Return visit to replace the water flow sensor that was recommended by the manufacture. Upon completion I fired the boiler back up and found that the system still was not operating. I reached out to multiple representatives t the manufacture and every person I spoke to let me know that this boiler should be replaced due to age and lack of parts. After further diagnostics I did happen to find that the water pump seems to be struggling, in order to get the boiler up and operating again I believe we would need to start by replacing the water pump. Overall I highly recommend looking into having the whole system replaced due to cot of repairs needed and the fact that the manufacture does not make most parts for this boiler anymore.
