could be either but if you take the hose off the inlet manifold that will allow enough air in there for it to tick over if it is the lower pipe that is blocked.

try and remove anything that can stop air flow into and out of the engine. but start with the easy stuff first.

so its had easy start.

my money is on either a timing or compression issue, I am leaning more towards compression.

its still worth trying the other things mentioned in the thread. check for smoke out of the oil filler, bubbles in the cooler header tank. not like bubbles in a bath, bubbles rising up when its being cranked or poss a min or so after give then chance to get through the pipework.
 
Intercooler hose clear just light oil round edges inside. Exhaust seems ok ive gone along the whole length of it tapping to make sure its hollow and giving it a shake. No cat on it so its a straight through pipe. Going to see if fuel comes through injector unions in a min with the solinoid unplugged and check if smoke is coming out of filler
 
cool I am interested to know the results, the exhaust being blocked is a long shot but not one to be overlooked. fingers crossed for the solenoid but it didn't do anything with easy start so I don't think its fuel related now. but still worth a shot. don't forget to check for bubbles in the header tank
 
so the engine is getting fuel and air and the exhaust is not blocked so it can breath. the only other things it needs are a suitable environment to combust (timing and compression) the timing appears to be ok as you can see movement under the rocker cover. if the timing belt had gone there would be no movement there is a small chance that the timing belt could have slipped a few teeth and the timing is now out but that's unlikely.

it is sounding very much like compression, could be head gasket or piston rings. I think the next step is a compression test.

Hi my Disco wont start its like it is not getting enough fuel through.
I have changed the fuel and air filter and also fitted a new fuel lift pump (Delphi) but it still wont start it has been parked at my brothers for 2 weeks now.
I also bypassed the sedimenter.
The injectors have all been checked and there all getting fuel through.
Any ideas??
Thanks in advance

how much fuel,, check the 2 pump banjos front should have big hole, rear small, if you leave front loose and pump lift pump fuel with no air should gush out ,
 
AA bled the system through the injectors yesterday. Any way to do a compression test myself? Or is it a garage job. Im pretty close to giving up and selling it i know they break for decent money but i havent the time to break it
 
you need a test kit to test it, you may be able to hire one?

I saw a bit of an old trick a while ago where you can get an idea if its the rings or not by puting a few drops of engine oil in each calendar. the theory behind it is if they have not completely gone the oil improves compression by very temporary sealing the gap but you need to be really careful how much oil you put in there! do you youtube search for wet compression test.

have you checked your water header? what dose that look like?
 
Normal as it hasnt moved anywhere. It needs a waterpump fitting anyway was booked not Sat just gone but Sat before but couldnt get it there as it wouldnt start the Weds before
 
see if you can hire a compression test kit. I think you can buy one for about £30 but then you have to wait for it to get to you.

it sounds like head gasket to me but I am no professional by any stretch of the imagination.
