96 xj replaced cps wont start unless jumped

96 xj, burns out cps frequently. replace cps, still stumbling and throwing code p1391 code, so i replaced the cam shaft sensor/stator. Battery acted like it was dead, although when I jump it, it started up. However, it won't idle, but runs strong when revved up. Put in a known strong battery, still won't start unless jumped and won't idle. Any suggestions appreciated. Thanks in advance.

I'll check the battery voltage and test the alternator tomorrow. If the batter voltage is too low, and I know the battery is a good, what might that indicate?
