The bulb should go soft once the engine is running. You are right that air getting in is a known problem, the other thing to do is check the microfilter, if you search for microfilter on here it may point you in the right direction.

 

If it has the YD25DDTi engine there is no micro filter, these were on the TD25 engine.

 

Jet wash? Might be water in the fuel, or in the electrics perhaps?

 

i belive its the YD25 engine not sure on the DDTI bit
tryed a search on site for micro filter and cant find its location i have noticed a small filter on top of the tank
if water in the system thought the filter should catch it and after re fitting with fresh fuel would have thought it would have briefly started even to just run on whats in filter
baffling me as i did 9 mile after the jet was before it lost power

 

No micro filter then.
A few older D22's have suffered with rotted metal fuel pipes were it exits the tank, if yours was covered in crud cleaning it off may have let air into a porous pipe?
When I change a fuel filter I always try to purge the air from the very last connection on the fuel pump, loosen this off and work the primer pump until bubble free fuel comes from the loose joint, then tighten up and start the engine.
These engine do not tolerate any air whatsoever in the system!

 

right just having a quick look at sorting the truck as not had the time or weather really (i only have basic diy mechanical skills) and my motto is if its broke you can't brake it so have a go
i have taken feed pipe to filter of to try and narrow down the search and found on cranking it over there is no fuel coming out of the feed pipe so im thinking its from tank to filter am i right or would it not feed fuel on cranking over next job to inspect pipes on tank and to fuel filter

 

if its the same as the D40, the fuel is sucked from the tank. theres no pump in the tank, so you wont get fuel from the feed when cranking, only suction from the engine side.

 

:awesomeworkok thought there was as got a fuse under dash and there is wires going to top of tank.
im bak to square one again then still looking

 

The D40 has no pump. really need someone to confirm since I'm only suggesting its the same

 

""WONT START part2""

right
i have been outside today trying to get the truck to start and still no joy ,i have now replaced fuel filter and cracked the injectors and fuel is getting through to them as i could not find any faults on any pipes.
so im still scratching my head as to why it wont fire up turns over fine any ideas where i should try next

Did you get the truck sorted?

 

easy way to eliminate the pipework from the tank is use a small can with diesel and pipes straight to the filter.

With a diesel its pretty straight forward you have fuel you have compression you have air is all you need however on modern diesels there are a couple of other little gizmos to look at, not 100% sure on the D22 but the older nissans had a solenoid on the fuel pump that cut the fuel when you shut down if this is faulty it wont start, if the immobiliser is set to trigger or disable the same solenoid same result, it used to be the go to option to immobilise diesels a few years back, if you have electronic activated injectors then they can also disable the relay for that or if its faulty then thats another thing to look at.

Am really not too familier with the D22 but if they have a MAF in the air intake it may be dirty, one final thing the SCV may be faulty as well but honestly am not even 100% sure D22s have them.

 

This is the correct diagram.

 

I had this on my 22, its coughed and spluttered and ran for a little while then decided it would turn over and not fire up, had RAC out and hey confirmed it was the fuel pump, cracking the injectors showed fuel from pump but not enough to run, had to replace pump £1400 I think or something like that from Nissan I got one rebuilt from these guys https://www.pfjones.co.uk/nissan-na...k/nissan-navara-d22-2.5-td-reconditioned-bosch-diesel-fuel-pump-0470504033.html pain to remove the old one but new one fitted and so far she is going strong

 

no not yet not had chance to get back to it and reading the comments about fuel pump im afraid if it turns out to be that i will be cutting my loses and scrapping the truck as don't need that extra expence

 

blonde moment here

can anyone tell me where i can find the egr done a search on you tube and they all look different engines to mine and all in different locations

all the posibly locations.no 4 are the newest ones and no 1 the oldest

 

thanks very much maggos :bowdown1 i have had pipe of from one side filled with a lot of soot and wasn't sure about the other bit will get on it tomorrow if weather permits its photo 1 for me

 

towed it down the road and got it to start its ticking over dead lumpy and wont rev above 1000 revs turn it of and it wont start again so im at a loss and seriously thinking about letting it go

 

Did you get it sorted??

I have the same problem
