Have an 06 cobalt ss power on with key no crank, bypass clutch switch and jumped relay car starts and runs and drives. Turn off with key and try start with key no crank no click. Has new started and all fuses are good. Any ideas?
Knowing how it works is key , the ignition switch is a low voltage input to the BCM - body control module . When the BCM see's start input it sends a message over the serial data network to the PCM / ECM - engine computer . When the engine computer reads this message it will energize the crank relay sending B+ voltage to the S terminal on the starter solenoid ,there by cranking the engine . Taking to a qualified repair shop that has a factory or professional scan tool to read BCM DTC'S - diagnostic trouble codes is what you should do , before you cause more problems .
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.

PROGRAMMED A NEW KEY FOB FOR MY 2005 SILVERADO USING THE PROPER STEPS ACTS LIKE IT ACCEPTED THE NEW FOB BUT WILL ONLY LOCK AND WONT UNLOCK. WORKS FINE MANUALLY, NOW EVEN MY OLD ONE ISNT WORKING ??
What are the proper steps ?
Method 1 - No Tools Required, Program All Transmitters
Important: All transmitters which are to be recognized by the PDM must be programmed in a single programming sequence. When using this program method, all previously programmed transmitters will be erased upon the receipt of the programming signal from the first transmitter.
The order in which the transmitters are programmed will determine its numbering position within the PDM memory. The first transmitter programmed will be transmitter #1, and the second transmitter programmed will be transmitter #2. The number stamped on the transmitter case is for reference only; #2 can be programmed as #1, or vice versa. Additional unnumbered transmitters are also available.
Close all the vehicle doors.
Insert the ignition key into the ignition lock cylinder.
Press and hold the door unlock switch.
While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
Repeat the previous step to program up to 4 transmitters.
Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter programming mode.
Operate the transmitter functions in order to verify correct system operation.
