In a simple diesel such as the 1.9, you only need heat, air and fuel for it to run properly.
HEAT is generated by engine compression with some initial help from the glow plugs.
Problems can be- Not enough engine cranking speed to generate heat / Not enough compression-worn rings or valves not seating properly incorrect cam timing so compression escapes, or glowplug problems.
AIR- Blocked air inlet, filter or exhaust.
FUEL- Not being injected at correct time (timing) Not atomising correctly, poor spray pattern / low injector pressure (hosing) or no fuel (air in system) faulty stop solonoid. Faulty injector pump
A few of the above can be eliminated by seeing if it runs normally once started leaving you to work through the rest. Various bits of the above can be tested quite simply, eg a compression test will reveal low compression which will prove or disprove the valve clearances before you strip everything out.
If compression OK then valve timing, valve clearance and worn rings can be ticked off the list
