mini me and manual swap combo..now the car won't start

I picked up a 98 civic automatic for a great price with an extra y8 head with intake manifold. The manual swap is complete using the write up by Luster Kid on ht and mini me swap, the car turn but won't start. here's what i have done to test it so far:

1. I know that the starter works because i took it out and gave it power and it spins.
2. The distributor and coil are fine because I swap my distributor with my friends car and it both work.
3. I know it's not the battery or the fuses because I got a new battery and check all the fuses as well.
4. There are not check engine light when the key is on the on position. however the automatic gauge cluster is on parked.
5. I've tried to switch to a manual ex ecu P2P ecu to see if it help but there seems to be one connector extra on the Y7 engine wiring harness.
6. I took the plugs out to see if it sparks but it doesn't so it could be the problem but i don't know exactly what causing it not to spark.

keep in mine I'm using the y7 engine wiring harness so could it be that I'm missing something that y8 engine wiring harness has. please any help would be great.

Check all of your grounds.

Sounds like an ECU problem or grounding issue. Check to make sure all your grounds are secure (wire harness by the thermostat, tranny to the frame of the vehicle), and that you are using the proper ecu. Good luck!!!

As mentioned above^^ check those grounds and power to the ECU.
No CEL means no power to ECU.
OR a burnt bulb (unlikely)

well the car does turn over. i can hear the starter trying to start and the belts moving. I've replace all the ground wires on the car (three of them to be exact)
How can i check to make sure there's power to the ecu? thanx

Are you currently running the stock ecu that came out of the car???

Maybe you should try that. I realize your check engine light will come on but it should start.

i think it has something to do with connecting the two matching colour wires and disregarding the 3rd wire, can anyone confirm this?
