My 2009 civic si cranks but won’t start

It’s not the battery or alternator I found out it wants to start but it won’t

Pull plugs, dip the cylinder with some sort of tool small enough in diameter to see if there is liquid fuel in the cylinder, but obviously something the won't fall in or get stuck.

-check all major grounds to the engine/block
- check all fuses/relays (you can buy a "test light" at any parts store, to make this cheap and easy)

-then check for spark and fuel.

I don't really see a need to jam a dipstick into the cylinder lol

I’m getting a p0602 code I’m thinking it’s because I plugged my Hondata in a couple days ago and after that is when it wouldn’t start

Undo everything aftermarket, put it back to stock and see if it returns to normal?

Hahaha, why didn't you meantime the tunner?

Did you ask hondata to load a base map? If so did they load a map for your current engine setup (stock/high comp/boost)?

My mustang had a similar problem and the spark plugs were out on cylinders 2 and 3, with the other ones being too weak. And a friend had a tune that got corrupted somehow and resetting his back to the stock map fixed it. That and it could be flooded. It sounds like the simple solution is most likely the tune since it didn’t happen until after the tune my dude...
