I have a 07 G6 GT Coupe and my remote start hasn't worked since I've got the car. Everytime I try to use my remote start my lights start blinking and alarms go haywire. My remote start is turned on in the computer any sudgestions.

A lot of conditions will disable remote start. One of the most common is a bad hood ajar switch. But without access to a tech 2, all you can do is throw parts at it. I recommend spending the $100 on a dealer diagnosis. Then you can probably DIY the repair. You might get something from this:

Remote Vehicle Start Inoperative

Diagnostic Instructions
• Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.

• Review Strategy Based Diagnosis for an overview of the diagnostic approach.

• Diagnostic Procedure Instructions provides an overview of each diagnostic category.

Circuit/System Description
Remote vehicle start (RVS) begins as an RF message received by the remote control door lock receiver (RCDLR) from a keyless entry transmitter. The RVS request is sent by the RCDLR to the body control module (BCM) via serial data. The BCM monitors system conditions such as content theft deterrent (CTD), hood ajar status, and body DTCs to determine if an RVS even will occur. If conditions are determined to be acceptable, the RVS message is sent to the engine control module (ECM). The ECM monitors system conditions such as engine control parameters and vehicle theft deterrent (VTD) to determine if engine starting will be allowed. If conditions are acceptable, the ECM will initiate engine starting. During the engine run time in a RVS attempt, before the operator enters the vehicle, the ECM may discontinue engine operation if system conditions require it or a message is received from the BCM requesting the engine be turned OFF.

Diagnostic Aids
Important: If the vehicle has a current vehicle DTC that illuminates the malfunction indicator lamp (MIL), the cause of the DTC must be diagnosed before proceeding with the Remote Vehicle Start Inoperative diagnostic.

The RVS system will not operate if any of the following conditions are present:

• A current vehicle DTC that illuminates the malfunction indicator lamp (MIL)

• The vehicle is in valet mode.

• More than 2 remote starts have been attempted.

• The hazard switch is in the ON position.

• A current hazard switch DTC is set.

• The vehicle hood is ajar.

• A current hood ajar DTC is set.

• The CTD system detects an alarm trigger.

• Excessive engine RPM

• Excessive coolant temperature

• Accelerator pedal position greater than 0 percent

• Vehicle not in Park

• Vehicle theft deterrent malfunction

• A current automatic transmission shift lock control system DRC is set.

• A vehicle speed sensor signal is detected by the ECM.

Circuit/System Verification
Verify that RVS is enabled in the vehicle driver information center (DIC).
⇒ If RVS is not enabled, use the DIC to turn on RVS functionality.

Verify that the keyless entry functions operate with all available keyless entry transmitters.
⇒ If the keyless entry system does not function properly with all available transmitters, refer to Keyless Entry System Inoperative .

With a scan tool, verify that no RVS Disable History is present.
⇒ If RVS disable history is present, refer to the applicable subsection in which the failure occurred.

With a scan tool, verify that there are no Current CTD Triggers present.
⇒ If a CTD trigger exists, refer to Content Theft Deterrent (CTD) Alarm Mode Inoperative .
