Fg falcon dedicate gas turns over but wont fire

Hi all,

Have a fg dedicated gas falcon xt.
Car currently will turn over but will not start/fire. Have replaced gas converter. All fuses check ok, relays all seem to be working.

Any ideas?

I'm only guessing but could be ignition coils /coil pack. But I'm unsure of set for dedicated gas. Unfortunately with gas I'd be less inclined to play with it, so I'd recommend getting it to workshop for them to look at it.
Was anything done to the car before it stopped starting? Or was it fine and just wouldn't fire next time u got in it?
