I doubt if unplugging the Fuel Pump relay would have any affect on causing the Fuel Distributor to start leaking.

As far as the O ring you mentioned previously, I guess you are referring to the Control Plunger Seal in the Fuel Distributor.

Sorry-at the moment i have the fuel relay unplugged to narrow the scope-the fuel relay unplugged did not cause any leakage. From the info I am getting, the leaking fuel distributor will not be an issue if I am spraying ether and thus omiting fuel delivery from the tank. There is no leakage with the fuel relay unplugged-makes sense.

What i find perplexing is that I had the car fire nicely on ether once, plugged the fuel relay back in and it ran fantastically well apart from wanting to stall at low RPM-this was several days ago. Will check those two hoses more. One side had alot more movement than another-the one on the right. Thanks SLKred for the download!

Guys-I go the car to run. I first installed new plugs and went back to my trusty can of ether with fuel relay unplugged and it fired momentarily until it exhausted the ether. When i went to plug in the fuel relay, the car would not start so I unplugged the fuel relay again and sprayed the ether and it ran again momentarily. Back with the fuel relay and almost starts after jiggling the two hoses at the ICV. I went in the house and recall advice given by as shop owner in Florida that advised to disconnect the EHA plug to omit all electric inputs/sensors with a no-start. Went out unplugged the EHA and bang it started right up! The car idles rough and to be honest I am not sure exactly why the car started-new plugs or vac leak at the two hoses at the ICV. Will of course investigate further. Also, I had a trouble code for the 02 sensor so my CEL came back on but for now i happy to get the car started!! Thanks to all except dh jenkins-joking!!

To anyone with a no-start, I would suggest keeping in mind the basics of getting a motor to fire. I am totally new to this but it certainly seemed to work for me. I was more or less told that these cars are so complex that a novice should not even try but from what i can suss out, a motor is a motor especially if one omits the sensors which on this car can be done by disconnecting the EHA. The car will be harder to start cold but I have had plenty of experience running the vehicle with a dud OVP and in my experience, the car will still fire but may not stay running until the motor warms up. Thats completely different from a situation where there was no hint the motor would fire which was my predicament. I went one step further and disconnected my fuel relay and used ether which limits the scope even further. The other advice I recvd was to be careful with spraying ether as it can crack a piston. There was a funny story by one of the moderators of a guy who sprayed the entire can then punctured a hole in the can to get the last drop only to damage the motor. Others kindly advised checking the vehicle for air leaks esp at the ICV and plan to replace my hoses as they are hard and very likely played a role which I can expand on later. Thanks to everyone who helped!!
