Engine stalls when I put it in drive.
It idles fine in park , no misfires but as soon as I put it in drive it dies. I am getting no codes. Seems like the column bypass has been done since the steering wheel doesn't lock. I was cleaning the engine bay today with a little bit of windex and then started having the stalling issues. Any help is appreciated.

Did you PULL the codes or were you just expecting them to pop up in the DIC?
Here's how to PULL them:
http://www.c5forum.com/ayc/dtcdic.php
OR
Post all the codes including the H or C or HC that follow each 5 character code.
The stalling sounds like the 2mph fuel shutoff related to the Column Lock. If so that is most commonly caused by a weak or bad battery or loose or corroded battery connections.

Are you certain you have all the codes written down correctly??
None of my references show either of these two codes you listed:
P1560
P1255
There is a C1255 and also a U1255. Perhaps you had one of these???
The P1120 and P1220 are throttle position sensor Ckt1 and Ckt2 issues. You will need to drive the car to see if these come back.
The Uxxxx codes are loss of communications codes. Could be left over from some previous issue?????? Or they may indicate a problem with grounds that need to be cleaned. If they return after driving the car they need to be addressed.
The erratic idle can be attributed to disconnecting the battery as that would cause the fuel trim tables to be lost and need to be relearned. ie the car needs to be driven under varying conditions to relearn the trims.
I suggest you repull the codes and double check what codes are actually there.

If the problem is with the Column Lock system, there should be one or more BCM codes set that will indicate that. that's why i suggested that you repull and post the codes.
Your car is an automatic and likely has had the GM Column Lock Recall Service done to it sometime since 2004 when the recall started.. The column on 1997 - 2000 automatics will NO LONGER have the column lock once the recall service is done to it. That DOES NOT mean that you cannot be subject to the column lock symptom of the 2mph fuel shutoff. In fact in my first post in this thread I mentioned that the symptoms sound like the 2mph fuel shutoff.
I'll explain more once we see the codes your car now has..

[QUOTE=8VETTE7;1584333412]OK C1255 is a TCS issue that can be addressed a bit later.
Am I correct in saying that you still have the 2mph fuel shutoff when you try to drive the car????
If so i have a couple of things that you can try to get past the 2mph fuel shutoff until you get and install the CLB or LMC5.
Please post back if the 2mph shutoff still is occurring.[/QUOTE
Yes, still a no go in drive .

The battery problem has likely fried one of 2 relays.
Your car is a 99 automatic and because you are experiencing the 2mph fuel shutoff the GM Column Lock Recall Service MUST have been done to the car. When the recall on an automatic is done a GM K Harness is installed in series between the lock motor and the connector that goes to the BCM. These have an excellent history of frying when the battery goes low. Here is a pic:
You have 2 choices at this point.
1) If you want to drive your car now, you have to remove the GM K Harness and plug the lock motor into the connector that goes to the BCM. I can give you specific directions on how to do this if that is your choice.
2) If you can wait for an LMC5 to be shipped to you you can ignore the fact that the K Harness is fried since the LMC5 gets installed at the BCM and does not require any of the factory wiring to the lock motor.
There is a 3rd option in your case since the car must have a custom tune to support your supercharger. If your tuner will do it for you, you can have the 2mph fuel shutoff speed set to a high number. Then the car will be driveable but you will have the error messages for "Pull Key..." and "Service Column Lock" still appearing in the DIC.
Your choice!!
PM back how you want to go forward. If you choose #2 it saves me the typing of the specifics to get the K harness out of the circuitry. It is NOT needed and causes more problems than it has ever prevented when the battery goes low. If you want #1, I am willing to type the procedure in a post for you.[/QUOTE]
First of all, thanks for all the help! You've have been great. I would appreciate it very much if you could post up the info for option # 1.Going with the tuner is out of the question since they closed shop for good. Just my luck .

I did exactly as you stated but still will not idle in drive . Pulled the current codes P1626H,C1225H,U1000,U1096h,U1064H, B0338HC,B0367H. Continue getting a service column message along with pull key wait 10 sec . Checked fuses and all are good.

Ok checked the relay with the key on to see if it would click . The relay is good. That only leaves the column lock motor. I will proceed to take off the top cover to get to the lock motor.

Wrap the lock motor solidly with the handle of a good sized screw driver.
This is the second lock motor that has hung up on forum members in the past few days that I have been working with:

Excellent reason to NOT delay in ordering a CLB or LMC5 so this doesn't happen again.

Is the carpet in the passenger foot well wet or damp??????
If you look at the aluminum can that the BCM board is in (passenger footwell to the left of the IP fuse box) do you see white oxidation stains or stains that may be from water that has been in contact with the aluminum???
You said you have a new battery in the car. Have you measured the voltage across the battery posts with a digital volt meter with the Neg battery cable disconnected?? What is the voltage???

The No Load voltage on the battery MUST be greater than 12.5 volts for the column lock electronics to function correctly.
Measure across the battery posts with a Digital Meter with the Neg battery cable disconnected. If the voltage is NOT greater than 12.5 charge the battery completely. A good battery at full charge will measure between 12.7 and 12.9 volts or more No Load.

I'm out of suggestions as to what to try.
I have to assume that you did all the steps and did them correctly. I might double check all the steps if it were me. If I were closer I'd offer to come over and have a go at it. But, Tucson isn't that close to Fabens ( 350 Miles)......
Your best bet may be to wait for the LMC5. It connects directly to the BCM and leaves all the factory and dealer done wiring alone. (actually disconnects most of that stuff at the BCM.)
No guarantee but it should correct the problem unless the issue is the BCM itself.

I'm screwed the LCM5 didn't cure my problem
I installed it and went back to make sure it was installed correctly but still no change . Still the column lock message and as soon as I put it in drive it stalls. 
Ok discovered fuse 23 had blown and did away with the column lock message but still won't move. I talked to Richard from complianceparts.com and he tells me that he doesn't believe it's a steering lock column issue.
