I know you've changed the glow plugs, but have you checked they're receiving power and for how long?

As above, but easy start sprays are very detrimental to diesel engines so the fault needs to be fixed.
If you have a huge mileage on the car, consider having a compression test done. Nissan / Renault have altered the service interval frequently on these dci engines - from 18k down to 12k. personally I change the oil and filter at 10k.
