Post 1979 450SL

My '79 450SL fuel pump relay went out & I replaced it, now my car doesn't want to start & stay running. Could the safety switch also be bad? It seems that the fuel pump only runs when the starter is actuated or the engine is running. I need a diagram or picture showing me the actual physical location of the safety switch sensor plate so that I can preform a check on it.:
