So here's what occurd while changing the oil in my 1991 240. While I was getting the oil wrench attached to the back of the oil filter it slipped and touched the back of the altenator. A small spark and it feel down below the car. Of course I felt stupid for not disconnecting the battery first. But now when the car has sat overnight it will not fire until I turn off the key and then try for a restart. Then it will fire right up. Have I shorted out some part of the fuel system? I will double ck the fuse's but could I have done something to the pre pump?
Relay? Other?

you're on your own. never heard of it happening. and i've seen sparks from the alt, just like you. good luck, chuck.

Well it must have been a fluke because it happened once and after that it starts normal. No fuse blew and I'm real glad I hear that fuel pump singing in the tank with key on. I'm going to never forget to disconnect the battery at the oil change again.
