How old are the batteries, they come stock with a 750CCA batteries i would put in nothing less than a 850CCA battery. The price of a new ficm around $1100 or you may have to repair yours for around $300 looking at it looks like it's good see what it reads after new ones are installed at startup if it drops below 45v get it fixed because it will kill your injectors.

I think it has the original motor crafts,

Ficm stays above 47.5 always but I don't trust it

If they are stock don't screw around get some new ones M-C, Interstate, Sears, I would not get Walmart one in my 97 went bad 3 years old with a 4 year warranty said it was good with one cell dead still check out at 750 CCA buy there stuff the battery was so hot it was smoking on there charger, never again. Now i have 850 CCA in both trucks, Motorcraft
