It sounds like you need a scan tool that will access all of the modules in your car. The traction and ABS codes will be stored in the ABS control module. As far as the miss, it should be in the ECU and accessible from any general scan tool.

Interior Lights Circuit Description By using a feature called inadvertent power control, the body control module (BCM) supplies power to all of the following components: • The courtesy lamps • The dome lamps • The rear view mirror reading lamps • The instrument panel compartment lamp • The rear compartment lamp The left front door ajar switch turns the interior lamps on through the BCM by grounding CKT 394. When the left front door is open, the switch is closed. This condition provides a ground and a door open input to the BCM. The BCM then grounds the following lamps through CKT 156 in order to turn the lamps on: • The courtesy lamps • The dome lamp • The rearview mirror lamps The right front door ajar switch and the rear door ajar switches turn the interior lamps on by grounding CKT 395 from the BCM. When the ignition key is removed from the lock cylinder, the interior lamps remain on for approximately 40 seconds. The BCM provides an interior lamps-on delay after a door is opened. The lamps remain on for approximately 40 seconds or until the ignition switch is turned to the ON position. The 40 second lamps-on delay reduces to 4 seconds if a door is opened within 2 minutes of the ignition switch being moved from the ON position. The interior lamps immediately turn off when the vehicle begins to move. The dome lamp OFF-DOOR-ON switch controls the dome lamp. When the switch is in the OFF position, the dome lamp remains off. When the switch is in the DOOR position, the dome lamp lights when a door is opened by the BCM grounding CKT 156. When the switch is in the ON position, ground is supplied through CKT 750. The rear view mirror reading lamps are controlled by the rear view mirror reading lamps switch or through CKT 156 from the BCM. Voltage is supplied at all times to the BCM through the INT LPS fuse. The BCM supplies voltage to the interior lamps through CKT 1732. Battery Run Down Protection When the ignition switch is in the OFF position, the BCM turns off the power to all of the interior lamps after 18-22 minutes. The BCM will reset the inadvertent power control relay output when one of the following actions is performed: • Open or close a door. • Turn the ignition switch to the ON position. • Turn off any interior lamps that may be on. • Press the power door lock switch/keyfob button. • Press the decklid release keyfob button.

Have you bled the power steering? Jack up front so both front wheels are off the ground. start and warm up turn wheel from stop to stop slow until squeak stops make sure you keep filling it as you go. This may take a lot of turns. Let me know if this helps Mike

not working on dim ???? Low beams ?

FUSE IS PROBLEM CHECK IT

The service engine light does not affect the abs.You most likely have a broken wire in your abs system which is affected by suspension movement.A code reader which does abs codes will tell you which wheel circuit is turning on the abs light.When there is no abs available the track will turn off.

It could be the actual switch maybe???

i am pretty sure i know what the issue is i had i happen to me. the security system is failing its common in GM vehicles . i did a lot of research ad i found a module that you can install yourself that will bypass it and allow your car to start every time.. i did mine a few years ago and i have not had and issue since. they have great customer service and if fot some reason it doesnt work they will refund you %100.. Your car is on the It for this problem.. Check out the site ask questions .. it saved my car.. i hope this helps ya http://vatspasslockpasskeysecurityhelp.com/ Do It Yourself GM Security bypass

As far as heat, does the engine reach normal operating temp? Do the heater hoses get hot? Can you check circulation through the heater core? Check the actuator doors under the dash, see if properly operating?

How do you know that no fuel is getting to the engine ? Did you check fuel pressure with a fuel pressure gauge ? Did you check for spark at a plug wire ? What short did you have in the dash ? There are videos on youtube on trouble shooting a no start condition .Your instrument cluster is probably bad . You can get a new used one at the nearest auto salvage yard for $20.00 Also if security light is lit on the instrument cluster the vehicle won't start . The anti-theft system on these will disable fuel injectors .

Check fuel delivery. Filter may be clogged or pump may be bad.

Bad ground, blown fuse, incorrect jump starting.

dont put any thing in there

It may be called a "door check link".
