I may not do it correctly, could you please advise the procedure of how to test them?? https://www.dropbox.com/s/ydmsnanxqs...71_15.jpg?dl=0 Also, I'm a little bit confused about what the coils are. It's the red one or the blue one. We tested the red plug |

The item which you've circled in red, and which you now say you've tested, is a sparking plug. The item circled in blue is an ignition coil. To test a sparking plug it must be unscrewed and, with its lead reconnected, laid on a conductive and earthed part of the engine so that the plug body makes good electrical contact. The engine is then cranked briefly and a spark should then be seen between the centre electrode and one or more of the side electrodes. Make sure that you don't do the test in bright sunlight! So is that what you did Richard and you saw no spark? As I said earlier, you should not hesitate to check the fuel filter for loosening ("fuel filter syndrome" or FFS). Simon

Thanks for the clarification and yes that is what I did and saw no spark. The roadside assistant also did the same test but use their own taster (looks like a gun with an indicator ) before towing the car. Could you please guide me to test ignition coils? thx Richard |

Hi Richard,
All you can practically do with the ignition coils is to (1) check the DC resistance of the primary winding and (2) ensure that a 12v supply is reaching the connector. To measure the primary winding resistance remove the connector and place your meter between the coil terminals 1 and 3. It should read 0.77Ω ± 0.08Ω but don't be too precise about it! The supply appears on connector pin 1 (brown/pink wire) from fuse 2 in the engine compartment fusebox. Use the battery negative terminal as your earth. Please report back with your findings for all three left-hand bank cylinders. Simon

O.K.
Forget about the spark for now and concentrate on the fuel filter because your symptoms suggest that it's separated. There's a knack to lifting the rear seat cushion and you'll find some tips hiding on the forum. The filter's on the left hand side and secured with a large ring. Don't undo any connections but carefully lift the filter canister just enough to check that it is tight. Photographs of this have been posted. Do not separate the filter assembly. If there is no clip fitted, order one! Please make a start on that Richard and come back to us if you meet any problems. Simon

Are you sure that you're not thinking of the HP fuel sensor on your diesel? Simon
