  What's the fuel economy of a diesel Hyundai iLoad with a light load?
• Honda Civic 06 2.2 Cdti - Honda Civic 06 Fuel Starvation 26 Nov 2015 (Forum)
      Problem occurred last year about the same time when temperature dropped below 8 degrees the car become hesitant when accelerating from junctions some times conking out or slow moving as if starved of fuel, the same happens when travelling in slow moving traffic then accelerating to overtake then when you move back into a slow moving flow and go to accelerate it conks out or becomes slow moving.   Checked out V.O.S.A website and found that there was a recall on fuel pump for this model and year but Honda says that my car is not affected by the fault, the car has been serviced EGR cleaned, new fuel filter( not Honda).

• peugeot 306 hdi - fuel pump primery curcuit 6 Mar 2011 (Forum)
  i have just bought a peugeot 306 hdi, after having it about a month the engine manegment light came on and the car cut out, i thought it was the diesel because it was very low so i put some in and it still would not start, i had it put on a diagnostic computer and the code was po230 fuel pump primery curcuit, he cleared the code and the car run for about 1 hour so i was told to change the fuel pump relay which made no differance at all so i tryed a fuel pump (the one in the tank) but still no joy, now the car will only start for about five seconds before it cuts out but some times it will tick over for a while but when i try to rev it it cuts out and plus it would only rev to 2500 rpm and when i switch it off with the key it over runs for about 4 second. i hope some one can help as i dont know what to do next. thanks

• BMW K100 RS 8v 1985 fuel/ECU breakdown 8 Jun 2009 (Forum)
  On way back after ~10 miles, with water temp at 80C and no problems it suddenly died. Fault traced to fuel pump relay not functioning. It works if we earth the yellow & brown cable which goes from connection 85 of the relay to connection 7 of the ignition control unit. Manual suggests "fuel supply will be shut off" if there is a high water temp, or other fault which turns off ignition, but I assumed this would mean isolation of the injectors usually.
• Mazda Mazda 6 (2008 -) - 08 2.0d erratic fuel consumption 28 Apr 2009 (Forum)
  I have had a 2008 Mazda 6 diesel for a year. The fuel consumption in general is very good until the car decides to rev higher than normal. I keep the computer set for average fuel consumption because of the infuriating problem the car has. On a long journey the mpg gradually increases and then all of a sudden it starts to drop.
• Every cloud.... fuel prices. 2 Oct 2008 (Forum)
  All in all, I think my fuel costs have actually gone down - with no apparent loss of function or pleasure. It's almost fun being more frugal & getting the same (lifestyle) for less.
• Peugeot 206 hatchback (1998 - 2006) - 54 1.6 hdi 110 fuel consumption change 28 May 2008 (Forum)
  Hi im lookin for some advice. Iv only had my 206 GTI hDI 110 for around a month now. At first i was very happy with the fuel economy! The last few days whilst driving all of a sudden the fuel consumption drops to between 38-42mpg. (yes on instant MPG) when this happens the average MPG drops down and so does the miles left to empty!
• Citroen Berlingo Multispace (1998 - 2010) - 1996, 1.9d, fuel pump/ immobiliser 22 Mar 2008 (Forum)
  i am looking at this for a friend - he had the immobilser by-passed by his local garage. A ignition-switched supply was connected to one of two leads to the fuel-cut off solenoid - behind the cover on the lucas fuel pump. Several other wires in this region (not all) were cut at the same time. At the same time, a "miss" developed when under load. There is a four way connector that connects in front of the solenoid.
• Ford Fiesta (1995 - 1999) - 1998 1.3 - Engine trouble 22 Feb 2008 (Forum)
  It appears that there is minimal fuel pressure building up but the fuel pump is operational! Can anyone help me out please? Cheers (someone else who hasn't managed to grasp that they should put the year & engine details in the subject header )
• Vauxhall Corsa B (1993 - 2000) - 1993 1.5d Bleeding Diesel fuel filter 27 Jan 2008 (Forum)
  My hubby has a 1.5D Corsa, on which he changed the fuel filter yesterday. According to the manual, there is a bleed screw on the top of the filter housing, which you bleed until it flows with diesel, to ensure no air in the system. He tried this, even taking the screw right out instead of the 2 turns the manual recommends, and no fuel appears.
• Peugeot 205 (1983 - 1997) - 1.9 GTi overfuelling 10 Sep 2007 (Forum)
  Where is this relay on the vehicle, I have spoken to my local dealer who do not have a clue!!! Could this be causing the problem? Is it true that the fuel pumps are either on or off on these? Should it be supplying a constant run of fuel across the rail? The only thing i can think of is maybe the coolant temp sensor but the worry i have is the amount of fuel it is pumping, it quarter fills a 5 litre jerry can in about 20 seconds of cranking!
• Vauxhall Astra Immobiliser?? 18 Sep 2006 (Forum)
  Guys, I have an 04 Astra 1.6 SXI which is giving me a major headache, the car was driving fine until yesterday after which the vehicle refused to start, it will turn over but apart from that I am getting absoulutely nothing, I therefore: Checked that power is going to the spark plugs - it is. Checked the fuel pump - No power was going to the fuel pump I then bridged the fuel pump relay and the fuel pump ran OK (didn't try starting the car in case I damaged anything) From this I concluded (rightly or wrongly) that either the fuel pump relay is not working or the relay is not receiving a signal from the ecu to "switch on" the relay and allow power to run to the pump.
• Renault Espace 22 Oct 2004 (Forum)
  The engine turns over, fires and runs for about 3-5 secs then cuts out. When the ignition is turned on you can hear the fuel pump running and after the engine dies the fuel pump still appears to be going. If carburettor cleaner is sprayed down the air intake, the engine will carry on running, suggesting that the fault lies with the fuel system.
• How to Cut Fuel Prices 4 May 2002 (Forum)
  No one needs to stop buying fuel. All we need to do is collectively boycott the service stations of the two leading oil companies and buy our fuel from their competitors. Faced with a near total collective boycott of their product, the two leading oil companies will have no alternative but to cut prices, which in turn will lead to a price war, which in turn will pull retail prices back under 70p a litre.
