hi there im new here. i have a 84 550SEL that i am wanting to start to restore. its been sitting for about 7 years now. i am having a hard time getting it to even run. i checked and the fuel pump had rusted so i replaced that. looked like it was getting enough voltage, its cranking over with tons of spark but still no luck.. tomorrow i will check and redo the head gaskets as they look like they are done.. anyone think of anything else? i put fresh gas in, oil change etc.... what are the common problems with these cars? its got 101 xxx kms on it... where can i to find more info about this car? its a v8 gasoline, auto....i am also needing some interior trim peices, front head lights, signal, bumper etc etc

thanks
