Could this be a stiction issue?

If so some rev-x or archoil should clear it up.
It could be part of the problem, but until you load test your batteries, and check your ficm, you may be wasting money on rev-x.

Sent from my phone that somebody didn't help me get.

Check you FICM first, that is free to do. Also, ditch that tuner.

sounds like stiction... are you running synthetic oil? I had a similar issue with rotella non synthetic, tried rev-x and it didnt help, next change i switched to the synthetic, thing starts great and is much quieter. might be worth a short switching if you haven't already

Dont waste your money on RevX yet...Altough it wouldnt hurt. Check your FICM voltage and batts, If those check out ok then put some RevX in it. Also switch to rotella T6 5W40 when you add your revx and stick with T6 5W40.

same thing yesterday for me

I actually had the exact same thing happen to me yesterday morning. My batteries were very low.....gave them a charge and she fired right up. I will be looking into DC Power Inc alternator for a near future swap. I just replaced the alternator about 7 months ago along with the batteries. I will probably also go with a nice set of Optima's to go along with the alternator.

I have a DC power spx300. I love it, but it took countless phone calls, email, and some very choice words to get it shipped to me.

I have read you need to upgrade the wires going with one of these alternators......did they include them with it?

Not sure what kind of oil you are running. But my suggestion....drain your oil, replace oil filter and refill with a good synthetic oil. Get 2 bottles of Rev-X and add to your oil when changed.

Dont get Optimas.. If you are not going to get a diehard or motorcraft just goto autozone and get there yellow batts. The yellows have a 3 year free replacment and prorated after that. Alot of people use the Reds also.. But NO OPTIMAS..

But I dont think the OP batts are just low, I bet he has FICM problems.
