Update. Same problem but now getting code 11 from 8 pin connector. I'll read codes from the 38 pin later.

I noticed the air pimp comes on when the car is started but will quickly cycle on/off for brief periods. Then the engine dies. How long should the air pump be engaged?

New codes: pin 4-7, pin 17-12, pin 19-11 which is consistent with the 9in code. All of these are TN or speed codes
