Alright. So I have my swap in the car, and everything is wired up. I have power, the ECU has power, the fuel pump is priming, the motor will crank. But if I take out the coils and put the plug in the coil and put it on something and crank it, there's no spark. My diagram that I used to do the wiring told me to put the Black/Red wire (Coilpack relay wire) to pin #46. But that pin for the KA side of the plug is for the rear defroster. So...I put the coilpack relay wire with the Ignition wire. So obviously the coils would get power while the ignition is on. But still...nothing. I have both relays for the blue plugs of the SR harness as well. If anyone can help me that would be awesome. I really need to get this car done, and I don't have the money to send it to someone, nor do I want to give up when I'm this close.

Verify that you're getting power to the ignitor. Start at the ECU and work your way to the coil packs and see whats not getting power.

Check your ignitor as well. Theres a way to check it on the FSM

Where is the ignitor located?
