Hi guys - new here, but long time reader - great board.
To cut a long story short, my 03 110 Td5 has intermittent starting problems - it will catch 1st turn most times, but occasionally is a real dog to start - it will turn over fine, but will only catch after a few minutes of continous turning, and only then reluctantly.
When it's running, it runs fine - very sweet.
Never managed to isolate the starting problem to hot or cold, damp or dry - seems to be no pattern.
I recently had an issue where it just cut out on me (never happened before) on the M25 - the fuel was low (but the light was not on) - it would bump start fine, then cut out again after a while - this happened again and again until I filled up the tank, it was fine all the way home then.
As a result of that, I fitted a new fuel pump, + new diesel filter, and cleaned out the air bleed valve (soaked in petrol for 3 days before refitting, I didn't poke a hole in it) - it started fine, every time, then when I took it for a run - turned it off, did some shopping and came back - it refused to start.
Called out the yellow taxi service - he wasn't amused to find a Td5 - for some reason he reckons they mess up his roadside fix rate figures ;-) he squirted in some carb cleaner and it started (reluctantly, but started!) straight up. (The diesel tank was half full.)
So, ordered and changed the crank position sensor - I've already done the injector loom, I just had a trace of oil in the red plug - but refused to start until I gave the battery a bit of a boost with the starting charger, so no difference.
Any ideas as to what to try next?
This thread https://www.landyzone.co.uk/land-rover/td5-fuel-pressure-problem.161412/ has some good info in it, but I'm at a loss.
Ordered a fuel pressure tester, a new air bleed valve & some injector seals - the seals look like quite a big job, anyone in the Surrey/Sussex area can hire me a slide hammer?
Any ideas? totally lost - oh, I've got a big battery on its way, just in case its an electrical issue - if the ecu is being starved when it's trying to start - the battery on it is probably a bit small.
In summary - runs fine mostly, but intermittently hard to start. Had it 2 years, always had this problem, but now seems to be getting worse.
Will start straight away if bumped, or reluctantly if the battery is given a boost or ether added, otherwise not at all.
Changed the injector loom, fitted new fuel pump (makes same noise as before), new crank sensor (no difference).
The plan atm is to fit a new air bleed valve & pressure test - a bit reluctant to change the injector seals given the size of the job and the fact there is no sign of diesel in the oil.
TIA guys, much appreciated.
