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

[Ryo]

I will check the gauge if it is okay the cam timig was okay the engine is having 188tkm. I have finally found the issue it was in clogged fuel injectors using carb cleaner done the trick all is running smoothly as before maybe even better.So my AE86 is repaired. Thank you for all the valuable information.

Now i can return to original issues for that i opened this topic with my friend AE86 as it seems the trouble is still there and the engine have problems to run correctly. I will check the compression gauge and start from checking on his engine compression. Betting that there can be simillar problems like on mine as the car was not moving much last 3-4 years.
