Hi all.

Have had a problem on two occasions recently, both requiring RAC call-out (only for it to start when they arrived !)..............anyway, the car starts fine from cold and runs fine (although a little lumpy at tickover on LPG - no surprises there), but I'm having a nightmare whenever I've stopped the car and left it for 30 minutes or so..............................refuses to fire up !

Turns over, but doesn't even cough. Tried some 'engine start' yesterday (after walking around for miles in the pissin' rain, trying to find a motor factors), , thinking it might be the 'choke' getting itself confused, to no avail. RAC guy turns up about an hour later and hey presto..........it starts after a couple of turns !

Only faults showing on their diagnostic are lambda sensors and a MIL fault (which I think is something to do with the LPG switching), which wouldn't affect ignition.

Any ideas ? Crank sensor perhaps (although no fault shown) ?

Don't really want to get rid, as it's pretty economical on LPG, but can't be doing with the hassle of this every time I leave the car for half an hour !

Ta.

My crank sensor failure showed no code, just occasionally a gearbox problem displayed on the MID. 

Alright when cold, engine would cut out when hot and then start again when colder an hour or so later.

Certainly the symptoms of crank sensor.
