Cranks but wont start

Saxo 1.6 8v 99

2 Days ago my car didn't start. after some fuse checking and a failed push start i called the local roadside assistance, he hooked up my battery to his van and said indeed my voltage was low, after 1 min he said strart it and it started.

drove a bit, i had a P0604 fault code, he resetted it. we did a restart and everything was fine. now 2 days later my car again does not start. it does crank but not start.

i am not sure if i hear the fuel pump. will check asap when i am at the car.
What can be the cause?

Solved, car had issues for 2 days, fuel pump was not priming, fuse blown. new fuse and runs again
