have you checked the copper strip/bridge.thats in the black box on your lefthand side bulkhead(as you look at it)its hidden behind all the wires..

most odd looking at the wiring diagram it can only be a fuse or relay

have you checked the temp sensor , if you disconnect the the wire to the temp sensor turn the ignition on the light should come on for 20 -30 secs in which case your temp sensor is u/s if it doesn't come on probably the relay.

would the temp sensor stop voltage getting to the gp bus? also the relay is new....stummped!

yes as it is basically a switch, so when the engine is cold it lets the relay activate the glow plugs and when hot not, so if its u/s no power to glow plugs,
it might also be worth checking that you have a good earth on pin 85 of the relay
