• Vauxhall Zafira A (1999 - 2005) - 99 1.6 Fuel starvation? 11 Jun 2011 (Forum)
  The car was serviced last month but the Vauxhall dealer failed to sort the problem - all they suggested was to replaced the fuel filter which didn't cure the problem. Has anyone heard of this problem before, or know if there are any vents in the fuel sysytem I can check? Although this is an annoying fault, I am concerned that it could happen whilst overtaking or in the outside lane of a busy motorway as the loss of power comes without warning; the only way to prevent this is to drive with the filler cap slightly loose!
• Rover 45 (1999 - 2005) - 03 1.8 Fuel Gauge Calibrations, what do they mean? 12 Mar 2008 (Forum)
  On my 2003 1.8IXS the instument dials are white. Now, the fuel gauge has two black dots on the right of the gauge which must just be the fixings? or do they mean anything? There are then two lines , one at about 'twenty to' an one at about 'ten to'. Are these indications of empty and full, as when the gauge drops to the lower line or thereabouts the little yellow petrol pump light comes on (intermittently), but there is still a long way to go to the right of this line and I am afraid I will run out of fuel.
• Suzuki Ignis and 98Ron Fuel 18 Jun 2005 (Forum)
  One's no supposed to read the book!) It states that only 98Ron fuel and above is to be used. This is re-iterated on the filler cap. I've been using Optimax as the only 98Ron fuel around, but now there is a new kid on the block - Tesco super is now 99Ron, and slightly cheaper (86.9p/l in Tesco Extra - Camberley/Blackwater) than Optimax (Around 89.9p/l in Fleet and around 85.9 in Portsmouth).

• Semi-automatics. Real fuel consumption 9 Apr 2011 (Forum)
  We are used to understanding that real world fuel consumption figures can be worse than the official figures for manual cars, so we can factor it in when choosing cars.   But what about semi automatics?   Do we get an extra hit on fuel consumption if we drive in full automatic mode?

• Nissan Almera Tino - Fuel pump problem? 2 May 2015 (Forum)
  If the information helps, on one occassion when I phoned the AA to start it, he 'manually primed' the fuel pump (?) and it started straight away. It has been to 3 different garages (including a main Nissan Dealership) none of whom have been much help. The glow plugs have been changed (no difference). Despite several diagnostic tests the best advice we can get is that it MIGHT need a new fuel pump.
• Peugeot 307 diesel 2 Litre HDi - Can you make a Peugeot 307 fuel supply foolproof? 21 Apr 2015 (Forum)
   They were expensive to correct as diagnosis was often flawed. It turned out that a frequent cause had to do with dirt in the fuel, resulting from bad handling of a fuel filter replacement. Screwloose advised not changing the filter cartridge but instead changing the whole filter. As this would be a costly move, he must know there is good reason for it.

• Renault Clio 1.2 16v Petrol 2003 - Renault Clio Car wont start, got spark and fuel 18 Dec 2012 (Forum)
  Hi there all mechanics, I have a clio 1.2 16v Petrol 2003 model that wont start, the problem is sometimes it starts and other times it wont. It has a good spark and plenty of fuel pressure going into the rail but wont start  most days. I have a spare fuel rail with injectors in it and have tried using it as a slave which I have connected to the fuel line and then taken off multiplug to No 4 and connected it to the slave and when I crank it over nothing comes from the injector.
