HI everyone,

 

I would just like to put my thoughts down and see if any one agrees:

Before christmas I had just joined the motorway and was getting up to speed, Car lost power regained power for a split second the cut out. It will not restart.

 

I got recovered home and this is the first weekend i had a chance to look at it. I had heard stories that would most likly be snapped belt or chain but i suspect fuel pump. Here is ths steps i have done to come to that conclusion

 

1 removed cambelt top cover put a dab of paint on it - it rotates

2 Forscan shows no errors related to timing

3 Forscan show no pressure in fuel rail

4. My next though thought was chain, but on the off chance i squirted some easy start in the intake and for a split second it fired. Now i beleive the cam chaft runs the exhaust cam and the chain drives the intake. If that is the case then the chain is fine, and the fact it fired up to me  says its getting no fuel.

Forscan also showed compression in cylinders

So do you agree fuel pump?

2010 2.0TDCI WA6 Engine (140) smax 145k

 

Does it have dpf, if that is blocked it wont start.

How can Forscan detect compression?

Can you see diesel in the low pressure line near the filter?  I think there's a clear section of pipe on this engine.  If yes, remove the hard line from the fuel pump, place it into a bottle, and crank the engine over to see if any fuel comes through.  If not, either the pump is knackered or it's lost drive from the camshaft for some reason.

the fuel pump is run off the (exhaust?) camshaft on a keyway

sometimes said keyway can snap and thus the fuel pump does not turn
