plugs, etc, 1999 JGC
Hi All. A friend's jeep isn't starting so well, so I suggested she
change the plugs, wires, cap, and rotor. However it seems that there
is a coil on each plug. Does anyone know what the equivalent operation
on the 4.7 is? The Haynes manual is less than complete for the WJ.
Also, are there any special tools(besides a spark plug socket) for doing
this?
Thanks in advance.

Nothing you need to do, the parts that wear don't exist on that
model. Only thing you could replace are the spark plugs.
Poor starting is more likely fuel related than spark. Need to
check the fuel rail pressure, should be about 32psi with the
engine at idle and remain there for about 1/2 hour after turning
the ignition off.

Check for the correct plug listed at front of hood, should be
Champion numbers, RC12MCC4 or RC7PHCB4, gapped a .040" 5/8" socket:
