Hi , i was wondering if you guys would be able to help me again, oK Land Rover series 3 petrol had starting problems so i replaced the following : points, distributor leads, alternator, all the earthing straps and added an earthing strap from the back of the starter motor to the chasis, oh and also the battery for a new heavy duty one.

then for a week started fine hot or cold , wet or dry.

but this evening on way home started fine, drove for about 1/2 mile and engine cut out, plenty of petrol in it.

turns over fine, but will not start.

any ideas
