hi guys i tried everything with my 2.5t.d and looks like the injector pump is a goner i got one from the same year car second hand as new is to much its the exact same type will that just slot in without going on a computer or is it a costly job thanks guys advice welcome Richy :y :y :y
-
i would imagine its a straight swap over as i dont believe its fitted with the immobiliser system like some diesels do [transits i think], as youve got the pump anyway you may as well fit it & see what happens, never had to do one myself so dont know how difficult it is to do but good luck with it :y
-
thanks for that mate but the timing has to be done to i think

thanks for that mate but the timing has to be done to i think
hmmm, never thought of that :-/, & the haynes manual dont cover a diesel, dont suppose its a matter of lining up the old one in a set position then put the new one in the position the old one was at, perhaps a manual from other that use the same lump might be available[landrover td5 or the bmw etc] that could help, but im sure there is somebody on here thats in the know on these things & perhaps they will tell you how,,,,good luck :y
-
thanks mate il hang around a bit :y :y :y :y

you need couple of special tools to hold the timing chain in place for a start, or you strip off the timing cover and chains and do it that way, if the ecu had the same 10 digit code as yours then your ecu will driv e the pump o problem, but its very unusual for a pump to die completely, whats the symptoms of your old pump???

she takes forever to start when hot it gets to 70 mph and being an auto she kicks back a gear gains speed changes up and so on . i changed the in tank pump to start , no good bleed the whole thing changed the filters still no good so i think its the injector pump oh if i play with the peddle it will gain speed i got a injector pump cheap so il try that any ideas :'( :'(
-
is eml on?
-
Maybe you have two problems. I breaked around for ages with my liftpump before changing the leak off pipes (thanks OOF) They had looked fine but after changing the car started perfectly. The auto thing might be something different. ::)

if it starts and runs fine from cold dont see how it can be injector pump> sounds like air in system to me? if it changes down at 70 and revs higher then it isnt pump wondering if you have a dodgy autobox???
leak off pipes sound a fair bet.
for hot starting try pouring cold water over the ijector pump when its hot, if it starts fsirly easily then its fuel temp sender goosed in the pump this can be changed in situ :y
-
richy have you tried it with the airmass metre unpluged.going down a gear then up a gear is what i had to do to keep up speed when my airmass metre as fubered.
-
sorry it starves a 70 lowers speed then drops a gear i tried the water test the leak off pipes, could be how do i check them as for the mass airflow meter, could be. thanks guys richy
-
if you do have to change pump there is an imobilizer fitted on pump so will have to swap these over they are held in with a odd shape bolt but got it off with a small chisel on the last one i changed
-
u know its funny u say that the day before it started to run crap the battrey went dead and the alarm kicked in would that have anything todo with it running bad thanks guys . richy

This hot-starting problem is a 'pain in the proverbial' on 2.5TDs .....
Mine was exactly the same - after a new pump (1240 quid) and No4 Injector (300 quid).
In desperation, I fitted a brand-new correct-spec battery (65 quid) and 'right as rain' for the last year. Lads here then chipped it and now I've got a quick-starting flying-machine.
I'd certainly try the cold water test first, and change all of the leak-off pipes as a matter of course. Then, if the alternator output is okay, fit a new battery like me.
Much easier than changing the injection pump, and nothing to lose.
Gear-change problem, is, I reckon, a seperate issue here.
-
i think the gear change problem is due to it being starved of diesel cause when i feather the trottle it ok that wot makes me think injector pump i tried the water test and i put a nearly new battrey in it after the alarm killed the first one no difference help please :'( :'( :'( :'(
-
Two points here Rich:
1st - what's the amount of fuel in the tank when the hot-start problem occurs?
2nd - What's the output from the alternator?
-
when full i put a new in tank pump in her i dont know about the altonatior but the battrey is allways charged . richy
-
all ways full or empty mate
-
i pulled the MAF out this morning it made no difference so i took of the pipe leading to it . its got a lot of oil in it would that wreck the maf and make it run bad ???
