The OBD reader indicates half the cylinders are dead on one side of the engine. Use an HEI spark detector (inexpensive) and check each spark wire end for fire. If the test indicates you are getting spark, then test the injectors using a noid light to ensure they are firing. You can also remove the injectors and check each one with ah ohm meter. If you are still good to go, get a compression gauge and check each cylinder on the affected side. You need air, spark, fuel, and compression for the cylinder to fire.
