulator.
You could also use a timing light to check if the actual plug is sparking while in the cylinder and cranking. If you determine there is no spark, check the crankshaft position sensor.
