so ive finally completed my h23a vtec swap in my 02 accord so i tried to start it and all it does is crank i used the pcb ecu first and it wouldn't even run the fuel pump so then i swapped for f23 ecu(poa) and it made a little more of an attempt to start but still no life but this time you can hear the fuel pump and i have spark but i dont know if the injectors are even pulseing or if my spark plug wires are right also i plugged up my scan tool and it read both ecus just fine the poa threw a check engine where as the pcb did not does anyone know where to start with this problem?

 

What have you trouble shot your self?
When you did the swap did you follow some one else's DIY?

There might be some differences in sensors/locations and wiring.

Usually the ground that goes to the t-stat housing is the culprit but I don't know if you've checked that already. Let us know how it goes.

 

what I did with the pcb ecu is switched the fuel pump wire from iirc a15 to a16

Ok so ive looked at my firing order and im all good there now i had the wires on upside down causing the no start, so I tried the wire swap on the ecu and it starts and runs now on the pcb ecu now I have two issues still 1. my check engine is on and so I'm in limp mode now. The code is p1166 o2 sensor bank 2 sensor 1 heater malfunction something like that is there any way to get rid of this or do I have to live with it I'm obd2b pcb ecu etc
2. Temp gauge doesn't work at all
Any suggestions for these problems?
