NEED HELP 86' turbo wont start-code 12

[losingalltouch]

I recently finished swapping engines and can't get the car to start.

Here's the deal:

My subaru is an 86' GL-10 turbo. "New" engine i got is a japanese low-mile import. I had to strip everything off the block except the turbo to make everything work with the ecu. So yes, I took off the distributor and I think the timing could be one problem, although i was careful to not mess it up. The "new" engine is an AT and I have an MT so I swapped the flywheel and put in a new clutch. Hooked everything up after the swap and it wont start. Engine turns over, starter seems to be working, All spark plug wires are working, fuel injectors too so I checked the trouble codes. I got code 12, "starter switch off" and can't figure it out. Checked the wiring under the dash and all seems well. I'm still learning about electrical issues so the factory service manual is confusing me, but i THINK i figured out that it's talking about the wire running from the "key switch" (ignition?) to the ECU. Looks fine. I'm going to try putting new gas in the car as the gas that's in it now is about 5 months old. Hopefully that's the problem cause I just don't get why it's not starting (spark+fuel+air= boom, right?). After that I'll check the timing, but if anyone has experience with this trouble code I would appreciate your input. Just seems like the car should still start despite this.

Thanks

Part of the ignition circuit is a wire from the ign to the starter.

Its just one wire that hooks up to the starter solenoid, make sure it connected. If it is, you may have the disty timing off.

Hey, thanks again turbone (you helped me out a lot with engine swap questions before, all went quite well until now)

I'll check it out. Would the engine still turn over if that wire is disconnected?

[Turbone]

Yes it would.

Are you 100% sure you installed the distributor correctly? One tooth off is enough for the engine not to run.
