Wiring of coil packs

NO YEAR told for a CHALLENGE? year 2000 to 2022,wow !
NO COUNTRY TOLD.
check the FUSES FIRST !!!!!!!!!!!!!!!!!!
with 9 engines used, gas (petrol) , sure not diesel.
all are 4 cylinders and diff. sizes sure.
so he does not know his job , that it?
find one that does.? for sure.
we have no such car here in USA;
for a fact 22 years made the spark systems are NO THE SAME
not old how may coil (HV) packs there are
1 pack (distributor ) year 2000?
2 packs, called wasted spark and 2 or 4 HV spark wires
4in1 pack bricks. one giant pack with 2 coils inside wasted spark.
4 packs called COPS, coil over plugs (sparks)
there you go 22 years of evolution of spark (and more powerful)_
my guess it is 2pack car, (or 4 pack brick)
in both cases, 2 /4 , the young kids working or boomers will not know what wasted spark does. and wired it all up backward
1>4 3>2 (ecu firing order is 1,3,4,2 for ever fixed)
Wasted spark fires. TDC
example 1 fires real ,and 4 fires wasted. wasted means wasted fining on the exhaust stroke. ( and saves owning 2 extra coils)
the magic of just 2 coils wired in series.
but if 1 HV wire is open 2 sparks die, OOPS?
my 1975 honda CB750 had it so is not new ever, this tech
what matters most of all is moving the HV spark wires 1 by 1
never just throwing the wires there. guessing.
HV means the 20,000 volt high voltage wire set.
and last ( causes)_
Some are , even year 2000, had s fire wall igniter block that drives all coil packs and sure that can fail too.
later years the ignitor was moved to the COIL packs.(cops)
and last last, ECU bad to spark coil inputs.
new year told
no engine told
no country told
a hard row to hoe, or a tough nut to crack.

good luck finding real tech. how knows his craft and the evolution of it.(complex)

1,3,4,2, is firing order (is clue 1)
and using (no engine told gee) a quad or dual pack wasted spark coils, they fire 2 at once.
1 and 4 fire
then 3 in 2 files, at same time.
this tech is seen back to 1974 , save money for not having 2 more coils as seen all every new car now. called 4 COP coils;
the ecu cuts fuel if spark fails on all EFI made. (ASE class day2)
the causes are simple. in order of common.
1: the HV wire is bad, for sure carbon or the silicon jello junk wire core sets, pure OEM trash, I only use NGK MAG wires, or BOSCH MAG.
IF, 1 of the 2 spark plugs 1&4 are fouled so bad that act open, fails.
or 21 year old the spark gap is larger than hat rim, bad.
tech1 to tech 2, gee bob ,I can throw my hat thought that gap.
or coil pack bad. well try new plugs first the HV set wires.
or some dweeb swapped coil packs not doing 1 wire at a time
and mixed UP 1 from 3 wire, OOPS !.


the 2 paired spark plugs are wired in series
if one shorts the other works.
if one opens both go dead. Plugs or wires or driven coil)
just like old skool Christmas lites did for decades.

;post engine sizes? they used 3 engine, or more world wide
if it has a 4 wire pack the engine firing order is fixed by ecu
1342
but the COIL PACK must not be scrambled.
replace wires 1 by 1. (if new pack, mark old first)
if lost the org. pack is marked, 1,2,3,4 , if not you need
the marks, out of FSM or maker of new coil.
here is the list of engines, ;pick one>?

1.0 L G10 (LP2) I3
1.0 L G10T (LS3) turbo I3
1.3 L G13A/BA (L72) 8V I4
1.3 L G13B/G13K 16V DOHC I4
1.5 L G15A 16V I4
1.6 L G16 16V I4

if you cant use alldata.com to see that.
or cant use suzuki pit stop plus for $4
then google for your engine. and pray.

i can guess, because i can see the 2 coils there. in pack
and they are in series like this
1 <><><><><><<4 (series wound) the plastic case telsl me. this.
2><><><><><<> 3.
or group 2
2><<><><3
1><><<>>4

see? so try 1 ontop, run ok
no
try 1 in group 2.
this is called wasted spark
1 and 4 fire together.
then 2 and 3 as one;
so if 1 is connected right and 2,
then 2 and 3 must work if 1 fires right, see?
as you can see only #1 maters. if you now the coil end to end wiring.


tell country and engine, and all this is 100x more easy.
but ive never ever had to look it up.
the coil packs are obvious wired a certain way.
all in 2 guesses.

