Weird issue with my 13' Subaru BRZ
 

After adding an oil cooler here in China, there was a very weird issue with starting my car.

Issue:
I have to put my clutch pedal to the floor, hold "Stop Start" button about 30 seconds, then engines started.
Normally the car should start immediately when press the "Stop Start" button as all your cars, but now I should hold the button for 30 seconds every time like an idiot :(
Dose anybody know why this issue happened? I'd checked my ecu chip, the whole electronics system, the battery, the starter, etc, nothing wrong, all of them are OK. It kills me...everyday

HELLLLLLLP

does the engine crank while you're holding down the start button, or is there no reaction until 30 seconds later?

no reaction, nothing happened until 30 seconds later, crank and start

push your start button twice to turn the engine electronics on, wait a few seconds, then push in your clutch and push the start button again and see if it starts. maybe it might be a bad connection with your key fob or actual start button? what year is your car?

He mentioned in the title it's a 2013.


humfrz

i tried that, not work. start button checked, no issues.
the key fob, the key fob, maybe it was out of battery? i bought this car 2 years ago and lost the backup key fob.
Is there any thread about how to change the key fob battery? Thanks!!

Not sure about replacing the battery. But you can just hold the key up against the start button next time you try to start it. That's the secondary method of starting the car when your battery dies.

You've lost almost a foot off your car!

replaced a new battery, but the same issue. i went to the local dealer for help, they checked 3 days, nothing was found.

hmmm...very weird

I had this happen just a week ago. Dealer found out the immobilizer actually went bad on my 13 frs.

Thank you so much, Tomahawk, i will drive to SUBARU dealer to replace a new immobilizer. How much of a new immobilizer?

Well I had to get mine towed there since the immobilizer wouldn't pick up the key. It cost me $460
