Ford Transit TDCi 2.2 (110 T260) - Low / no rail pressure #

Posted by Shaun Dale on June 19, 2012, 6:06 pm

Year of Manufacture *: 2007
Engine Size and Code *: 2.2l

Vehicle cut out on the road and was recovered to the workshop.
On cranking there was no common rail pressure on live data.
We found the fuel was a milky yellow colour (in fact a friend of mine pumped 25 litres out of a car he was selling and it was the same colour, but that was an old Citroen ZX so it probably didn't care). So it seems that we have a fuel contamination issue. I fitted a squeeze bulb between the filter and the pump and found that the engine will run if I keep plenty of pressure on the bulb. When I stop squeezing the engine will sometimes continue to run but usually stops as fuel rail pressure slowly decays. I will give the pump a temporary supply of clean fuel tomorrow. No evidence of metal particles in the filter by the way. In the meantime I am concerned that the tandem lift pump is failing would this be reasonable supposition?

Note: pumps will draw whatever is easier, air or fuel.

Check the supply line with a mity-vac.

Hello,
my opinion is and i may be wrong but the pump is specifically designed to pump diesel and because that is not diesel it will struggle to pump what ever that is to the required pressure, i feel that some of the fresh stuff will cure providing no damage to the pump.
cheers

Thanks for the replies.
I have since run a temporary fuel supply and the symptoms have not changed.
There is very little fuel flow on the return line, I cranked for about 10 seconds and got perhaps 30ml returned. Does anyone have a figure for the flow rate? Before I go for a new pump I think I should check for drive signals on the IMV and fuel pressure regulator solenoid but would either of these give symptoms such as these?

Update on this one:
Unwilling to condemn the high pressure pump without further justification I took the IMV off and bench tested it to find that the plunger was sticking. Worked the plunger by hand until it freed of and refitted it. Engine now starts and runs fine both at tickover and fast idle. New IMV going on in the morning then! I will drain the tank and put in some fresh diesel as a precaution anyway.

if i were you i'd advise the customer on the possibility of further problems with the fuel system in the future after running on that crap

Hi Shaun
Out of curiosity, did you find out what the contamination is, or is that a question better not asked?

Hi Guys,
Vehicle now back with customer with a suitable bill. He called me at 6:45 just as I was locking up to go and recover him from 5 miles away, he obviously thought Autoelectrician abbreviated to AA!
Back to the fuel. On the left was fresh fuel drawn directly from the forecourt pump. In the middle is an original sample drawn through the fuel filter and on the right is the same fuel photographed earlier, the water in the bottom is where I drained the filter checking for metallic debris and water. In retrospect I should have drained it into a different container, too late now. The strange thing is left open to atmosphere it has cleared whereas the sealed sample has not.
It also turns out that the fuel my friend drained from his vehicle came from the other filling station in the town not the one my customer used. These samples are Esso, the other filling station is Harvest. It also appears that the fuel in the 25 litre drums is clearing slowly.
Sorry about the image size, tinypic seems to throw a strop when I ask it to resize!

Hi Shaun,

We had a Nissan Kubistar 1.5DCi in recently that had fuel similar to yours in it my customer swore to me he had bought it from a fuel station! (no idea which one though) This one had a pump and 2 injectors to sort it but even seized our workshop electric pump when emptying the tank out!!
