If you plug intp pp2000/Lexia Diagnostics ,

Fuel system parameters ,

fuel pressure refernce value in mbars will be the same value when you are cranking engine ,the two value`s will match,

if mbars are lower cranking then you have a blockage / leak/ or your fuel pump is not working right.

Need to check air, fuel, and coolant temperature signals too.
