• SAAB 9-3 (2002 - 2007) - 2003 2.2 TID - loss of power 25 Feb 2014 (Forum)
  Still wont start.... Had a look round the car etc and seems that no fuel is getting to the fuel filter.... Put diesel straight into the filter and it seems to try and start easier, but wont actually start. Looks like the fuel pump. Any ideas on that?

• Peugeot 307 2. 0 HDI Xsi 136 - PEUGEOT 307 HDI HOT STALLING? 25 Sep 2012 (Forum)
  I foolishly lent it to a friend who accidentally filled it up with petrol and then continued to drive it without realising. After cleaning the fuel out and refilling with fresh fuel the car still would not start, and even after towing to attempt to bump start it still would not start. The Cat was replaced, the injectors were replaced and the DPF filter was cleaned through with a jet wash and then with DPF cleaner.

• Volkswagen Bora - Fuel consumption 17 Jun 2010 (Forum)
  The question is: Can a sticky turbo vanes or bad MAP sensor cause this symptons? I mean the increased fuel consumption and the bit black smoke. The weird thing is when I get first time limp mode,there was not black smoke or increased fuel consumption.I have just realised since the turbo has been cleaned with innotec cleaner.
• Renault Laguna II - Laguna 2.2 dCi VERY high fuel consumption 20 Mar 2010 (Forum)
  Before I start, yes I got a Renault, bad mistake so I dont need any of that information :D For a while now I have been getting really low fuel economy on my 53 plate Laguna 2.2 dCi. Hoping you guys here can provide some suggestions. The official figures are around 33/43/53mpg for town/combined/motorways respectively. Got the car in June and for the usual commute (90% motorway, 10% town) it was averaging around 45mpg.
• Mondeo s reg. Significant fuel leak 13 Jun 2006 (Forum)
  Haynes says remove the tank first before dealing with them. I am hoping it is just a pipe come off. When fixed it should improve my fuel consumption a bit.
• Are speed ramps killing my fuel economy? 13 Apr 2003 (Forum)
  I usually have to slow to about 10mph to take them. It occours to me that the reason for my shocking fuel economy when at home could well be the slowing down and subsequent speeding up from using these speed ramps. Am I on the right lines here? Could it make such a difference? Also, what effect are these ramps having on my car?

• Vauxhall Astra F (1991 - 1998) - 1996 1.7 TD - Intermittent Starting Fault 4 Feb 2017 (Forum)
  Sometimes it will start first time others it may take a good few attempts but nearly always when it does start it's within a few seconds of turning the key i.e. increasing cranking time does not have a positive effect. For this reason I suspect the problem is with the immobiliser and not air in the fuel/backdraining or glow plugs or starting / charging system. There was a problem with the main fuel shut-off solenoid but that was more that it wasn't shutting as opposd to not opening. The plunger has been removed to bypass it at the moment and the engine has been starting and stopping on the immobiliser solenoid.
