XK8 starting issues

Hi people I wonder if anyone else has this issue with their XK8. I have a 1998 XK8 which start beautifully first time every time but only for the first time. If I switch it off once up to temperature and then try to restart it either straight away or within 10 mins of switching off she just won’t start, turns over but doesn’t fire up. I literally have to wait for an hour while the engine cools then she starts beautiful again. This is annoying as it means the wife has the perfect excuse to wonder off to the shops and spend money while waiting for the car to cool down lol. Any ideas?

I think you need to post this in the XK8 section. This is for the XK120 to 150.

I believe there is a solenoid on the high pressure fuel line that preserves the fuel pressure when the engine is hot. If this is not working then the car will not start until the engine cools down.

Thanks I will look at that,have also reposted this on the correct section but wanted to thank you for answering despite meputti g it in the wrong section
