A: Hello - I think you still have fuel supply ...

Hello - I think you still have fuel supply issues - perhaps a leaky injector., or a weak fuel pump (you mention it is noisy). Backfiring is a symptom of fuel supply problems. Check for problem codes, whether the Check Engine light is on or not - these can be instructive. I would also check fuel pressure while running. I would recommend an inspection of the fuel and ignition systems by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
