Please Help ! Supra Won't Start After DME Bench Unlock

[ThelixB]

Hello Everyone,

Any help on this would be highly appreciated !

I've sent my DME to bench unlock for my 2020 Supra, after getting locked up by the dealership due to the recall update. After receiving my DME I plugged back all the DME cables in the right sequence but the call won't start. The starter motor runs but the engine won't start.
I've read the fault codes using my bootmod3 app and it shows failure in all the injectors, which indicates no fuel going to the engine. See the fault codes screenshots attached.

Does anyone know what it could be causing this ?

Did you unplug it and plug it back in? Easy troubleshooting step. I used compressed air to blow out the ecu and connectors when reconnecting to ensure solid contacts. Maybe try that, too.

Thank you. I unplugged and plugged it back in a few time to ensure it is properly connected. Everything with the connectors seems fine and secured in place.

Make sure the connectors are seated fully, it's easy to get one that's not fully clipped in and making poor contact

If everything is hooked up right then it's gotta be something with the unlock. I'm not sure what is all done with the unlock, but if you hooked everything up correctly then it's gotta be something with the dme.

Any update?

I have no idea how unlocks work, or any experience with tuning software, but I am curious as to how you have a #7 cylinder injector in a 6 cylinder engine.

Have you asked the person/company who unlocked it? What did they say? Or are they being non-responsive?
