fuel pressure was at 55psi where it is supposed to be. Not sure what you mean by compression I am not that car savy, and checked the spark from the prong to wire plug on all plugs and made sure the module under the distrib cap is good as well.
I also checked the fuel relay and that checked out fine and was working.
