Above link explains what to look for so have you gone through them and confirmed the fuel pump is at fault? Testing of fuel pump operations can be done via the Fuel Pump Test/Prime Connector on left inner fender panel.

Guessing and changing components without testing and confirming can be a waste of time and money.

FUEL PUMP

Removal & Installation

1. Disconnect negative battery cable. Relieve fuel pressure. Remove filler neck. Lower fuel tank. Disconnect fuel lines and electrical connection.

2. Remove fuel level sending unit and fuel pump retaining bolts or cam lock ring. Lift assembly from fuel tank and remove fuel pump from sending unit.

3. Pull fuel pump upward while pulling away from bottom support. Use care not to damage rubber insulator and strainer. To install, reverse removal procedure using NEW "O" ring and gasket.

The link is to find out what is missing. After trying out the link, what did you find out is missing? Ignition sparks, fuel pressure or what?

You had been warned against replacing components without any testing.

If you are having fuel and sparks, why did you replace the pump?
If you have fuel pressure, there is no need to test the fuel pump any further.
Have you tested the compression?

With fuel pressure, injectors firing and ignition sparks, the next step would be to test the compression.

P052 means the battery had been disconnected. I can't find any reference to i052.

PCM is the engine computer.

You would need a conmpression tester to check the compression.
