Check the voltage at the glowplugs, should have a good 12 volts when the glowplug light is on. If the voltage is good, then I reckon your glowplugs are shot. If the voltage is low then look for bad connections and check the glowplug relay.
You can try cycling the glowplug light by turning the ignition on and off 3 or so time and see if that helps.

Yes, worth checking the leak off pipes etc. Also how much fuel have you got in the tank?

fuel just under half a tank will give the cycling tip a go now then off to work until tonight

thanks

Fill the tank, that will eliminate some of the possible fueling problems

Do a current check on your in tank pump, there's a thread on how to do it. I think the pump should draw about 4 amps if it's working.

thanks i took my tank off last week and removed the pump and checked it it was fine the plastic tank had no sediment or sand in it either this is frustrating to thanks for your help though it keeps me in ideas

You might need to buy/rent a syncmate , you plug it into your odbc port look at the lights blink and as if by magic it will start.
