JPOR: YJ won't start

[Steveman11@xxxxxxx]

Hey everyone,
I sadly had to leave my 89 YJ (2.5L, 4 cyl) sitting in my garage for the past 
year as I went to college.  So I've come back now and not surpassingly, it 
wont start.  I found that the battery was dead so I've replaced that.  I've 
also changed the oil.  When I try to start it, it will turn over but it makes 
a loud high pitched squeal.  I can't figure out if its coming from the engine 
or the fan or belts.  Please help.  Thanks.
Steve
