220D Not Starting
I have a 220D that sat for several years, but previous owner said it ran last year after compression starting. I have no glow plug light before and after pencil type glow plug upgrade from mercedessource. Motor spins fast enough and acts like it wants to start. I can smell burnt fuel from the tailpipe, but it just won't catch. When the starter knob is pulled out to the glow position I do see the dash lights dim a little. I've found a couple of comments about W115 220d's not having a glow plug relay. What else can I check to verify function of the glow plugs? I've bled the fuel system and believe the fuel supply is adequate. Troubleshooting suggestions are appreciated.

New Glow Plug Manual Available
Hi Marc, I just released my new Advanced Glow Plug Testing and Repair Manual today! This will take you through the whole process of testing your 220D system. Go after the glow plug system first. If they are working properly then do a valve adjustment and compression test. CLICK HERE to order the glow plug manual
I appreciate the
I appreciate the suggestions. The glow system checked out fine, even in the absence of a functioning glow plug light. It was valve adjustment that turned out to be the difference. As I went through the process, I found that only three of eight valves were adjusted properly. Your valve adjustment wrenches are a joy to use and helped make this a pretty simple procedure. As soon as everything was adjusted properly and reassembled, the car fired right up!
Great news
That is another great success story. Good work! Thanks for sharing it with us. Kent
