#5 cylinder has spark to the plug, 125lbs of compression with remaining cylinders all within 10lbs, #5 cylinder will not produce power at any speed.
Enriching fuel mixture creates approximate 10rpm gain, but still no power to #5 cylinder.
No vacuum leaks found.
What other additional diagnosis can I perform that will help in resolving my problem?
Thanks, chuck

Well check for pulse at the fuel injector, also try switching it with another injector and see if the problem moves with it.
