The code reader says that I need to replace the number 2 coil pack in my 2007 V6 Ford Fusion. I am looking for a diagram of the coil packs so I can be certain that I fix the right one. Thank you

No code EVER says REPLACE THIS. Replacing the part that's mentioned in the code is the biggest mistake DIYers make. You may have a code that has the work coil in it, but that doesn't always mean the coil is bad.

Unplug the coil pack spark plug wires and mark where they go for future reference, unplug the coil pack electrical connector and then remove the retaining screws that hold the coil pack to the engine. You never say engine type, V6 or 4Cyl.

Firing order jeep Cherokee 2004 3.7 l v6

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.

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.
but the I6 4.0liter runs a coil pack and is quite different.

times 6
all laced in, hard.

Right side coils replacement

if it is a V6 you need to take the intake manifold off. remove the wire to the coil pack and there is a bolt that holds it in place. remove the bolt and pop out the coil pack. you may need to use some needle nose pliers to pull out the coil pack's boot.

1994 buick century coil pack location

The three coil packs are on the top of the engine, (I assume this is the 3.1 V6?) here is a picture of the coil pack, but all you need to do is follow the spark plug wires back to the coil packs (there are 3 on the V6).

How many Coil Packs should I get if I was to replace them?

Your car could have a 4 cylinder or a v6. If your car is a early "94" it cold have a distributor on both engines. If it has a distributor, ether engine will only need one coil. BUT If your car has a coil pack not a distributor, it will need,, if a 4 cylinder,, 2 coils, if a v6 it will take 3 coils. .

Code p0316 also p0300 truck has no power

P0300 is a random misfire and P0316 is misfire at start-up.
If you have the V6, I would start by replacing the plugs and all the coils.
This is a little ******* the V6, since you have to remove the intake manifold, and the coils can be expensive. Coils are available on Ebay.
I've replaced all the coils on my 2002 Escape V6 after 100,000 miles. Typical V6 problem.

Generally, the issue could be the following from:

A code P0300 may mean that one or more of the following has happened:

  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor
  • Defective computer
