Problem 1 sounds like the spark on a cylinder did not light up.
Unburnt fuel went into the hot exhaust and popped. Backfires.
Had this happen to a mustang.
It was the little roll pin on the distributor gear.
Pin sheared and timing went to hell. A backfire and then dead..
Sometimes the pin would stick and it would start for a second then shut down just as quick

It backfired through the intake side

This is all guessing, ...
You have a different problem.
Backfire on intake side sounds like the engine timing is off
Did you check the timing belt?
Open valve cover and see if cranking engine moves the valves
If not then broken timing belt. I don't know.
Good luck to you. Hope it is a simple and cheap fix
