This will be
1- Injector gone bad
2- wiring loom gone bad.

But also EDU, ECU could have gone bad.

You need to take engine cover off,
Unplug and reseat all the injector wiring harness.
Look for any damage.

if the problem is still present, you need someone who has the diagnostics machines to
read live data from the obd2 port.

Thanks this is a good start, I,m also told it may be supermarket diesel causing tank pick-up fault and poor fuel pressure.

could be,
But its not really a fuel pressure fault.

Replace the easy and cheap parts first.

1- Fuel filter
2- Check wiring loom
3- check connectors to edu, ecu, injectors.
4- get car onto a diagnosic machine and read live value.

when checking connection to edu and ecu.

Make sure to have ignition OFF and with battery + unplugged

You must let the system discharge.

or remove the injectors and have them all tested / refurbed
