Mods are UR pulley set, MOtordyne Plenum 1/4 spacer, RSR Exhaust, JWT Pop-Charger

Had a hard time starting car last night, battery voltmeter showed at 11.5V (too low) I then Charged battery.
Slightly having a hard time to start but once started voltmeter measures at 12.5- 13V.

Don't have any OBDII tools/software nor any AutoZone here. Only place is the dealer (I think)

If for instance I bring my car to the dealer I know they'll say that due to my mods those may have caused it and can't do anything?
What can I do? Put everything back to stock first?
any advise

Thanks in advance

 

Hi Mike,

If you have black pullies, they probably won't be noticed. And with the plenum spacer, its stealth so they probably won't notice that either.
Having an exhaust probably won't be an issue, but you might want to switch out your Pop Charger before going in.

There is probably nothing wrong with the PC but it is pretty blingy.

 

Do you need a new battery? Does it hold a charge?

 

I started my car and then unplugged the negative terminal from the battery and car stayed on, so I'm guessing its not my alternator but the battery.
Tested the battery and only holding about 11.5V so, I'm going to get a new battery.

Would a battery cause the SES light? but why didn't the battery icon lit ?
We'll see how it goes.

 

Its hard to say what the problem could be without knowing more symptoms or the error code

 

Ok, battery was checked and it just read at 11.5V. Battery was replaced under warranty.
SES light was still on after replacing battery and drove around for 30 mins.
Brought it the dealer, they said that "Found DTC P0462 Fuel Level Sensor Circuit Low Voltage --Erased light not a hard code monitored ok.

Any idea or anyone who can explain more on this "DTC P0462 Fuel Level Sensor Circuit Low Voltage"???

 

Only thing I could think of is that your battery was running a low voltage, therefore caused a low voltage read for the fuel level sensor and it threw the SES light. If the light doesn't come back on, I'm betting thats probably what it was.

If it doesn't come back, that was probably the reason for the code.
