Check for spark by removing one of the plug wires from a spark plug and installing one of your old plugs in the removed wire (leave the other end of the wire attached to the cap). Rest the exposed plug on an under-hood surface that will provide a sufficientground and have some one turn over the engine. You should se a strong blue spark. We have seen some intermittent coil problems on your generation Blazer that would explain a lack of spark. Good luck!
Disconnect the wires and take pictures with cell phone for reference to ensure you don't cross them when reinstalling the new distributor cap. Remove the two torque screws in the distributor cap and remove the distributor cap to access the rotor. Remove the rotor by lifting straight up and inspect the distributor for any condensation and corrosion. Clean the breather screen at the bottom of the distributor before installing the new rotor which just slides back in place. Install the new distributor cap and tighten the new torque screws, make sure you do not over torque the screws since the distributor housing is plastic and prone to stripping. Reattach the spark plug wires and start the engine and idle for 5 min and go for a test drive. Good luck and you may want to also buy spark plug boot lubricant to ensure the spark plug wires are fully installed when placed back on the new distributor cap and recheck connections after test drive. Keep me posted, be glad to know your blazer is running 100% and please rate.
If your engine timing is good, (meaning the cam is timed to the crank, and distributor) and you have spark and fuel, your engine will run. Try a compression test, and back up and re-test fuel and spark. Make sure the spark works with a HEI spark tester. (Coils can go bad and give a weak spark)
you coul remove the # 1 plug wire (1st on drivers side) and see if your getting a spark. It may need a new distributer cap and rotor.or it just may need new spark plugs. fair warnig I am not a mechanic but have had similar problems like this that I have had to fix myself.
