ECU not getting power CA18de to SR20det conversion

Recommended Posts

Hey guys, I recently had to reshell my S13 Silvia and my new shell was originally a CA18de, while my original was SR20de which I've now converted to turbo while reshelling. When I went to start it and after cranking for a bit, I noticed it didn't even sound like it wanted to start at all. So since the fuel pump was priming (although it doesn't anymore which is a mystery to me now since fuses seem good) I figured it wasn't getting spark, so I decided to test to see if it was getting spark but holding a coilpack with a sparkplug in it against a bolt on the engine while cranking the motor. After I saw no spark there I decided to crack the test light out and locate the issue. I started at the coilpack loom and quickly found myself at the ECU and realised it wasn't getting any power, which I then traced to the plugs where the passenger headlight is (which I rewired for the conversion according to what I found on the internet) and wasn't getting power to the ECU there either. I also noticed that the EGI relay is only getting power on 1 pin with the ignition on, where as the other relays in the fuse box get power at 2 pins. Is the EGI relay related to the ECU getting power? If so, where does the relay get it's power from? Or would it just be that I wired those plugs at the passenger headlight incorrectly? I just colour matched the wires as per what I read. Any help would be greatly appreciated because I can't figure this out for the life of me, among other electrical issues such as the cluster backlights not turning on, foglights not working, rear parkers/brakelights and only one headlight working, but those are all the least of my worries at the moment.
