Injectors may be dirty/leaking. Lift injectors with rail and turn on key to see if they leak.

No, it wasn't in your ABS system, ever. Your problem is a faulty fuel injector or possibly as much as a bad valve. These 2 things, one or the other, cause a dead cylinder. One of your cylinders is misfiring. Last # in a code will tell you which one is misfiring. If just an injector, check that is good or bad with an ohm meter on the injector pins with the harness off of it. If it shows a large difference between it and the other injectors, that's the bad one and needs replaced. If not an injector fault, do a compression test on all cylinders with ALL plugs out so it turns over freely. If one cylinder comes up low compression, you'll need a valve job done. Good luck friend, I hope it's just an injector.

There is a maxi-fuse under the hood for the headlights. Until you get the car fixed, just pull out that fuse when you shut off or don't need lights. It could be the Body Control Module (BCM) that is causing this. Without a multi-meter and a wiring diagram, you will be pretty much lost. One needs to start checking power in and power out on the appropriate wires. Like this: there will be a wire from the headlight switch to the bcm, then there will be a wire out from the module going to the lights or maybe to the dimmer switch, but it will be the power out wire. The BCM is under the dash, probably on the passenger side.

Sounds like a short in the circuit, which may or may not be in the steering wheel. It might be, if hitting the horn button actually stops it for a while. Be careful with the airbag and remove the fuse before messing with it- I've heard a slight short will set it off.

could be the internal shift solenoid of the transmission pan off to replace those TPS needs checking transmission computer module failing

Did you check out the ignition coil and associated wiring? You may have a weak coil or an intermittent/poor connection

very possible that the pump has failed (seized ) internally so get it checked out at an accredited power steering specialist shop if it does not produce pressure then the steering will lock or be extremely heavy to turn

Given the amount of electronic's on your vehicle , an control modules , have a full vehicle scan done . Not at a parts , thier diagnostic tool will not check BCM -body control module , Instrument cluster , air bag module codes . Your vehicle maybe have communication problem between modules . Suggest you google GM class 2 serial data communication network .

Check Power Distribution Center *PDC* located under hood in the upper driver corner, thers a relay box and fuse box.

Have the battery load tested, even if you think the battery is fully charged it may not be any good, believe me on this. Autozone and other auto parts stores do battery testing for free.

you can use easyout.if there is room to drill middle of the broken bolt easy out will help you out

you may have to run the motor as you bleed the brakes so the abs hydraulic unit can purge any air that might be caught within the unit itself.did you bench bleed the master cylinder before installing it on the car.this can save time and reduce the possible chance of air entering the system.make sure you don`t allow the master cylinder to run low on brake fluid.i also assume that you are bleeding the brakes properly.Left front brake works with Right rear brake and Right front brake works with Left rear brake.this is how the brakes should be bleed.

You have to do the basics first. Security light stay on? check for spark at the plugs and fuel pressure.

You may find the passenger fuse compartment by dropping the glove box or bending tabs that allow it to open beyond normal.
