It's supercharge. Checking the fuel presser, turn the key on and it go to 50 - 52 PSI but in 30 seconds it goes to 0.

Hi Mike,

Just so I am clear, are you going key on engine off and it goes to 50 then after letting it sit, it goes to 0 or are you starting the car and it goes to 0 and the engine stalls?

If it is the first, then you have a leak externally or a bleed in the system allowing pressure to bleed off.

Let me know and we can go from there.
