I know, I know - trying not to believe in Bad Magic, but after chasing all these ingredients for a couple of weeks, you get a bit phased. Spark we have, but not ignition. But how could the spark have ended up in the wrong place while travelling along steadily?
Latest scenario I'm trying out : When it stopped, the most obvious thing was the braid attaching the coil block to the cylinder head had worn/corroded away. At the time I though it was vital to the spark return, before I found out about the dual-action wasted spark idea used on these models. So I replace the earthing strap to the coil block.
Subsequent examination of the coil - it looks really ratty, with cracks in the sealing covers on two of the coils.
Perhaps I had a relay problem as suggested the most common cause of failure while running, and I fixed that, but in the meantime replacing the failed earth strap earthed the previously isolated coil block, allowing the high tension to bleed away with consequent loss of spark.
I other words I cured one fault and replaced it with another which was waiting to happen
, and then in the mean time flooded the cylinders.I'm trying out this theory (coils all test correct DC resistances) by dousing the coil in silicone oil to insulate and inhibit tracking and insulating it from vehicle ground. So far no start but I need to clear the excess fuel from the cylinders to give it half a chance and it's snowing now....
Anyone got a good, spare V6 coil PM me with price, or I might have to go to the extreme of buying a new one if they are still available. Does the 156 V6 use the same one??
Cheers all, what a saga
