Vx not starting

[jaxonmicallef]

hey guys
i have a vx commodore (can be ran on gas) that’s giving me a whole lot of dramas, to start with it’s not starting, i have replaced the fuel pump and filter then replacing the ecu bcm key barrel etc, i’m pretty positive it’s a fuel issue, maybe injectors are closed for the gas, it’s really got me stuffed, i did get it running finally and just needed a battery because i was borrowing one, i bought a new battery and now it’s not starting again,
if anyone had any idea could you please share them with me

Fuel at the rail?

Because you mentioned the key thing - is the car starting and then stalling, or just not starting at all? When you had it running last, was that after you changed the key barrel?
