Silly question, but are they the correct voltage?
I had a similar puzzle with a friend's car back in the UK, which 
stopped for no obvious reason with no spark. It was a 1958 Austin-Healy 
Sprite, with the tried & tested Lucas ignition system used in the 
majority of British cars of the period. There are only a limited number 
of things that can cause a loss of spark, but this was one I had never 
seen before - the rotor arm. Turns out they Chinese are making rotor 
arms which are prone to shorting out (grounding I should say) onto the 
center distributor shaft. This is recognized as a common problem today, 
and if you want a reliable ignition system you have to fit a red rotor 
arm. Not sure who makes them but they don't ground out like the Chinese 
Another problem that never used to exist is flexible brake hoses that 
get blocked internally or start working like one-way valves. I believe 
this happened when they introduced some sort of internal lining to stop 
them sucking in water from the atmosphere.
Progress I suppose?
