the six million dollar question is after refitting the engine gearbox and fuel tank on my 04 disco it wont start it turns over no problem but the fuel pump was noisy for a few mins so i think it may be fuel related however whilst the engine was out the fuel block was renewed so maybe this needs bleeding. if i pull the fuel line off at the cooler will it spray diesel thus eliminating fuel pump or trapped fuel line ? i was under the understanding thease are self bleeding but could i be wrong sorry if boring thread but im a bit stumped
Hi to all, first post although I've been reading the forum for a few months.
I recently changed the gearbox on my 03 TD5 130 and after putting it all back together it like yours would turn over but only start when it felt like it.
plugged it into a diagnostics computer and no problems, so i changed the crankcase position sensor - thought i might of knocked it changing the box, no change.
next I changed the airflow sensor, still no change.
then I read on the interweb about starter motor problems on the TD5 sometimes causing starting problems, having already done nearly £100 on the other 2 sensors I found a starter motor refurb kit on fleebay for about £10 plus a couple of quid postage,
so ordered 1 and having fitted it after having to drill and retap 2 out of the 3 screws holding the end cap on the starter put it all back together and back to normal starts first time everytime.
the old plunger and contacts were badly arc damaged so i guess when I undone the bolt holding the positive lead it must of moved creating the starting problem.
may be worth having a look at yours.

I'm not special I'm limited edition
did you purge the fuel lines and injectors?
have purged it now ran really lumpy for 5 secs so i think that it could be a problem with the fuel return line as the union snapped when i removed tank got a second hand union and used rubber fuel line to repair so it could be that the fuel line is loosing pressure as the rubber expands whilst under pressure any ideas
