2006 e53 4.8is crank no start

[Gilesd559]

I recently purchased a 06 4.8is , cranks but no start , I seen it run for about 30 minutes straight at idle then it died and won’t fire up any more, had just rebuilt engine and put it in , no codes popping up ,

Check the fuel pressure. No spark normally sets a code so no code check for lack of fuel pressure.
