Starting problem hot/cold

[West Lagoons]

Have a KZN130 3.0 lt turbo diesel it is hard to start when cold also when hot have to crank it over for about 4-5 sec's before it will fire when hot but it will start straight away if I switch it off then start it within 2-3 sec's later.
the glow plug light goes out with in 1-2 sec's but if one waits the click can be heard at the end of the heating time (about 10 sec's).
Any ideas please

a new one. I also never start mine from cold without the "click" on a morning, after that throughout the day it fires as I turn the key. H

Try glowing up the heaters once or twice more than normal n see how it goes in the morning ..
Try parking face down hill overnight If ya think the Fuel primer maybe suspect n see how it starts in the morning !!
Good Luck
