It's like someone tried to ring them out like a wash rag. Instead of the pleats being straight they're twisted like a screw.

yes oem filters. I will check all the other stuff tomorrow. it has only done this twice. but it was running fine in-between all of this. I filled the secondary filter with anti-gel the first time it quit and it started like crap and cleared up and was running fine until Sunday

Welcome to FTE geneva1 
If you can give us a run down of mileage, previous work, past history, and any other info that may help. What do you use to read codes, are you getting fuel at the upper filter?

we here we go codes are po231, po611, po676 p2614 p2617. icp koeo is 1221 psi, icpv is 0.37, un pluged icp did not change anything. cranking engine over ficm is around 36v once you stop crankin it drops more. but before cranking is is at 48v. does that help any?

Anytime bud, this will be a good time for you to fully charge the batteries and to take them down and have them load tested separately ( completely disconnected from one another ), low system voltage is a FICM killer. It would also be a good idea to get yourself some gauges that read live data so you can keep an eye on things, scan gauge II or one of the smartphone apps like dashboss for IOS devices or torque pro for android or the Edge insight CTS is a nice unit.
