Glow plug timing on 123's |
Even the old W114/115 220D and 240D with the knob you pulled out of the dash kept the glow plugs energized during the starter operation - on those cars the "salt shaker" on the dash was de-energized during starting but the rest of the glow plugs stayed "on" until you let go of the knob.
If the glow plugs were shut off, and the car didn't start on the first compression stroke, it wouldn't start from cold iron at all. Cold air, cold steel, cold Diesel fuel = snuffed out glow plugs if they are shut off. The fuel sprays right at them.
