are you doing spark or timing a cam? what? what is JOB?
it dont matter, the engine, ecu does that, (magic)
but if it has a coil pack like my 3.8 then the coil pack must
be wire right and is marked. clearly on the pack.
they have USA jeeps and Export. country never stated here. sad huh?
and use differnent spark systems (3 types used, but 2 common)
per below.
v6.
is this not a Cheokee? the
non Grand ended in 2004. so...
ill go with GC 2005, v6 3.7L
the v6 began in 2005, not 2004, but, maybe yours is the first./
the 3.7 has coil over plug, spark, 6 coils.
and the harness is fixed to those coil so all firing order are
dictated in the ECU/PCM (hard coded)
VIN engine code, K. (not stated)

and already asked, and answered .
my 3.8 (2004) jeep.
is 1,2,3,4,5,6
and is like this.
mine uses wasted spark system.

so post VIN, or tell what engine is really there.
and the true year. or build date (sticker)
so my answer is.. 2005 GC, 3.7L V6, not I-6
it has 6 cops, "coil over plugs" 6 induction coils
and runs same firing order, as the old I6 did.
1-5-3-6-2-4
but the I6 4.0liter runs a coil pack and is quite different.
these;
times 6
all laced in, hard.
