I was driving to work this morning and as I was going down the slip
road to enter the Motorway the engine lost power, cut out and died
on me, had to be rescused by a big ape in a banana mobile, (A Steve
in a Yellow Cupra R) before getting dumped in a Costa Coffee car
park we had a quick look.
Car has oil.
Battery is 3 months old, connections and slam panel earth point is solid.
Alternator is 3 months old, wiring is solid.
Car Cranks, wont start.
Has compression.
Both belts replaced 2 years ago.
Coolant is as it should be.
Narrowed it down to either the Pump or the main BCU but any other
lines of investigation would be great, should the next test be to take
off the top boost hose and spray WD-40 in it to see if it will fire ?
Car is a 2004 (54) ROVER 25 2.0TD 106k on the clock.
My guess would be fuel pump. Mine went in similar circumstances, died on motorway slip, aa checked injectors and fuel was getting through, but obviuosly not enough.
Start with the injection pump belt (& check pump timing) - you might be lucky - not tremendously likely but I've had one fail. There's not much dismantling to get at it so it's an easy place to start.

Assuming the cambelts are ok then yes spray something combustable into the engine whilst someone is cranking it to see if it runs. If it does then its a no fuel problem and likely to be the pump I'm afraid. There are some checks you can do to see if it is fixable in the dirty diesel section.
Anything oily that burns will work fine to prove the point. If it fires then there is a fuel supply problem which points usually at the pump which lets face it isn't the most reliable bit of german engineering ever.
Well we investigated on Sunday evening, first thing we did was whip
off the fuel pump belt cover and we were treated to this.
So just thankful that this is all it was, hoping it will fire up once a new belt
is fited, the only issue is that this belt was fitted brand new along with the
timing belt less than 2 years ago, not sure if I should be worried or not ?
Because i'm cheap I repaired the belt but better judgement got me in the
end as I used steel staples not copper ones lol. :lol:
Ordered and new DAYCO belt, should be here tomorrow, we will check the
cambelt for premature ware when we fit it.
There have been several failures of fuel pump belts. I guess a bad batch. I think they were all dayco ones but not 100% sure on that. Cambelts seem to be unaffected thankfully.
My pump belt that failed after less than 2 months/under 1000 miles was an "Allmakes 4x4" belt - as was at least one other reported on here. It was supplied as part of a kit along with a Dayco cam belt (which did not give any bother).
Timing pin in the flywheel
Timing pin in the pump
Loosen then tensioner
Loosen the 4 bolts on the cam pulley
Fit belt
Tension belt FIRST
THEN tighten 4 cam pulley bolts
Remove timing pins and off you go.
Belt fitted, no joy, sprayed into the top hose and it spluttered to life
briefly, so it looks at the belt snapping has mullered the pump or the
pump is mullered and snapped the belt, either way the car is still not
working so we will take a fresh look on monday and check its all timed
up properly and check the cam belt is timed.
As a precaution does anyone have a pump for a Mk2 25 ?
Does anyone on here do pump repairs ?
Thanks for the help so far folks, keep it coming. :broon:
If you don't already know that the cam timing is correct then my bet is you've got the pump timing completely wrong - I would not have attempted to fit a replacement pump belt without knowing that the crankshaft was pinned in the right position & on the right revolution both by having the timing pin inserted & by looking at the timing marks on the (front) camshaft drive sprocket. Without doing this you can be attempting to set the pump timing with the camshaft 180 degrees out of position.
My mate who fitted all the new belts originally for me set it up but
we will check again after the weekend, were both working as we
were doing it in the rain and had flat batteries to contend with, not
ideal conditions.
Well thanks for all the pointless info you bunch of n00bs, jeez this forum
has really gone down hill, thanks for leaving me hanging with no help.
We did it all ourselves so no thanks to you lot, we re-stapled the old belt
with proper copper staples and pinned the pump with a ROYALS ciggy in
the a position that is wrong according to you lot and the 'Haynes Book of
Lies', it runs mint now, like a skeleton cracking one off in a biscuit tin while
in a tumble drier with a couple of bricks.
(As if you need a sarcasm warning after looking at all this lol)
Should see my Edam Head Gasket and Olive Oil Coolant !
