freelander injector issue

Hi, just bought my first Freelander 03 TD4 Kalahari so new to the site, it was bought with a diagnosed fault being 2 injectors needing replacement, pressure tested all 4 and replaced the 2 faulty ones, started up straight away no problem, ran it for 1 1/2 hrs then drove it around for 2 days 30 odd miles no problem jumped in this morning to find it wouldn`t start at all,starter turns over,plenty of battery life, can hear the external fuel pump working but no fire up, any ideas or something sounding familiar? i have limited knowledge in the engine department so would appreciate a step by step if possible, its going to a garage Wednesday if i can`t sort it, but would still like to know what might be going on. thank you in advance for your thoughts and time.
