2008 Chevrolet Cobalt LS - Answered Questions & Fixed issues
Rcdlr
If out of warrantee I would contact or take to a regular mechanic these dealers are as bad as bad gets.
Get a second opinion then go from there.

How can I get key out which is stuck in ignition of 2008 cobalt. It also won't start
This can happen if the battery is low / dead. To solve, connect a set of jumper cables between the battery in the Cobalt and a running car's battery. Shut off the running car. In the Cobalt, make sure all accessories (lights, radio, fan, etc.) are off. Step on the brake, then move the gear shifter fully into the PARK position. Next, either attempt to start the engine, or turn the key to the OFF position and remove it from the ignition. I hope this helps & good luck!
CAR WONT START
This may be due to the security system failing. It is very common on GM vehicles and hard to diagnose without the security light coming on to let you know. Look at this website, may help you out http://vatspasslockpasskeysecurityhelp.yolasite.com/
Clicks but wont turn over
Sounds like the battery may be dead and it could also be that the terminals may need cleaned or tightend
How do i remove 2008
- Raise and support the vehicle.
- Place a drain pan under the oil pan drain plug.
- Remove the oil pan drain plug.
- Drain the engine oil.
- Remove the engine belt
- Remove the lower AC compressor bolt.Remove the 4 oil pan to transaxle bolts (1).
- Remove the oil pan bolts.
2007 2.2l. Why is it stuck in Drive?
Sounds like electrical problem. Is the electrical connector properly connected to the valve body on the transmission ?
Maybe a solenoid was accidently unplugged when you had the cover off.
2006 LS. Where is harness to connect camshaft position sensor?
You really need to invest in manuals for these vehicles you're working on. I don't think this engine has a camshaft position sensor, regardless of the diagram you posted. Does the engine run? Is there a connector there to rewire? Is there a port/opening to insert a camshaft position sensor into? General Motors used the 2.2L and 2.4L ecotec engines in several models from 2002 to 2006 (or later) that had no camshaft position sensors.
Hi i have a 2007 chevy colbalt when i turn the key to aux the the car starts and i can shut it off i can take the key rite out and the car will keep running
Could be bad ignition switch or some other type electrical problem . Knowing how this system works on your vehicle is the key . The ignition switch is a low voltage input to the BCM - body control module . Depending on key position the BCM knows what relays to energize and what messages to send over the GMLAN serial data net work , PCM - engine computer . Hooking up a factory or some other type professional scan tool to view ignition switch inputs to the BCM , an checking for BCM DTC'S - diagnostic trouble codes .
Circuit Description
Moving the ignition switch to the START position signals the body control module (BCM) through discrete inputs from the ignition transducer that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the engine control module (ECM)/powertrain control module (PCM) requesting engine start. The ECM/PCM receives a 12-volt signal from the park/neutral position (PNP) switch or clutch pedal start switch notifying that it is safe to start the engine. There is a splice on this circuit in the fuse block-underhood that supplies power for the starter relay coil. The starter relay coil control circuit is then grounded by the ECM/PCM closing the switch in the starter relay suppling 12 volts to the S-terminal of the starter. Ground is supplied through the engine block.
Plus you need to under stand what power modding is , because the BCM is the power mode master . This will sound funny to someone who does not know about automotive electronics .
Serial Data Gateway
The body control module (BCM) in this vehicle functions as a translator between the High and Low speed GMLAN busses. The 2 communication protocols use the BCM to translate communicated serial data messages between the control modules over the 2 serial data busses.
Power Mode Master
This vehicles body control module (BCM) functions as the power mode master (PMM). Refer to Power Mode Description and Operation for a complete description of power mode functions.
Power to many of this vehicle's circuits are controlled by the module that is designated the power mode master (PMM). This vehicle's PMM is the body control module (BCM). The PMM controls which power mode (Run, Accessory, Crank, Retained Accessory Power, or Off) is active.
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle, the PMM is the body control module (BCM). The PMM receives 3 discrete ignition switch signals to differentiate which power mode will be sent over the Serial Data circuits. The 3-wire Ignition Switch table below illustrates the state of these inputs in correspondence to the ignition switch position:
Relay Controlled Power Mode
The body control module (BCM) uses the discrete ignition switch inputs Off/Run/Crank, Accessory, and ignition 1, to distinguish the correct power mode. The ignition 1 circuit is also routed to the Run/Crank relay for relay controlled power feeds during the appropriate power mode. The BCM, after determining the desired power mode, will activate the appropriate relays for that power mode.
