it wont be heater plugs more likely drawing in air usual places are steel elbows on the pipes in the sender unit under cover in boot floor or lift pump or sedimenter on inside of chassis o/s rear wheel area,leaking leak off pipes can cause poor staring too

What if the starter has a problem as the current draw is to high while cranking? ... try to bump start it and if it starts well replace the starter

You should have mentioned the exact type cos if it's the one with the DDS then it can be some ECU problem too
Depending on age, It could be EDC rather than DDS ( I'm guessing this is what you meant - deffo not having a go at you
)IIRC, EDC was from chassis "MA" ( auto only ), and DDS was later, possibly "VA" .... (SWMBO's D1 manual is DDS, my auto was EDC
)OP, don't quote me on the above, look it up online, but we still need to know whether it is EDC or not
check the simple stuff first - air in the fuel system is quite normal for a vehicle of this age, and all the Bosch FIP's are pretty tolerant of it, to a point ...... it does sound as though you might be beyond this point

NO. i mentioned the DDS cos that's the most complicated version of EDC cos the injection pump is electronically managed by the engine ECU based on a security signal from the DDS immobiliser and i've seen strange missbehaviours of the DDS on a friend's 300tdi which had such kind of crank no start issues
