I have a 2006 cobalt all fuses are good new battery no codes show up when the ignition is turned over lights blink motor doesent turn over there is a light on the dash that has a car with a lock through it

A nice simple answer, you can't. Think of it this way, the car doesn't know you are the owner, and it is there to stop exactly what you are trying to do. You have two computer ECM and BCM, plus the antitheft module and a number of sensors all trying to stop you. All you have to do is the re-learn procedure. Plan B is an auto electrician or alarm / radio installer or auto locksmith.

30 Minute Re-Learn Procedure

1. Turn ON the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
4. Turn OFF the ignition, and wait 5 seconds .

If you installed a new ignition switch and now the security light is on than the BCM has not relearned the new ignition switch. You can google "gm security relearn" to find instructions on how to do this.

Some cars have inline fuses in the battery cables and have multiple connections for components making one get power and others not. If all your fuses are good, the next thing to look at is the electrical part of the key switch. Usually there is the mechanical part with the tumbler, and the electrical part.

Are you positive the battery is good? Did you try to jump it ? Make sure all cables are clean and tight. When you say "won't crank over" do you mean the engine doesn't turn at all? If not, I don't know why you think the fuel pump would be the culprit. If it cranks and doesn't start, I don't know why you replaced the starter.

Disconnecting the battery doesn't reset the light. You need a scan tool for that unless you get lucky and fix the problem and go through enough cycles for it to go out on it's own.

Take it to Autozone or Advance or somewhere and have them read the codes. They do it for free for you. (They are hoping you will buy parts there) They can reset the light as well.

Hello! Do you hear a click when the key is turned?...If no click is heard either the ignition key, the Crank relay, the starter, or the battery are suspect...Having lights and radio does not mean the battery is capable of running a starter motor......Put a meter on the battery...should read 12.5 volts...Turn key...Does voltage drop to 8 or 9 volts? Bad battery...If all is well with battery and connections to it...Check the starter fuse # 33 in the under hood fuse/relay box...If the fuse is good that click you should hear is from the Crank Relay in that box...If all of the above is OK connect your meter to the Purple wire that is connected to the starter motor...When the key is turned 12 volts must be on that wire...If there is the starter motor is defective...So, #1...Do you hear a click when key is turned...That would point at a bad starter or weak battery...#2...If you do not hear a click bad fuse #33, bad Crank Relay, bad ignition switch...#3...If fuse is good Bad Crank Relay or Ignition switch; Crank Relay is a low cost item ($10)...Replace Relay...Stop there and send a comment as to results...Guru...saailer

Tests/Procedures: 1. Perform zero point calibration of the yaw rate sensor/deceleration sensor. Potential Causes: Deceleration Sensor Zero Point Calibration
Tech Tips: Code C1336 is for Deceleration sensor zero point calibration undone. To perform zero point calibration, have the steering wheel in the straight ahead position and have the vehicle on a level surface within an inclination of 1%. Turn the ignition switch OFF. Use a jumper wire and connect terminals TS and CG of Data Link Connector (DLC) 3. Turn the ignition switch ON. Keep the vehicle stationary on a level surface for 2 seconds or more and verify that the VSC warning light blinks. Diagnostic Codes: C1336

Rough idle, flashing CEL, low power would indicate a faulty ignition coil. A armchair diagnosis would be to replace the ignition coil. You'll have to swap the the contact stems (rubber conductors between the coils and the spark plugs) and the igniter module.

Simple task requiring a 10 mm socket and ratchet, a 10mm box end wrench, a T-15 torx bit with adapter and a new coil pack. Cost around $100 and takes a half-hour.

TRY REPROGRAM KEY .PUT KEY IN IGNITION SWITCH TURN IGNITION SWITCH ON POSITION 20 SECONDS DONT START ENGINE WAIT 20 SECONDS TURN OFF SWITCH THEN TURN SWITCH BACK ON 20 SECONDS WATCH THE THEFT SECURITY LIGHT BLINKING.WHEN THEFT STOP BLINKING VECHICLE WILL CRANK.IF LIGHT STILL BLINKING.TRY FEW MORE TIMES KEY IN SWITCH ON POSITION FOR 20 SECONDS.MAKE SURE YOU HAVE THE CORRECT CAR KEYS IN SWITCH IF NOT WRONG SET OF CAR KEYS WILL SET OFF THEFT SECURITY SYSTEM.IF KEY RESETTING TRICK DONT WORK.CHECK BATTERY POWER MAKE SURE YOUR BATTERY HAS 12.5 VOLTS AND CHECK SECURITY THEFT FUSE.IF ALL LOOKS GOOD YOUR SECURITY HAS TO BE CHECKED OUT AT THE DEALERSHIP.

engine light came on once before plugs changed went away now back on steady this time not blinking has loss of power with pedal to floorboard then comes in but when comea to a stop idles like going to die

If you know anyone that has a portable booster, you should be able to plug the cord from the 12v outlet on the booster into the 12v (cigarette lighter or accessory charger) in the car, and get enough power to pop the trunk.
