A scan tool won't help. You've already located the problem - an apparent
short on the power source for several critical devices. The cam and crank
position sensors are what tells the ecm when to fire which coil. You need
to
find what's blowing the fuse. The likely place to start is to find C42 /
C142 (you don't say which engine), and open up the pins leaving it, and
look
at which device has the short on it's power supply lead. Use a meter, don't
keep putting fuses in it. You might also look at the resistance to ground
on
the downstream side of the fuse. Start disconnecting things like the TPS,
O2
sensors, etc., and see what makes the short go away.
