H23A EK SWAP HELP!
Hey everyone im currently in the middle of an h23a ek swap. Using a p73 ecu and when key is turned the engine light wont come on and fuel pump wont prime or turn on at all. Anyone know whats going on? Any help is appreciated. Thanks

Ecu and fuel pump fuses are good and i tested the relay and it seems to be working. I tried my stock y7 ecu and that didn't change anything. It cranks and i have spark but still no engine light. And pretty sure they're just stock injectors.

Not 100% sure for an H23A, but I know on D and B engines there's a ground strap on the thermostat housing that's often left off by mistake during the swap. If that ground isn't present you'll get identical symptoms to what you're describing.

Correct me if I'm wrong, but doesn't the OBD2 p73 ECU have a immobilizer/transponder unit in it?
OBD-2 / Immobilizer Bypass | .: FF CHIPS :.
I would try a different ECU to see if that will crank the engine... preferably something OBD1 that requires a jumper harness.

The engine cranks and gets spark but no fuel.
i have tried 4 different ecus at this point including a p28 and im starting to think its something with the harness.

Hey man I know this doesn't help you but I'm wondering what axles you used because I'm doing an H23a swap in my ek as well and I'm in trouble. I ordered new axles from procivic.com I ordered an intermediate shaft and it didn't come with the carrier or carrier bearing am I able to buy that separate somewhere? Or do I have to buy a whole new half shaft? And if I do what is it because idk what to use now that I ran into this problem

I bought the yonaka swap axles and they work great.
