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

Do you have the necessary wiring/jumpers for your OBD2 harness to use an OBD1 distributor and ECU?

 

Was the car previously running on whatever calibration is flashed on the P28?

 

Damn that’s a pain. Honestly it seems you have everything. I would for the **** of it test another ecu, dizzy and a new battery.

 

Start it and keep the key in start position so the starter motor keeps trying to start it, not for too long though because the starter motor can overheat. Observe and listen for what you car is doing during continuous starter motor engagement. This could reveal a path.

Show us a video.
