Then the engine fuse may be blown it will be marked ECM I think, the fuel pump and injector circuits are two seperate systems, the fuel pump most likely has a stuck relay.

Do you have the fuel tester hooked the in the overgrown air valve on the fuel rail in the back of the engine? Or do you have the fuel line unhooked in the back and hooked to the pressure pump? You want the fuel pressure to be in that 60 lb range so if you are hooked into the pressure valve on the fuel rail allowing fuel to go through, then I am betting it is the fuel pressure regulator. To get to that, you have to take the throttle body off and take the plastic plenum that covers the injector packs. On the back of the mount where your six pack of injectors are sits the pressure regulator. If it is faulty then it is dumping fuel instead of holding the pressure like it should.
Get a Chilton or Clymer manual and it shows you in pretty good detail how to fix it. I've done it to my 98 S10 with the same engine.

If you unhooked the fuel line so you are losing pressure from the line back to the pump then I would say your pump is letting fuel back to the tank when it shuts off. My money is on the first possibility though.

Good luck

SOURCE: wont start. has spark, fuel to fuel rail, new TPS,

Check injector pulsation at injector harness with test light, with key on, disconnect harness at injector check for voltage, then reverse test light at battery and on the other pin check for ground pulsation while cranking engine, should have pulsation, if none bad computer, injector pulsation control by computer.

2019 Cadillac Escalade ESV shows P00CA code and goes into limp mode. New high pressure fuel pump and the fuel rail pressure sensor was replaced.

Fuel Pressure Regulator High Control Circuit High Voltage
High Control=Short to Voltage-For greater than 4?sec

but did you reset all DTC after new parts
using button on tool with that name.
the drive and see if i came back this error
if yes.
then fuel pressure is tested per the service guide.
pin 16 is shorted (F)

here it is, the DTC means this node p16 is shorted to a voltage source.(wrongly)
see PIN 16 here.

Code PO 193

Fuel Rail Pressure Sensor Circuit high input.
1. Unplug the negative battery terminal connector (black one, NOT red) from the battery and set aside. Doing this will also reset your check engine light as well.

2. Unplug the fuel pump fuse. Check owners manual for proper location in underhood fuse block.

3. Start vehicle and run it until it dies to relieve pressure.
4. Disconnect the electrical connector to the sensor on fuel rail.

5. Remove bolts to fuel rail pressure sensor.

6. Disconnect hose on back of Pressure Sensor.

7. Once everything is disconnected, pull straight up on sensor. Be sure to pull up with a little effort, it has a snug fit. Of note, you will see gasoline when you lift up the FRPS so be careful so as not to let debris fall in there.

8. Install new FRPS and reconnect hose and electrical connector.

9. Put the fuel pump fuse back in.

10. Reconnect negative battery terminal.

11. BEFORE YOU START THE VEHICLE, you need to prime it. Do this by cycling the key to the ON position and Off position several times for the fuel pressure to build back up . Do this 2-3 times then start your vehicle.
CHECK FOR LEAKS, TEST DRIVE FOR ABOUT 10 MILES OR SO AND BE SURE EVERYTHING IS OK AND CHECK ENGINE LIGHT DOES NOT RETURN.
