When you press the CASE button, you then have to increase engine RPM to above 4000 (you have a 10 second window in which to do this), at the right RPM engine will stumble sharply for a moment, you have to immediately release throttle and let engine spin down to idle... then turn off key and wait at least 15 seconds.
Is this engine is a production car/truck or in a retrofit?
