I did check the oil level and it was within the acceptable range and did not smell of diesel. I am wondering if you are right about the coolant though. I may be seeing two unrelated things here. Yes the the pump is capped, lines removed, all injectors out. The clean diesel on the floor may be directly from the pump and the fluid coming out of the injector hole is something else perhaps coolant. With that said, how did any liquid other than oil find its way into the cylinder? Remember that this was the best cylinder of all at 300 psi. Even if the pump is leaking into the engine how would it make its way in to cylinder #1? Is it possible that the head gasket has failed? If so, is it possible to have failed across all 4 cylinder? Perhaps my next step is to perform a leak down test to see were the cylinder is compromised. I'm not sure which type of injector I have. How do you tell? Was my precautionary attempts to cap the injector pump a mistake?
