Lexus ES300h 2017 lights flash 4x and doesn't start

Question

Using evo all and rfk942 on 2017 lexus es300h. hybrid, pts.
Installed using harness and connected white/black to purple wire on start/stop switch.

Programmed without issues, dcryptor ran fine. Able to lock/unlock using both OEM remote and rk942 remotes.
When trying to start (with either the oem or rk942) the parking lights and the red led on the evo all flash 4x.

Have tried:
a11 hood switch off, reset and reflashing, tested all connections. confirmed D4, D6 enabled.

Instructions say this means ignition before start. Not sure what is meant by this. The French translates to ignition key detected before starting? I have placed both OEM keys at a distance and tried the rk942 to start and got the same result.
