1. Faulty Passlock System: The most likely culprit in a 2001 Malibu is the Passlock system, GM's anti-theft system. This system uses a resistor in the ignition switch to communicate with the car's computer. If this resistor is failing, or the connection is bad, it can cause the described symptoms.
* Troubleshooting: Check all connections related to the ignition switch and the Passlock system. Look for corrosion, loose wires, or broken wires. This requires some electrical knowledge and potentially a wiring diagram for your specific Malibu model.
* Fixes:
* Clean connections: Carefully clean all connections with electrical contact cleaner.
* Replace ignition switch: A failing ignition switch is a common cause. This is often a relatively straightforward replacement, but requires mechanical skill.
* Passlock bypass module: As a last resort, a Passlock bypass module can be installed. This essentially disables the Passlock system, but increases the risk of theft. Only consider this if other options fail. A qualified mechanic should perform this installation.
2. Battery Issues (though less likely given the symptoms):
* Weak/failing battery: While the draining is a symptom, a weak battery can *exacerbate* the problem. A weak battery might not have enough power to initially overcome the Passlock system's resistance, leading to the long start-up time. Get the battery tested at an auto parts store. Replace if necessary.
* Faulty alternator: A failing alternator won't charge the battery properly, leading to the drain. Have the alternator tested as well.
3. Other Electrical Problems (less likely but possible):
* Faulty Body Control Module (BCM): The BCM controls many electrical functions, and a malfunction could interfere with the starting system and drain the battery. Diagnosis of a BCM problem requires specialized tools.
* Other parasitic drain: Something might be drawing power even when the car is off. A mechanic can perform a parasitic draw test to identify this.
Important Considerations:
* Safety First: Working with car electrical systems involves risks. If you're not comfortable working with electricity, take your car to a qualified mechanic.
* Professional Diagnosis: The best course of action is to have a mechanic diagnose the problem. They have the tools and experience to pinpoint the exact issue quickly and efficiently, saving you time and potentially money on parts you don't need.
* Specific Year and Trim: The exact location and configuration of the Passlock system can vary slightly depending on your Malibu's year and trim level. A repair manual specific to your vehicle would be extremely helpful.
Don't continue to attempt starts repeatedly. Each attempt further drains the battery, and could potentially damage the starter or other components. Get it diagnosed and repaired soon.
