04 CTT won't start on first try occaisionally, no codes.

What causes this? Turn key and it sounds like a dead battery. Remove key and try again, works every time. No codes stored nor any warning lights. Idle is a bit grumbly for my tastes. 103kmi. Factory CPO until 100kmi. Sorta stumped and don't wanna start throwing parts at it.....

Have you checked the battery? Had it load tested? Also a chance the starter is beginning to fail..

Battery is brand new. 2500 mi on it. I'll test it but the starter was my guess. I also have clicking front axle CVs when it's cold here in Dallas. Temp goes up and clicking on tight/locked turns is minimal.

Is your vehicle equipped with two batteries? The optional second battery is used for starting and located in the spare tire carrier area.

I have been curious if I have the 2d battery, any idea what the option code is? My books are 100% complete and there's an option sticker on a booklet included.

Thanks Loren! Looking at my vehicle identification printout sticker on my service manual there are no 4 digit codes, only three digit codes. Maybe that is a dealer service sticker?

I had a very similar issue at around 135k miles and it turned out to be a primary fuel pump failure, took a while to diagnose. Loren can probably attest to the price, but it cost less than $400 for the pump.

On the stickers they just print the last 3 digits.

Can I test the primary somehow, fuel pressure perhaps at start?

I sent you a PM with your options list.

I do not see the second battery.
