1. cruise control and traction control turned off

2. turned car off and tried turning on in hopes that traction control and cruise control would work since it would work in the past whenever they turned off

3. car wouldn't crank/start after i turned it off and i got
abs not working
cruise control not working
tire pressure sensor not working
srs not working (seat belt/airbag) all at once

4. Turned position off removed key and the lights on the inside would kinda flicker (head lights and dashlights)

5. after car is off i heard a clicking noise coming from the fuse box

6. looked up what could it be clicking on fuse box someone said relay starter fuse

7. i removed the relay starter fuse and clicking stopped

I'm going to replace the relay starter but hopefully this is it but why would a relay starter fuse even cause all of those other problems? Any one have an idea? Thanks.

Check the battery's voltage as well. Many of these signs indicate a weak battery. You have to replace it with a new one most likely.

Hi,
Here is some info on not cranking over this may not be helpful to you as mine from memory did not have the not working warning lights displayed just would not crank at all.

ECU goes berserk on low voltage and you get a plethora of false error messages. Rather than checking the battery voltage I bought a dual USB charger plus LED indication of voltage (cigarette lighter) from Aliexpress.
