Parking light fuse blows only when truck is running
or key on....running lights do not have a short
cause it does not blow the fuse with the truck off...
As soon as I turn key on it blows... I even started
my truck and then tried to put fuse in and it still
blew ....

Sounds like you have a chaffed wire supplying additional power from a 12 volt source once the key is turned to the on position. You can begin checking the wire run look for damaged wires. Or you can begin pulling fuses for other lights and devices and turning the key to the on position and see if the problem stops.
