I am having some problems with my 30A fuse #30 on my 1998 F150 2wd V6. It seems to blow every time I replace it and crank the truck. It says it controls the Radio Noise Capacitor, Ignition Coil & PCM Power Diode. My truck is stuck in my driveway out in the country...no way to get it to a mech shop...trying to fix it myself. Any ideas as to what would cause this to keep blowing? Has my PCM gone bad?
