#1 - Check the plug on the switch end. The connection is known to come loose, causing high resistene which can melt the wire.
#2 - Check for power with key on.
#3 - You're probably right.
#4 - I'd call it fixed.
#5 - Oily on the outside? This can definately kill a sensor.
#6 - Will need a new gasket if tightening doesn't stop the leak.
#7 & 8 - Clean off fluid and add leak detection dye to p/s fluid to determine exact source of leak. No sense in replacing the pump if it isn't leaking.
#9 - Oil pan, rear main or reside from leaking valve cover?
#10 - Front seal leaking behind balancer.
#11 - Could be a plenum pan but hard to say for sure without diagnosing as directed here - http://www.ramforumz.com/showthread....t=belly+gasket
