Ok, I've got a 1981 300TD wagon that won't start. One of the things that is suspect is when the ignition is turned on, the glowplug light in the dash is only on for a second - so the plugs never get up to temperature. My guess is that its the relay? any other suggestions?

Is it cold where you live? If you have a few glow plugs turning on, you should eventually be able to start it.

If you have a multimeter you can check them in few minutes, if you find that more then 2 are suspect, its a good idea to just replace them all, Autohaus.com always has them at a reasonable price.

the glowplugs are not turning on. the light in the dash turns on for a split second and then goes out, so they are never getting hot... is that the relay, or does that mean there are bad glow plugs. the thing won't start...
