I was looking at the 2004 Ford Explorer fuse diagrams and I see that in the Power
Distribution Box in the engine compartment ( which is " live ) that fuse # 41 is a 15 amp
mini fuse for the ignition coil on the 4.0 liter V6 ( I'm not a mechanic / technician , it's
just something I noticed )
replacing coil springs, 2002 ford explorer
On a 2003 Explorer, there is no distributor or coil pack. Each spark plug has it's own coil pack as part of the spark plug boot.
Could be a bad ignition coil either traditional type or C.O.P. (Coil on Plug) type
I was looking at fordparts.com and it shows the same part number ( Motorcraft DGE - 446 ) for the six tower coil pack on a 1994 Ford Explorer 4.0 liter OHV engine as the 4.0 liter OHV or SOHC engines in a 1998 Ford Explorer , so apparently the answer is YES
On my ( 1995 ) Ford Explorer , # 19 is a 25 amp mini fuse for the ignition coil , PCM system
coil---3---4 pack--2---6 plug---1---5
coil----3---4 pack---2---6 plug----1---5
coil----3---4 pack---2---6 plug----1---5
Bad coil, wire, plug. Fouled plug, vacuum leak.
I'm not a mechanic / technician , but I remember reading about another fellows Ford Explorer that would not start after it was warmed up ( he had to wait for the engine to cool down ) and it turned out to be his coil pack
