1996!!! DODGE RAM 1500 5.9L

Hi.  My name is Michael Stokes.  I work on
cars and trucks in my spare time want to
make a career of it..  I lean new things
everyday..  Love working on vehicles until it
becomes my own lol...  Here is my question.  
I have a 1996 Dodge Ram 1500 5.9L 2WD
extended cab.  I bought it from a lady it
belonged to her late husband that passed
away the truck sat for a couple years I
started it right up after charging the battery
for a few minutes.  Passed emissions got
her tagged and register been driving her for
about a year now started misfireing and
would shut off.  But start right back up.  Had
a code pop up when I got home it shut off
but started back up.  I went ahead and done
a oil change thin tried to chank her up she
wouldn't start checking the code found that
the Cam sensor AND OR crankshaft sensor
was bad.  I replaced the Cam senor and
rotor button code went away but still
wouldn't start.. So I replaced the crankshaft
position sensor still wouldn't start so I pulled
the new crankshaft sensor out and it was
broken already within 5 minutes of replacing
and trying to start her up..  Would it be that I
put it in wrong and it hit the flywheel??? Or
could my flywheel be broken and it caused
my new 100$ waist of a senior to break??  
Please I really need help have to fix my truck
only vehicle I have and have a baby on the
way need to get my wife back and forth to
the doctors and I need to get to work..  
PLEASE LET ME KNOW I AM OUT OF
OPTIONS AND DON'T HAVE THE MONEY
FOR A MECHANIC SHOP THAT SAYS THEY
CAN'T FIX IT AND THEY STILL CHARGED
ME 300 to tow the truck to there shop 200 to
look at it and alot extra that they claimed to
do...  And I had to pay 350 to tow it back
home.. I have spent over 1200 in a month
and could have gotten a new vehicle..  But
that's out of the questions now.  Please
someone help me I don't know what else to
do
