No Spark 1990 buick regal Sign In

I have a 1990 buick regal limited 3.1L V6. 194,000 miles
i just replaced my starter and head gaskets, i had to dissassemble the engine to do so and when i put it back together it no longer gets a spark from my plugs. i pulled the spark plug out and tested it to verify there is no spark.

i hear the injectors engaging when i turn the key on, but im not sure if they are pulsing correctly because i dont know how to test them, this is my first car and i dont have any prior experience.

You need to use a noid light to test for pulse and a 12v test light to test for power supply.
