First I have a 2011 F150 EB with 5star tune


For approx. 2 months I have had a new optima battery. today my truck would not start, nor would it take a charge when attempting to jump from another car. When turning the key over, the dash lights up and just one click and all lights flicker and go off.


I tried another battery and was able to jump it to get home. when home same thing, wont start even when trying to jump. The funny thing is my multimeter says that the batteries have over 12v. I have had the charger on the battery for hours now and no start. With both batteries, the low battery indicators came on the dash.


any input would be greatly appreciated.

upon looking for error codes with my tuner, it showed an error of P068A


anyone know what that is?

Not sure what that error code is but other stuff sounds like a possible loose connection somewhere, starter, battery. ..
You may want to check the fuses also

I have had a similar issue but with no code.. Mine was just the battery terminal was loose.. I tightened it and all good... YMMV
good luck

Check the battery ground at the battery and chassis. Also check the engine block ground between it and the firewall.
