Check to see if the fuses are intact.
This may have been your initial problem.
You may have created a problem by removing and banging on your EHA.
Better to leave things alone if you do not know how they work and how much it will cost to replace it.
EHA is not an inexpensive part and is a critical element in the CIS-E system.

You are so right - it is better to leave things alone if they work especially if one doesn't know what their doing. - BUT I again didn't follow this advise and I removed and re-soldered the connections in the OVP - HOWEVER this time with good results. See the update to my original posting.
