Technical Not starting when warm.

[Dizel8]

1981 Spider, Fuel injected. Starts right up when cold, runs like a top, but hot starts are an issue. Cranks like a champ, but doesn’t start. Let it cool, start right up.

Suggestions as where to start troubleshooting?

Whilst it's hot and faulting , you could check/confirm for good spark, then devise a method for checking fuel flow (safely!!)

Either will stop it starting.
