Engine kills after 2 seconds

Question

2015 Subaru Impreza - standard key. Bought rfk411 and programmed successfully. Remote starter starts the engine but it kills after 2 seconds.

Answer 1

Sounds like either the immobilizer isn't getting bypassed correctly or an error with the Ignition wire connections

Comments

It's a t-harness for the ignition connections so I assume that should be fine as i didnt do any wiring around the ignition, just plugging.

then you will need to double check your IMO connections.
