Very welcome Ted, hopefully that is the culprit, I have the L36 also, it is a solid motor once things like lower intake manifold gaskets are replaced, if you still have the old original lower intake manifold gaskets that are nylon, then I highly recommend replacing them, and swapping out the EGR stovepipe with the one that come with the LIM Gasket kit.
It just dawned on me that you really do not need to remove the ICM/Coil Packs, and brackets above the water pump to remove the pump, mine were removed because I was doing the LIM Gaskets at the time.
I'll post a pic of the bracket I was referring to, if you did not remove it for any reason, then the ground I am thinking of would not be the cause of your troubles.
