hi guys , quick question if any 1 can shed any light for me would be good


so i not long bought a nice 06 classic animal 4d46 2.5tdi that chucked a rod through the block . i thought no worries i got a spare block

so it looks like the block i have (taken from a 2002 animal ) is an old style block that had a protruding valve head fitted , due to it having pistons with sort of clover leaf shapes to the dimple on the top of them , so looking online to see if a flush valve head would work on it it seemed to yes was the answer but with a very small amount of compression loss . i can live with that i thought just for a couple of months till i can get a block and get it rebuilt , so put it all togeather and started her up , took fooking ages to start and runs as lumpy as fook and smokes bad . now wont start at all .

i did find that the EML light bulb had been removed aswell so i have put that back in .

is this due to wrong head ? or anouther problem .

i also see i have hardly any diesel squirting out of fuel rail when i crack it off to bleed it . i get a tiny dribble of fuel , could this be injector pump .


bit of a bugger really as i sold my nice rebuilt top to bottom 52 plate animal so i could get this newer 1 (cos it looks better all in black ) so i now have no truck till i can get this 1 running . does any 1 have a fuel pump they would sell if it turns out to be this .

any help would be great guys

thanks you

how is the timming? and have you checked the pump pre lift

timing is good spot on in fact . not looked at prelift as yet . tad worried about the lack of fuel being well not squirted out the injetors when i have the rail lose for bleeding .

Take it pump timing is spot on too? Do you get an engine light come on ? How about running it out a fresh can if diesel?

id try by passing the tank and filter and running from a gallon can

once firm ,the primer shouldn't go soft unless you've got air getting in the system somewhere

check stack pipes on fuel tank as they corrode and air could be getting in

what he said! thats why run it from a can then u kno it is only a couple of things if it runs well from the can

well done the can trick . still no joy . getting feck all fuel through the pump to injectors i will assume its the pump that is at fault? i even cracked off 1 of the lines on back of pump . barley gets the pipe wet with the ammount of fuel dribbling out

Silly question you have connected the electrical connection for the pump , and all the pipes are done right? ( don't want to make it sound like i'm treating you like an idiot , its just easy to forget the simple things sometimes!

Before writing off the injecter pump entirely, check the fuel stop solenoid on top/back of the pump - it should be making a buzzing sound when the ignition is switched on. If not it is knackered, or you have faulty wiring. Next you want to get hold of a multimeter and check all the resistances across the fuel pump electrical connecters, as detailed in https://arbtalk.co.uk/applications/core/...t.php?id=232346, page 62.

will take a look tomorrow between rain showers , and report back

when i got it to start the other day it took about half a can of break cleaner , but she did run , lumpy as fook but ran , tons of smoke and would not rev past 3.5k . spluttered like fook while reving it aswell .

Here's a vid of one with a faulty crank sensor - it does sound a bit like your problem, but hard to tell really.

Stop solenoid should be making a very audible buzzing when ignition is on.

Ive been running mine without plunger and spring in the stop solenoid for 2k to date. After a fuel problem.04 k74 . No problems since but assuming i would have try stall it if it would not shut down.

so popped out to the ol girl to try removing the fuel stop solenoid , took it out removed the plunger and spring screwed the big bit back on and cracked off injector pipe , still no fuel to injectors even with the stop removed .

went to undo it to put plunger and spring back in and had some hissing then a good squirt of fuel came out , done it back up still with 1 lose injector , yet still no fuel to them . tried undoing 1 at a time nothing , thought bugger it undid the fuel pipes from back of pump , not a dribble cumming out .

looking more and more like a fubared pump isn't it ?

any thing else i need try before i take to plunge and try to find a used pump .

Have you checked to see if its blocked up with owt my problems started after veg use. Check the metal pipe front /top. Ran mine on petrol/ diesel mix for a few tank fulls after removing and cleaning fuel tank etc.

may try blowing it through with airline , see what that does .. looks to be getting fuel up to the stop solenoid point but no further . poss blocked in rear of pump where the fuel pipes to injectors connect ?

is this a fbw truck?
