intermittant starting problem

hi 02 freelander td4 every now and then with no apparent reason the car will not start just cranks over, does not matter if hot or cold if left for a couple of hours will start and be fine might last untill turned off again or might go a few days, the eml light is not on and i have had the codes checked with no codes stored.

Iv found a fault in the past due to a sticking low pressure diesel pump(pre supply pump) . Depending on the age I think it's under the nsr wheel arch.
next time it doesn't start it might be worth either locating the pump and giving it a knock, u should be able to hear the pump running when u put the ignition on although it will be quiet.
Or checking if u have low pressure fuel to ur engine when the car won't start??

Hope this may be of help

I agree with previous reply, Mine did same as well as holding back at top end of revs. when pump was tested it had good pressure. A new LP pump cured it.
