I'm starting to think this doesn't have anything to do with the engine swap, but more with the battery being disconnected for a long time. When I disconnected the battery changing the Cam position Sensor before, it did something very similar, but would die after 3 secs.
I'm also thinking I may have done the relearn wrong. I started this process right after shutting the car off, without waiting at least 30 seconds. Below is the relearn procedure I followed. Do you think not waiting after shutting the car off and starting the procedure could have effected the process?
With a master vehicle key, turn ON the ignition, with the engine OFF.
Observe the security indicator. After approximately 10 minutes, the telltale(security light) will turn OFF.
Turn OFF the ignition, and wait 5 seconds.
Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
Important: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to RUN. You must turn the ignition OFF before attempting to start the vehicle.
With a master vehicle key, start the vehicle. The vehicle has now learned the key transponder information and/or the ECM has now learned the fuel continue password.
If additional keys are required to be learned:
Adding Keys
Important:
| • | To initiate, this procedure requires that a learned master key be available. |
| • | A total of 10 master keys or valet keys may be programmed to a single vehicle. |
| • | This procedure adds keys only. The procedure does not erase previously learned keys. |
| • | The keys to be learned must duplicate the mechanical cut of the current key. |
| • | If more than one valet key is to be learned, immediately precede each valet key with a learned master key. |
- With a previously learned master key, turn ON the ignition, with the engine OFF.
- Turn OFF the ignition and remove the key.
- Within 10 seconds insert the key to be learned. Turn ON the ignition with the engine OFF. The vehicle has now learned the new key
