Power FC help

[Magical Trevor]

I just finished installing my Apexi PowerFC D-Jetro, I went to turn it on to make sure everything powered on, and nothing happened. I have no power to the commander, the fuel pump didn't prime and all my dash lights work.

I installed the stock ecu back in the car and the fuel pump primed perfectly and the engine cranked over. I've checked all my grounds to make sure they're properly secured. I modified the ecu wires for the IAT sensor per instructions of the PowerFC install manual. Other than that I haven't changed anything.

Am I missing anything? I can't even tell if the PFC is getting any power to it at all.

Make sure the two relays next to the ecu on the SR harness are there and good. My car had the same issue and I found that an SR harness has two relays, my car had one relay near the old ecu that you are supposed to disconnect and plug into the SR harness. I believe its the ECCS relay.

check the apexi website. iirc there is a first-time start -up procedure that you must go through before you can start the car.

Well inside the cabin we have a spot on the harness to the car that has two spots for two relays. We only have one relay. We plugged that in and still got nothing.

Switched the relay plugging it into the other one and still got nothing. Any ideas?

We also heard that the FC is picky with the power and that there is a back up power wire that needs to be connected to get the FC to work even tho the stock ECU might work without it. Does anybody got any advice on this aswell?

Ill try getting some pictures here...

OK so here are the two relays, but only one connector coming from the car:

Here is where we have it grounded, along with all the other grounds for the car:

We also have this little guy hiding back behind the carpet:

We've also heard of people having this issue bcause of the ECCS because the stock ECU can work with one power wire but the PFC needs two. WE've heard of a post where i guy jumped the power on the pins and his PFC powered up, but what pins are these? Any info would be great guys, thanks!

Ok so we got the ECCS power figured out, everything powers on. Now the problem is, we're not getting any spark to the coils. Any other power wires or something that we missed?
