A mate has just bought a P38 GEMS Range Rover fitted with what appears to be a Prins VSi system (at least the switch has the Prins logo on it, there's 8 Keihin injectors under the bonnet and what looks like a Prins reducer but the label can't be seen on the controller). No problems with it running, pulls like a train and doesn't run out of puff up to the red line despite the engine having been fitted with a lumpier cam and Stage 2 heads, the only problem is hot starting. If he stops for a few minutes it is very reluctant to start so he has been switching back to petrol just before turning off. Then it will start first time and switch back over to gas almost immediately. My first thought was gas leaking into the manifold through an iffy diaphragm so we took the vacuum hose off (Tee'd into the vacuum line between the plenum and petrol pressure regulator) and put the pipe in a glass of water expecting to see bubbles but there were none. The injectors sound fine, beautifully quiet in fact so I can't see it being a leaking injector (especially as they are Keihins) but is there anywhere or anything else that would cause the problem?
