Cannot figure out this crank no start.
Car is a 2001 Prelude with JDM H22a. OBD2 block, p28 hondata ecu, obd1 dizzy
I have done the following:

Replaced distributor/CPS (obd1 ecu)
Replaced ignition switch
Replaced all grounds
Replaced ignition switch harness
Replaced battery
Replaced starter
Replaced Spark Plugs
Replaced Fuel Pump
Replaced Main Relay
Replaced Fuel Regulator
Replaced gas in tank with fresh 93
Cleaned and tested injectors, all are good
Tried replacing ECU
Confirmed good compression
Confirmed spark
Confirmed good mechanical timing
Confirmed Fuel pressure at rail
Confirmed all 4 injectors are getting signal w/ noid light

At this point I'd send a cash reward to whoever can help me figure this out lol. Everything is there for the car to start but it wont. I can get it to idle shortly on starter fluid which is why I replaced all fuel components but still wont start. Took it out tuning the day before and everything was fine. Went to start the next morning and all this started.

Thank You
Guy

Maybe a squirrel filled your air intake with nuts? Make a video of you trying to start the engine. The sound of it starting might give a useful hint. Also let this be a lesson not to just hit the car with a parts cannon when something goes wrong.

What all did you do the day you took it out "tuning"?

Have you tried converting back to obd2 and seeing if it runs?

Almost sounds injector related. I would test them differently.

Definitely sounds fuel related if it really does run on ether. Plugged filter or clogged injectors. He should prob get em flow tested at this point.
