Hi all. Confession time first. I don't have a full fat, i have a sport but not many people on the sport forum with a 4.4 SDV8 so trying here. please help.

My sport has broken down. Seems like lack of fuel. One morning it struggled to start and cut out. tried again and fine. Drove in my Garage to change EGT sensor. After this it was a complete pig to start like no fuel.

Finally got it going and was perfect, starting idle, fast runs slow runs for around 50 miles. next day had a 90 mile drive all ok until 1/2 mile from our hotel and it just died. Flashed up low fuel rail pressure. would not restart. Cleared codes still wont start. AA were no help and can't get a specialist to come to my house to fix or recover.

Both times its struggle / not started its been jacked up at the front or on a hill front high. Diesel is 3/4 tank.

Fault code P0087-84

I've checked filter and all good. checked pump in tank and work. go through the prime process (ignition on 30 sec off then repeat 3 times) it then fires and dies

Sorry for the long message just pretty desperate. Any help or ideas would be great. seems like it just cut off like a switch turned of.

Fuel Injection pump? Whats the diesel pressure like at the injectors?

Try changing the fuel filter. Had a neighbour get a fuel rail pressure warning on his Peugeot after running it low on fuel and then topping the tank up …he had disturbed a load of grunge in bottom of tank that then clogged filter. A cheap and easy check. 2012 tdv8 Westminster arrived Jan 19 gone Dec 23

I can tell you the sorry story about my tractor.

Stuttered… fuel problem . Lots of mates looked at it , but to no avail & called the dealer’s engineer. The only way they could find out where the problem was by taking a spare fuel supply in a tank and introducing it at different parts of the fuel line.

In that way they identified the area , a super expensive u turn in metal. Before they jumped to order the spare part , the engineer examined it and found a split washer, that was letting in the air. So for ten pence and time spent , the issue was fixed. Filters are in fact so good that in certain circumstances, when the ambient air is already polluted, a diesel car will tend to extract more particles from the air than it emits. Emissions Analytics worked with........etc etc

He who dies with the most toys wins...

Whilst not the same fault code but worth checking the connector to the HPFP pressure sensor as it is known to cause erroneous pressure readings.

fixed. Thanks for the help

Turned out to be the secondary fuel pump. The only way we could find it was trace the fuel pipes from the tank and remove where we could to see where the fuel stopped.

Secondary fuel pump was on the bulk head under the fuse box and ECU.

There was a similar problem on a youtube post called `Saving salvage` they found it to be the second pump, a right to get to.
