I just changed battered and also changed out positive battery cable as it was very corroded. When I tried to start it put truck in engine fail safe mode. It's a 5.4l with 93,000 miles. My assumption is new terminal was either not put in correct or not correct part. Any thoughts?

That wouldn't cause it.
If you mean it's in a "security mode," then possibly.
But you're not real clear on the details. Is it not starting? Or in "limp mode" where you have half power?

Is the check engine light on?
Do you have a code reader?
You could have maybe fried something in the computer.

Are you saying that you hooked the Positive cable to the Negative battery terminal? What your saying is all Greek to me.
