I am lazy and don't want to look through 33 pages for the problems I am having. Sorry.
2006 Chevrolet Monte Carlo SS 5.3L V8
no modifications
First,
Displacement on Demand is not functioning. Currently stuck in 8-Cylinder mode (honestly, I can deal with that as long as there are no bad things that will happen to it if it runs like that). Too much information to sift through and I am not techie enough to understand it.
Second,
Getting a P0521 error code (oil pressure sensor, gonna pay someone to fix that for me). Although it seems like my engine is going through oil at an not quite alarming rate. Definitely using more oil than my WS6 ever did.
Third,
Also getting a P1629 error. Theft Fuel Enable - incorrect/no signal. According to the information I have read, the car should not start at all, however, remote works and the key starts the car. Remote start does not. Tried reprogramming the remote and that didn't work either.
So any suggestions and/or ideas would be welcome.
Thanks for your input.

This is due to the check engine light, saftey feature

This is a common problem, under a hundred dollar sensor from your dealer. You can easily change it yourself.

P1629 is an indicator that the challenge response was not recieved within the 2 second requirement.This does not necessarly indicate a fault is present with the TDM or ECM. Factors such as a long engine crank, a delay in the serial data communication, or B-codes set in the TDM will cause P1629 to appear. This DTC should not be used as a fault indicator, but to assist in the diagnosis.
AGAIN the remote start will not function with the check engine light
So any suggestions and/or ideas would be welcome.

BUY an inTUNE or Trinity and turn off DOD/AFM
SEAFOAM the engine crankcase then change the oil and put new ngkTR6IX plugs in it, and clean your induction system.
