The dash light for my glow plugs on my 300SD began blinking today and it was difficult to start. Could this mean there is a fuse blown; or, might this indicate a glow plug totally burned out. Rev Wallace Schulz

You have a bad glow plug. The GP light flashes slowly when one is out, faster if two are out, and usually doesn't come on at all if three or more are out.

Won't start by then, either.

I replace them all at the same time, others on the list will tell you to find the bad one and replace it only. Do as you please.
