Sorry for the delay,to everyone who has been kind enough to be helping me, I got called out of town for work. Back now.

mak: Thank you - I know how to clean the pins, but how does one clean the sockets? I don't have anything small enough to get in those little holes!

S-Class Guru: Thank you - When I turn the key on, I can hear the fuel pump hiss. When I turn the key on for a few seconds, then off, then on for a few seconds, then off, three times - the car starts faster but still not right away.

What does turning that knob on top of the MAS relay do?
