OK guys ima try to explain the situation as simple as I can. Car is 05' performance with 28k miles

Problem started yesterday when I was trying to start the car. It made "slow ticking sound 1 sec apart then the car starts". Before that it never happen. I never have trouble starting my car ever-always 1 click and it runs. No problems in idle

After 5 attempts of starting the car. It only make 1 click and car shuts. I've tried using spare keys method. I have 3 nothing work. If I put my key in turn it on for lights it's all fine nothin dim. I can pump music nothing twitches.

Note *Recent installations:
19"BBS LMs
Pioneer Avh-3200 DVD bypass
Tein STechs on tokico blues.

Any guess?

Sorry if I made any mistakes or any clarification you might have please let me know. I typed all this from my iPhone.

Thank you for reading

 

Try checking the ground on the battery or change the battery all together. Lights maybe working but that doesnt mean the car will start. A batter can read 12 volts but it wont start anything without enough cranking amps.

 

Checked. Everything is connected. A mechanic is suggesting "relay?"

 

pull the starter and have it tested?

 

I had a mechanic over and checked it out. He said the problem might be the head unit. Or something is still on while the car is turned off. I could only think of the headunit.

The unit is bypass does that have to do anything? And it's. 2months old.
