i very rarely need the heater plugs even in this weather!if i do use them the light stays on for about 10 secs. are you sure you dont have any airleaks causing bad starting.i would look at the return pipes on the injectors to make sure as these can rub on the engine cover and become holed very easily.

Return pipes etc all in good order,when I said engine was sluggish on starting I meant that it takes it a few turn overs before it starts, but when the glow plug timer is working ok it starts right away

Having exactly the same symptoms, I have changed pre heater relay, still the same. I am sure there is another relay in passenger footwell, you can here it click. That is going to be my next port of call.

Have you ever cleaned the earth strap connections to the chassis?
If the engine spins fast enough you shouldn't need to worry about glow plugs, it should start even if they don't work.
