Hard Starting On My 2012 Corolla by minista94(op): 1:49pm On Sep 02, 2025
Good afternoon all

My 2012 corolla i got few days ago is just doing hard starting,

On Saturday when I went to pick up the car, it wasn't doing same, upon we off it severally, even at the filling station too when we branched to fuel it, it started at one attempt.

The issue started when I got home, I packed at the gate to open the gate, I switched off the car when i wanted to open the gate though, as I opened and entered my car to drive in, I tried starting it, it could not start again o, I tried and tried and it's still same, I waited for about 10 minutes and tried again and it started. I drove in and switched it off, tried starting again and it couldn't start.

The follow day, still same, yesterday being Monday, still the same thing.

People were say is because i removed the battery of the car, that's why it's behaving that way.. YES i got a new battery and removed the old one before coming back home that first day.

Please is there anything i can do to resolve this? I'm even scared to switch it off while on the road because it might misbehave again and all these Lagos agbero fit rush me..

Kindly advise

Bad spark plugs
Bad couls
Failing fuel pump
Bad or going bad car battery clamp or clip.

When removing battery remove the negative first .
When putting it back. But the negative last.

Do you have a car scanner?
You can scan to see if they'll be codes. Anything from bad kick starter to spark plugs to faulty fuel pump can cause the issue.

Your 2012 Corolla's hard starting issue could be due to several factors related to the battery replacement. Here are some potential causes and solutions:

*Possible Causes:*

- *Loose or Corroded Battery Terminals*: Ensure the terminals are clean and securely attached to the battery posts. Use a wire brush to scrub off corrosion and apply dielectric grease to prevent future issues.
- *Faulty Starter Motor*: The starter motor might be worn out or malfunctioning, causing intermittent starting problems. Consider having it tested or replaced if necessary.
- *Alternator Issues*: A malfunctioning alternator might not be recharging the battery properly. You can test the alternator's output with a multimeter or consult a mechanic.
- *Ignition Switch Problems*: A faulty ignition switch can prevent the car from starting consistently. Look for signs of wear or damage on the ignition switch.
- *Security System Activation*: Some cars have security systems that can prevent starting after battery disconnection. Check if your Corolla has such a system and if it needs to be reset.

*Troubleshooting Steps:*

- *Check Battery Connections*: Ensure the battery terminals are clean, secure, and free of corrosion.
- *Test the Alternator*: Use a multimeter to check the alternator's output voltage, which should be around 13.5V when the engine is running.
- *Scan for Error Codes*: Use an OBD-II scanner to check for any error codes related to the starting system.
- *Consult a Mechanic*: If you're unsure about diagnosing or fixing the issue, consider consulting a professional mechanic.

*Preventative Measures:*

- *Regular Maintenance*: Regularly check and maintain your car's battery, starter motor, and alternator to prevent starting issues.
- *Proper Battery Installation*: Ensure the new battery is properly installed and secured to prevent loose connections

I later found out it was the small black chip in the key that's causing the issue because it wasn't placed properly due to the bad key casing.

Yes the guy told me immediately he inserted the key and the security light still blinking, that's the new thing i learnt today o

Another thing is my AC compressor, I went to two places and they confirmed it's bad, but they told me to get manual compressor but I'm still skeptical...

Re: Hard Starting On My 2012 Corolla by minista94(op):
Why removing dashboard again for AC installation?

How much is auto? Is it toks or new one you're recommending?

Re: Hard Starting On My 2012 Corolla by minista94(op): 1:38pm On Sep 04, 2025
Mine is resolved, it's not plug nor coil,
It's the small black sensor in the key that's nor properly placed due to bad casing.
