If you did not unplug the glow plug relay, then you were reading all glow plugs connected together and would not be able isolate which one is bad (if one or more is bad). You said you are getting 2 to 4 ohms? That's a strange reading with glow relay connected. I would have expected around 1 ohm if at least one glow plug is good and infinity (open circuit) if they were all burned out.. Glow pugs must not have power to them when taking resistance measurements.
