93 Volvo 940 starts, runs for 30 seconds, then dies

Hey guys! I recently took apart my 93 940 cause a hose broke. Now as I put it together it only runs for 30 seconds then dies out. It ran prior but with a misfire and I think a 1.3.1 code for fuel. Vacuum is good while running and no misfire. I took off the fuel line and cycled the key three times and about a cup of fuel discharges. Fuel pressure regulator holds vacuum as well. All sensors hooked up as well I know it’s not something I missed.

New parts:
Fuel pre pump
Coolant temp sensor
All new vacuum lines
intake and boost hoses
ignition cap+ rotor
spark plugs
Throttle body gasket
Clean throttle body
Thermostat+ housing

Any help would be very much appreciated!

Fuel pressure holds ... vacuum?

Connect a fuel pressure gauge to the fuel rail and watch the fuel pressure as it runs.
