glow plug light wont come on

[Pat ingram]

I recently washd the van and saw some white scale over the coolant lid, i took this off to clean and see if there was a leak, there wasnt and put it back on, today i,ve gone to start it, but the plugs arent getting heated up, the plug dash light isnt comeing on and more bizzarely the temperature needle flicks back and forth then stops. i,ve check the leads and cant see anything loose, theres plenty of juice in the battery, theres plenty of coolant,
thanks for any help.

Is it starting? in my 307 when I turn the ignition on my temp needle always goes to the top then back down, as for glow plug lights I never see them even when its really cold, but my car starts fine and has no prolems.
