Not starting

[mark 05]

Hi i have a vt the car was starting good as gold and now it won't start.
The thing is it wants to start but its like its starving for fuel. Fuel pressure is good i have changed spark plugs.
Just wondering before I go changing the cam or crank angle sensors could it possibly be one of them. Or something else.
Thank you

how have you determined fuel pressure is good?
remove air filter and spray some brake cleaner or similar in whilst someone else cranks
or use a petrol soaked rag
(trying to introduce flamable fumes into inlet)
