I would just about bet a weak fuel pump. With a scan tool connected you can monitor your fuel pressure thru live data. Low fuel pressure will not set a check engine light except if the O2 sensors register a lean condition.
Hdlyles2 Better to make your own Post rather than tagging it in the Additional Information section of an 11 year old post. That section if for Experts asking the OP for further information before committing to an answer, because an answer marks it as solved. https://www.google.com/search?q=air+bag+module+on+a+2004+Chevy+Malibu..
The simplest solution here is to have the ignition barrel replaced. There is so much electronics involved in a modern cars bypassing (hot wiring) the ignition can just cause more problems and usually expensive ones. The barrels themselves aren't that expensive and any good auto electrician should be able to fit and code the keys for it. Sadly it's the fitting that could be the expensive bit.
If back seats fold down like my 2003 Impala, you should be able to access trunk through back seat. There is an emergency release in the trunk to open trunk lid

Your better off finding the cause of the issue. Modern cars have so many sensors and electronics 'bypassing' electrics will become a Huge headache and put a massive dent in your bank account if it goes wrong!
Have you had the battery "Load Tested"? This is where they put a heavy voltage drain on it and see how it copes with it. How old is the battery? A battery can still hold 12 volt but be weak when it's got to supply power to high drain parts like the starter motor. Generally batteries are considered 'Old' when they are over 5 years old, especially on bigger and higher mileage engines.
The fuel pump relay should get power as soon as you turn the ignition to the second position so it can prime the fuel system before you start the engine. I've posted an answer to your Fuel pressure test question and in the video I've attached he shows you a quick "cheat" to test if it's the relay.
The first place to start would be to have a qualified repair shop hook up a factory or professional scan tool an check for DTC'S - diagnostic trouble codes stored in the BCM - body control module .
The body control module (BCM) performs multiple body control functions. The BCM can control devices directly connected to its outputs based on input information. The BCM evaluates this information and controls certain body control systems by commanding outputs on or off. The BCM control inputs can be:
• Sensors and switches that are directly connected to the BCM
• Class 2 serial data received from other control modules connected to the class 2 serial data link
The BCM is also capable of controlling other vehicle systems that are not directly wired to the BCM. The BCM does this by sending specific messages on the class 2 serial data link. The control module capable of performing the required function will respond to the BCM message.
The BCM controls these functions:
• Audible warnings--Refer to Audible Warnings Description and Operation in Instrument Panel, Gages and Console.
• Automatic door locks--Refer to Power Door Locks Description and Operation in Doors.
• Automatic headlamp control--Refer to Exterior Lighting Systems Description and Operation in Lighting Systems.
• Interior lighting--Refer to Interior Lighting Systems Description and Operation in Lighting Systems.
• Keyless entry (AUO option)--Refer to Keyless Entry System Description and Operation in Keyless Entry.
• Passlock theft deterrent--Refer to Vehicle Theft Deterrent (VTD) Description and Operation in Theft Deterrent.
• Retained accessory power (RAP)--Refer to Retained Accessory Power (RAP) Description and Operation .
Then if no DTC'S , pick one of the systems messing up . Test electrical circuit , using a wiring diagram an a DMM- digital multi-meter . Watch this video , not same model or make ,watch how this professional tech diagnose's
Chrysler Pacifica TIPM Electrical Problems
Question edited for clarity.
Question moved to model category.
Resetting the airbag light on your Chevy Silverado should be easy to do. Follow this video to watch it being done in a Chevy Silverado. To start with, you will:
Put the key into the ignition
Turn the key to the "on" position
Wait for the airbag light to turn on
Wait to continue until the airbag light turns off (around seven seconds)
Repeat the same steps twice more
Turn on your engine
After you take these steps, your airbag light should turn off. If it doesn't do so, then you should consider taking your vehicle in for diagnostic testing.
If the airbag light remains on, it could mean that something in the system is faulty. That could mean the airbag, the computer wiring, or another issue. Oftentimes, when the airbag light comes on unexpectedly, it is because of interference with the switch.

The fuel filter is positioned in the line leading from the gas tank to the engine and prevents containments from getting inside the engine, which could lead to a loss in performance and potential damage to the cylinder lining.
It may be because of a bad fuse, so first replace the 20-Amp fuse located in the instrument panel fuse box. If that does not solve the problem, check for:
1. Broken switch connection
2. Broken switch
3. Broken or weak wiring
4. Broken circuit
5. Faulty heating pad
If this sounds too overwhelming, it would be best to take your car to the dealership for a quick fix.
