Hi Ray and All !

I had a question on a 1997 E420. The Car had gotten wet via the sunroof. I disconnected the battery for days and the car will not turn over and start. It almost sounds like its starving for fuel. When turning the key to the on position, I hear something under the engine cover start to almost whine and click, the noise continues and doesn't stop. I finally left it on for about 5 min, and then I heard it go off. All the electronics in the car do work, Lights, Horn etc.. I checked all of the fuses with a tester and everything seems to be fine. Do you think the car not starting is related to that "whining Noise ? Is that the Fuel Pump ? What may I check from this point.

Thank you
