Fuel Pump not Priming Hondata S300

I have a 97 Prelude with H22a1 swap. I am running P28 ecu with Hondata s300.

I was having intermittent fuel pump not priming and now it's not priming at all.

I checked the main relay pins for voltage and I have 12v on all wires except number 7 and the ground. Number 7 shows no voltage when ignition is on start position which it should as that's the wire going to fuel pump.

I jumped the number 5 and 7 pin and the fuel pump starts priming.

But I still could not get the car to start with the Main relay pin 5 & 7 jumped & fuel pump priming.

There are no cracks on the main relay solders and I re-solder them anyway.
I checked the thermostat ground and its there.

How do I tell if ECU is bad or the Main Relay?
