I don't know the exact year GM put in the Starter Relay check, but G1220 controls this, setting it to 'not used' will allow the engine to run with no starter relay load (resistor) on the ECM.....

G1220
Defines the type of starter relay fitted to the engine.
** WARNING ** DO NOT ALTER THIS SETTING ON A FACTORY VEHICLE, only change this setting for engine conversions.
And certainly NEVER set it to "Not Used" on a factory car, that setting should only be used on engine conversions when the starter relay is not controlled by the ECM.

Only the following values may be entered into this table:
- Apply to Ground
- Apply to 12V
- Not Used

Then

G1210
Selects the Anti Theft System used on the vehicle.
There is no defined VATS disable in this ECM, to disable VATS you must select either Type 2 or Type 3 from this list and apply the VATS patch to the operating system.

See Also: {B9903} "Disable VATS Patch"

Only the following values may be entered into this table:
- Type 1
- Type 2
- Type 3

And finally

B9903
Apply software update to disable the Vehicle Anti-Theft System.
After applying this patch you must perform a 'Full Flash' of the ECM.
