Looking for firing and coil order 2004 hemi 5.7

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.

The 2012 5.7 Hemi firing order is:
• Coil...1-8-4-3-6-5-7-2
• Plug..6-5-7-2-1-8-4-3

yes, you will have 16 spark plugs. one plug goes to the wire going into the valve cover, and the other is under the coil. they are what is called a 'double fire' cylinder, and they naturally burn hotter.

STANDING FRONT OF VECHICLE CYLINDERS FACING YOU ARE 4 5 6 AND BACK CYLINDERS IS 1 2 3 NOW ON PIECE PAPER LOOKING AT IGNITION COIL PACK FACING YOU WRITE BACK NUMBERS 123 AND UNDER THAT NUMBER 1 2 3 WRITE FRONT NUMBERS 5 6 4 THATS YOUR COIL PACK PLUG WIRES LOCATION. LIKE I SAY 5 6 4 IS PLUGS WIRES LOCATION FACING YOU AND BACK NUMBERS 1 2 3 PLUG WIRES LOCATION ON COIL PACK. FIRING ORDER IS 1 4 2 5 3 6

The firing order is 1-3-7-2-6-5-4-8. Just to give you a heads up there is no coil pack. It a coil on plug design meaning each individual spark plug has a coil on it.

Here is the firing order diagram for that engine.

Several VIN engine there, check this diagrams...




Fig. 3.1L Engine Firing order: 1-2-3-4-5-6 Distributorless ignition system




Fig. 3.4L Engine Firing order: 1-2-3-4-5-6 Distributorless ignition system




Fig. 3.8L (VIN 1) Engine Firing order: 1-6-5-4-3-2 Distributorless ignition system




Fig. 3.8L (VIN K) Engine Firing order: 1-6-5-4-3-2 Distributorless ignition system




Fig. 3.4L Engine Firing order: 1-2-3-4-5-6 Distributorless ignition system

Hope helps (remember rated this).

The firing order is a sequence of ignition time when the engine cylinders deliver their power-strokes starting with the number-one cylinder. If this sequence is faulty or arranged disorderly, the engine may not start at all, and if it does start, it may does so hesitatingly, or not run enough well to enable it to drive-or simply lacks the power to move. A waste of gas, and unecessary tear and wear on the engine and its critical components ultimately result. Once the firing oder is correc and in proper sequence, the engine should starts easily and promtly, running as quietly as posiible.

For Dodge 2004 Durango firing-order:
All 6-cylinder K 3.7L MFI SOHC distributorless ignition:
1-6-5-4-3-2 (front 2-4-6) (back 1-3-5)

All 8-cylinder N 4.7L SFI (including HEMI 4-WD)
1-8-4-3-6-5-7-2 (front 2.4.6.8) (back 1.3.5.7)
(distributorless ignition)
It is also a good thing to try and compare the thread lenghts of the old spark-plugs being replaced with the new.
