Fuse panel relay help
I have a 2002 C230 coupe, and I was trying to figure out how to check the fuse for my cigarette lighter. My wife was taking a trip this morning and needed the GPS unit hooked up. Instead of fixing it (through the forum I found out is was under the hood #47 15 amp, and the fuse was fine, thus we need to purchse a new cigarette lighter), I also managed to totally screw up the car. When originally looking for the fuse panel chart, I went to the panel in the trunk and started pulling a few relays and fuses. It ran fine minutes before this. When I went to start the car, it would not crank easily and shows all the signs (as I have read from this forum and others) of a fuel pump relay problem. It can get started by pumping a little gas, has a difficult time idleing, and accelerated with some noticeable lags.
I am quite sure this has to do with my messing around with the relays and fuses. I checked to make sure everything was tight and back in place. I have a fuse panel chart but it doesn't say which relay works with what (only fuses). I am a total novice at all of this, so I have some questions:
1) Does anyone have a diagram of the relays of a C230? Or can anyone tell me (ABCDEF?) which one it is? There's a slight chance I put the relay back in the wrong slot (but I have tried all of the options)
2) Does my problem sound like the fuel pump relay, or could I be missing something else?
3) What could I have done to mess it up? Should I clean it (if I can tell which relay it is), how do I clean it?
4) Is there some reset button (I read that some relays have this) that I just can't see?
I hope I'm not adding needlessly to the volume of threads; I tried to search several different ways for this for over two hours to no avail.
Any help would be greatly appreciated.
