Crankshaft position sensor question
I have a 96 Chevy Caprice 4.3 V8 and I was wondering if I would have to do a crankshaft position sensor relearn when I replace the crankshaft position sensor...

You maybe need to look for "the codes behind the codes".
At least in the LS1 family, CKP relearn is inhibited by quite
a few other DTCs. It's also pretty difficult to do the forced learn
(I had maybe 1 in 10 success rate when I was tuning), the
sequence was pretty fussy).
Crank relearn should sort itself in the drive cycle and only
some other problem, or a driving routine that doesn't hit
all the criteria, should make the forced relearn necessary
(provided you're willing to wait).
