Not sure about your 91 but the older 917s had a fusible link in the GP relay on the left inside fender which was often the culprit if sudden no-start. If yours has a similar fuse, don't just inspect visually but loosen the screws to make sure it's really one piece. The one in my 82 300SD was cracked in two but you couldn't tell by looking with it installed. When I loosened one screw half of the fuse fell out.

Howdy -- My 91 300D needed new GPs in 2006 at around 100K Miles. This week I noticed it wasn't starting as crisply as normal and tonight my wife tried to come home and it would not start. As luck would have it I had planned to replace the GPs in the morning. Oops! Just one day too late! Anyway, she a RN at the local VA hospital and we called a tow company to get a jump - hopefully she'll be heading home shortly. Yep, we are waiting for the tow truck as I speak. Of course, I'm at home in bed and she's in a cold car during a cold rain after working 2 - 8 hour shifts. She's not real happy at the moment. So, I figure if I had seen the GP failure coming I could have avoided al of this unpleasantness. What's the consensus? Can we say they have a 100,000 mile lifespan? When I was looking at the GP technology I found some new GPs that are said to "heat up in 4 sec" - I guess it's possible since the new diesels don't require a GP warm-up period. At least that's what I've heard and read.
