Late this evening, around 10pm I hopped in my trusty old 1979 300D, and without thinking I turned the key to start without waiting for the glowplug lite.
The car cranked and cranked but did not start. Realizing I may not have waited for the light, I sat in the car for 10 minutes, then turned the key, no lite. Then 20 minutes, then 30 minutes, and still no lite.
I'm Going back to the car in the early morning, hoping it works as intended.The glowplug lite has always operated, and through the day, it gave no indication of failure.
Is this a normal condition when you inadvertantly try to start without waiting for the lite?
Any thoughts or suggestions would be appreciated.

Hi DD.

A sudden failure like that is most
likely the fuse in the glow plug
relay.
Or the relay itself but check the
fuse first.
The fuse is a metal strip
mounted in between two screws.
It might look good but sometimes
it has fine hairline cracks that
are impossible to see.
They are cheap, even at the stealership.

The relay is located on the fire
wall next to the brake booster.
It is a black plastic box.

if u "popped" one of the glowplugs(nothing to do with ur starting, purely coincedential) then all of them will be out of commission. theyre set up like the old christmas lights we like to search through so much, looking for the bad bulb. if one's out, u have no circuit, thus no glowing.
