Hello,
I have had trouble with this car, and in the last fortnight have come to
the conclusion the I have timed, ample sparks, and fuel but no
combustion. I have cranked the car until there is petrol in the throttle
body, dried it and the plugs, tried easy start ( and gas on its own, as
it is converted, I know the system cus I fitted it
) and still not a
hint of a detonation.
coil changed
ballast resistor removed, swapped, swapped again.
ignition amp changed (found a 3 wire one fitted , with only the outer 2
wire terminals employed, but this car has done 20,000 miles or more
around my person, so this sudden shutdown is a surprise.
I swapped the ecu from my suspect range to another, and it works fine.
I am at a loss, as you might imagine
I have spark compression and fuel with no combustion...
All the best
Bernie
