Engine cuts-out
on my '96 940 auto, unexpectedly. New battery, fuel relay fine, and ignition current is reaching the coil. Been suggested it might be a sparking issue! Hours of fine engineers' efforts have not fixed it.
Anyone suffered from this phenomenon? any hints or tips gratefully received. |

When does it do this? Cold, hot, in traffic, driving at normal speeds, idling or what?
Also what year, engine, transmission etc?

On mine it was the crankshaft position sensor installed in the top of the bell-housing that developed an intermittent fault, probably in the wiring. Easy and fairly cheap to eliminate but not particularly easy to spot the first time you look for it.
Be carefull not to drop the screw bolt into the bell-housing or ease and cheapness dissipate rapidly. |

Need more information.
Is it after accelerating, does it restart ok? Does the tacho needle move when its cranking but not starting. Can you hear the pump prime? |
