Glad to hear you got it going!

The glow plugs are basically controlled by a relay which uses the resistance of the glow plugs as part of its operation. If the glow plugs are bad, that could cause the function and therefore the dash light indicator indicator problems you are seeing. Of course, it could just be a bad relay too... (as for your next question, I am not sure where it is located on your car)

\'87 Mer-B 300D (220,000 miles) (sold)
\'93 Mer-B 300D (173,000 miles) (sold)
\'87 Porsche 928 (101,000 miles)
\'98 Dodge Ram quad-cab (250,000 miles)
\'2001 CLK430 Cabrio (50,000 miles)

Past cars: 1969 mercedes 250, 1981 300D, 1972 220D

Rory - Yikes! No ether please

Rory:
  • Our diesels are designed for combustion in the pre chamber, not the cylinder.
    Ether also strips any lubricity you get fom diesel fuel.
    Ether does not have the timing control you get with the injection pump. Detonation before the valves are completely closed can push a valve open (interference engine).
Although use of starting fluids has been done time and again, your rolling dice.

Let's get that problem worked out, no bypassed. Start with a resistance reading across each glow plug, with the glow plug harness unplugged from the relay (just follow the wires from the plugs back to a connector on a black box).

Sincerely,
Scott

if it is not a fuel flow problem it is very good.
