AE86 4age engine not starts crank ok backfires to air intake

[Ryo]

So i have done compression tests and it looks following:

dry test (psi):
1: 165
2: 165
3: 160
4: 165

wet test with little oil (psi):
1: 260
2: 265
3: 260
4: 265

I think if i will be cranking the engine more maybe even more pressure will be built. There was no pressure drop on any cylinder.
What should be my next thing to check i can't perform leak down test as i don't have the tool for it.
I am thinking of cleaning AFM, throttle body than move to cleaning all the injectors.
