I've been having trouble with my 95 LT 4.3.
I removed the battery to charge but after putting it back in, it's seemed to have lost it's ground.
It doesn't have power anywhere... NOTHING works. Could the problem be the starter or is there a fuse link that could be blown?

I've had some electrical issues before. I've replaced the computer (by dealer) a little over a year ago and that didnt solve the problem.
The fuel pump, coil module, crank position sensor and cam position sensor have all been replaced with no results.

I would just like to see if there's anything I'm missing before I spend any more $$$
Thanks for your help in advance.

 

You should verify that you are getting power at all of the major junction points (starter, fuse box, alternator). This does sound like it could possibly be the fusible link (in the positive battery cable), but if you check for voltage at the aforementioned locations, you should be able to narrow the cause down.

 

Start with the source. Did you have the battery load tested? Possable a shorted battery from overcharging. My OHC Firebird toasted a brand new battery over two months due to a bad voltage regulator.
