126 wont start '85 380se

[barndoor]

Today I started my '85 380se and moved it about 2 feet down the driveway.(It was in the way).It was making its "bearing going out noise" ,which I think is the water pump bearing,the noise sometimes occurs on cold start up,and lasts for about 3 minutes.and then wont happen all day?But that's not my main problem today,today the car wouldn't start up again after the moving it 2 feet about an hour earlier.
I went directly to this site,
It sounded according to what I read on this site that it could be the "Fuel Pump Relay"
The car started right up when I hesitatingly sprayed "starting fluid" into the intake.
I pulled the "Fuel Pump Relay" and bridged jacks 7 and 8.At that time the fuel pump made noise which it was not doing before.
The car would not start due to a now LOW battery.
I am ordering the new Fuel Pump relay on monday,I would just like to verify that ,that is what the problem is?
p.s. my fuel pump relay looks like it has been apart and resealed with silicone? hmmmmmmmmmmmmmmmmmmmmmmmm???
any help greatly appreciated ,by the way this is the best auto enthusiast site I have ever seen!
and as others have said "is ADDICTING!!!!!

I had a similar problem with my W126 280 SE 83', it would be impossible to start when warm and run rough. It ended up being the fuel accumulator. I don't know if your model has it but its worth checking out. Its a small cylinder case in the fuel line near the rear Diff and is for keeping pressure in the fuel line.
Check it out as its a cheap repair.

Check the fuel filter. the previous owner neglected to do this on my 380SE, when I changed it, it made a great difference in starting/idling. could be contributing to your problem.
