S13 sr20det won't start

[soggysock]

Hey guys I'm major stumped on this. I converted my s13 from ca18 to sr20 a few months ago.

I used a new wiring loom to do it all

but this morning it just wouldn't start. No power to the clock on the dash or to the apexi avcr and the radio the fuel pump didn't prime either when the key is turned. Central locking also didn't work.

I've checked the fuses in the engine bay the 2x 25a engine cont ones and I've checked the battery voltage which is 12.7v any ideas

Thanks
Craig

It started fine and ran fine last night

Big grey 75A breaker in engine bay fuse box.

I checked that one as well and it's intact

I've put the keys in the ignition and turned it to accessory 2 position and checked the engine bay. The bay fuse box isn't getting any power but there is power at the starter motor and alternator.

Still no fuel pump prime and no power to the dash, turbo timer and the avcr. I don't hear any relays clicking when I turn the key.

What else should I check

Check the 2 plugs on the battery terminal are properly plugged in.

Check for power on engine side of green breaker nearest fuses in engine bay, this is the ignition switch feed direct from battery (from plug above with one wire). If no power here fix the loom.

In the ACC position check for power at turn signal fuse in drivers kick space.

In the ON position check for power at front end of fuel pump fuse.

If no power on those remove the steering column trim, unplug the IGN switch and do continuity tests. IGN is just screwed on back of steering lock so is easy to replace.

There was no power getting to the engine bay fuse box. The battery has been located to the boot. So what ever old wire was meant to do it isn't anymore. It ran a fresh 12v wire to the fuse box and all is good now as a temporary measure till i can find it
