i have a 2000 tdi beetle. It’s got almost 300k miles on it but the top end was rebuilt about 50-60k miles ago. Almost everything everything has been replaced under the hood as of now. I went on a long road trip with zero issues and 5 days after I arrived, it just cranks and won’t start. It first pulled a code for the water temp sensor, I replaced that. Still no start. Sounded like it wasn’t getting fuel. Checked the shut off solenoid it was bad so I replaced that. In the mean time my battery died so I replaced that. Still cranking with no start. I checked/replaced fuses. The 109 relay and the fuel pump relay. I used a vacuum pump to check all my fuel lines from the filter and the pump.. got nothing.  I’m torn between it being my fuel pump or a bad computer. I visually looked at my timing belt and it looks fine. I can’t afford to try a fuel pump or a new comp.. please help me!! I’m a single female and I just moved to a new state and I’m no car expert only learning as I go so please bare with me if my terminology isn’t correct. Thank you for any input! This is my daily driver so I’m car-less until I get this sorted.
