Swap issue: No starter trigger
 

So I am swapped.
Standalone to run engine, canbus is integrated.
I used the factory harness for everything else, but I get no starter when I turn the key.
Anybody have any ideas?

What are you using to trigger starter?

That is the thick white/blue wire used to trigger the starter. That is directly attached to the ignition switch (well sorta). You don't need to do anything other than plug it on to the starter solenoid.

If you are looking for "Switch Power" for you harness. You can use that grey wire to power a relay as the trigger wire.

Edit: Hoping this didn't come across as harsh, just not wanting you to hurt anything.

I am not sure what you are asking.
The entire body harness is bone stock, so the factory relays and stuff.

So factory Starter trigger wire then. White with blue tracer?

I have seen these write ups.
I intentionally left the stock harness intact to keep it looking factory and make the wiring easier.

Yup it's all factory.
Like I said all I have done is unplug the engine harness at the main connector.

Should just be able to use the factory trigger wire then. So thick white wire, blue tracer. Will be covered with the black plastic wire loom cover with grey electrical tape. Has a female spade connector on it if I am remembering correctly. Make sure clutch is down when starting as well

Yeah it doesn't trigger...

Manual or AT car?

Manual...
I am thinking some how the immobilizer is involved.

Base FRS Right? Can't tell from your instagram lol. Don't think Base FRS had an immobilizer

Wiring Schematic

Page 86 has the starter system wiring. Triple check everything there. Really weird.

If you don't have the factory ECU hooked up, it won't work either.

Yeah it's a base 2013

I have the factory ecu but not the injector driver that was on the engine.

Injector driver shouldn't matter

I have power out of the clutch switch....
I have checked everything I can think of.

You need to connect that white/blue wire directly to starter to trigger it, that's what Dustin is saying. That means you need to de-pin/splice that white blue cable and run it directly to your starter (please correct me if wrong @DustinS)


What standalone are you using?

Splice into the white/blue wire.. worked for me.

I messaged him yesterday. ECM wasn't sending signal through. By-Passed the ECM and it cranked over.

I'm interested in what is causing the ECM not to pass the signal. I didn't have to touch mine at all and it worked. Glad he it it though.

Request how you bypassed the ecm? Been working for many days and cannot figure this out.

I'm going to be starting an ls 1 swap this month. The car was originally an automatic (another reason for the swap). Going to a manual T56. Will I need to switch to a manual ecu?

I got my starter working simply by using a jumper wire in the fuse box. Really easy solution, no splicing required. No safety switch though, turn the key and the starter cranks regardless of ECU or clutch state.
If anyone wants to know about this solution I can post a photo, I did it two years ago so I can't remember which ones I jumped without looking at it.
Basically you just bypass the relay that the ECU uses (pull it out and jump two pins) so the key switch is directly connected to the starter.

Yes please sir, I'm hoping this should work for an auto ecu as well.

Perfect picture! May the car gods bless you with a never ending tank of gas.

can someone please explain how to do this im having this issue with a stock fa20 in a brz?

Your issue won't be anything like the original post... I would start a new topic, not in the engine swap section.

He already did.
