D16y7 Will not start HELP

[g0sammo]

Hoping someone can help me out here I'm at my wits end!

So my car has been built for a year or so (speedfactory rods, vitara pistons, stock top end), haven't had any issues with it and drive about every day. It sat for a week or so then i started it to move so i could mow near it. Started up just fine, moved and I shut it off. When i went to move it back to its spot, it just cranked and cranked and would not start. I connected my phone to see if was throwing any error codes because the check engine light would pop on for a second then go right away. The only code i ever caught said Unknown Error, didnt catch a code number as it went away pretty fast, and I havent been able to duplicate it and i get no other error codes. I checked and my fuel pump is working and have good pressure to the rail. I sprayed starting fluid directly in throttle body to see if maybe my injectors aren't working and still did not try and start which led me to believe it may be an ignition issue. i swapped in a known good distributor and still no change. checked with a timing light and i am getting spark. Pulled my plugs and they are black but probably just from me cranking on it so much. I was afraid my timing belt may have jumped so i pulled the cover and double checked that my timing belt is in good shape and my marks still line up. Ran compression test and all cylinders are up around 160 range. So if im getting spark, fuel, have compression, and no check engine lights showing a sensor is going crazy, what else can i check? Im attaching a short datalog of me trying to start it incase someone may be able to see something in there that im missing. Thanks for any help!

You need to check for spark by removing the spark plug and grounding it and seeing if there is good spark.

You should also try the ECU in a known working vehicle to see if it will run a different vehicle.
