Cranks but wont start when hot after driving for a while, such as when refuelling.

Ute drove to us after being started. Found no 1 and 2 injector seat seals blown leaking combustion gases coke and carbon everywhere. Cleaned up, re-seated injector seats, had injectors tested new seals washers. Started first crank, road test good, checked when warm started OK. Customer took on long drive first refuel would not start

RACV called and pumped filter primer started after awhile off pumping and cranking glow plug light coming on as normal.

Towed back to us no codes no leaks starting OK now cold.
