Any advice gratefully received.

Polo Has suddenly died, Looks like possibly a distributor problem.

There is a healthy spark from the coil, but intermittent at the plugs (New dizzy cap and rotor arm. The plugs on removal are "wet" and I have noticed that there is a crack in the plastic casing of the trigger sensor.

Could a new trigger sensor be the solution?

Thanks

Hve you a strong spark at dizzy end of coil lead? If so and not at plug end of any lead, then rotor is suss. Leads break down earlier due to high kV (compared to earlier points triggered systems)You might have fixed prob with rotor
and cap but sometimes wet plugs continue to short out inside. Cap/roter may be tracked/burnt cos high kV can't get down tired leads/insulated plug caps.If the spark is orange, then suspect ignition amplifier tired. shouln.t get spark at all if trigger was u/s.

The spark is very strong from the dizzy end of the coil lead, but a bit weak on 2 out of 4 plugs.

I'll check the rotor again. In the meantime, any other suggestions?

change ht leads as a set. these cars with aex(1.4) engine are reknown for the spark plug caps which are metal tracking the spark to earth thus no go or misfire. if ht is getting back by tracking to the ecu the ecu will shut itself down to protect it.
make sure leads you buy are o.e. quality. if poss get ones with rubber spark plug ends not metal so prob will not happen again.
make sure to change plugs as well as they may be contribting to ht loss. check old leads for white spots in spark plug caps this is evidence of ht voltage going to earth.
