Default Crankshaft position sensor?????

Ok my problem is p0300 code, check for vacuum leaks with gague and was ok, checked intake for crack and gasket also with smoke machine it was ok also, check fuel pump with pressure gauge it was perfect, i noticed that on my scanner the crankshaft position sensor only had 14.0 v going to it could this be my misfire issue. accourding to the fuel trim it is running lean, there is no loss of power at all. Car is a 2002 firebird formula.

Its running lean and you have a p0300 code. FIND THE VACUUM LEAK!

FIND THE VACUUM LEAK, sorry there is no other way. Did you check the intake bolts? Or are you just assuming they are tight because you didn't find any leaks?
