Hello, this is my first Mercedes so I know nothing about these cars. It is an '89 300TE. Tonight it was very hard to start. It took a number of tries, finally started. It would start, then quickly die. I made it home, now its doing the same thing. Any ideas. Where is the fuel pump relay? Is it easy to check? Is the fuel pump in the tank? Is it easy to check? Any help would be great! I LOVE THIS CAR! Thanks, Mike
