Vauxhall zafira 1.6 petrol 2009 cuts out won't start

Does anyone know what the known repair was to Steve's fault as I have an identical fault on a vauxhall zafira 1.6 petrol 2009?

Cheers

Hello all,
This car is fixed just want to know how others would approach a fault like this.
Car is a 2008 Vauxhall Zafira 1.6 petrol UK model, engine code Z16XE1, similar to Chevy Cobalt I believe.

Customer complaint is the car would randomly cut out and sometimes wouldn't restart.
When trying to restart the car it wouldn't crank, after leaving it for a short while it would start back up but with check engine light on.

I scanned for fault codes and got
P0201 Injector cylinder 1 malfunction
P0202 Injector cylinder 2 malfunction
P0203 Injector cylinder 3 malfunction
P0204 Injector cylinder 4 malfunction
P0230 Fuel pump primary circuit low
P0650 MIL circuit malfunction
P1600 Replace ecu
U2103 CAN-Bus circuit malfunction/no comms

I cleared the codes and left it idling, after a while it cut out and when I went to restart it the car wouldn't crank just like the customer said

Went to check for fault codes and I couldn't communicate with the engine ecu, all other modules talked fine but they had fault codes stored for a no comm with engine ecu.

After a while I tried again and this time I got comms to the engine ecu, the car then would crank and fire up but had logged the exact same fault codes again.

I ended up spending quite a bit of time on this one and interested to hear how others would attack a problem like this