Check the connection to your coil pack for a corded or broken wire going into the connector. The coil pack is where the plug wires come from. Ford has a pigtail kit to replace it if it is bad. Or the coil pack is bad. Top, driver side of engine.

Only 1 in 10,000 PCMs is defective.

replacing PCM is the last, why do that. which jeep,? wrangler? GC?
ECU is not bad and is almost always (GIGO) garbage in ,nets garbage out, now and for ever....
all most all errors are
1: input errors.
2: or bad output actuators or gee the engine it self.

now lets work
2302
ever see this>? or the FSM, the FSM book is way cheaper than any knee jerk ECU swap.. ouch.
http://engine-codes.com/p2302.html
out of FSM. actual
(F342) ASD OUTPUT CIRCUIT
(K19) COIL CONTROL 1 CIRCUIT OPEN
(K19) COIL CONTROL 1 CIRCUIT SHORTED TO GROUND
COIL
PCM (last ) never 1st ever....
so the coil pack is 4 pins and 3 coils, one one is hot key on.
the other 3 are 3 coils, coil 1 is bad,,
from a pure tech stand point its.
1: bad coil (open or shorted) bad wires, open or shorted or bad ECU.
we never condemn any ECU unless we do the simple lamp tests.
etc. case in point below.
here are the FSM steps, so easy to do.... (truncated, read your FSM)
1: coil 1 removed, connector.
key on is pin 2, 12v, if no fix that first. ( bad power distra. or fuse)
yes, 12v. so.
then, use a test lamp to pin 3 and ground
Pin 3 is COIL 1, !
crank car , does light flash? (any small 12v lamp works) 0.1 amps are less.
1: yes, flash PCM good, coil bad.
no?
test lamp tests continue....
2: stuck on lamp , wire is grounded out or bad PCM (pull PCM C2 conn, ? still tuck on?, yes, bad harness !
3: stuck lamp off? . this is harness wire cut or PCM bad.-
check continuity end to end on this wire. if good , bad ECU.
on a car with nice clean harnesses, no damage to conn?
its a bad coil.
the coil can in fact can be bench tested...
that to, is in the books.
(ohms tests, and make real spark) do so but do not exceed max dwell on the coil "smoke tested boom."( you need a pulse generator , or coil tester)
easy to make them .
there you go.... ECU last. for ever and ever.....

Hello and welcome to FixYa!

The problem can be on the ECU (engine control unit). If the ECU is faulty there can be no spark to the wires even the coil is new. You may try swapping the ECU first.
Hope this helps and thank you for using FixYa! Have a good one!

Hello, I will suggest you get these few tools before you with the replacement.
(1) Spark plug socket with rubber insert to hold plugs in place while inserting & removing.(2) 6inch extensions for your 3/8ths inch socket wrench,(1) Swivle Socket extension for your 3/8ths inch socket wrench.(1) 1/2inch socket for exhaust manifold screws. A little quantity of anti-sieze for the spark pluggs to be applied to the pluggs if they are proving difficult to get out.
Start with the 1st cylinder at the front of the engine on the passanger side.
STEP 1.
Twist & remove the spark plug boot from the existing plug.
STEP 2.
You have to use a very small flat edged screwdriver to open the clips that hold the plug wires together.
STEP 3.
Use a 6" extension & a 3" extension & your deep socket for the spark plug.
STEP 4.
Remove the first plug and replace the old plug with a new Bosch Platinum Plus 2 prong plug and use some anti-seize on the threads and tighten to the appropriate torque.
STEP 5.
Remove the old plug wire from the coil pack. It will be going to the 2nd coil pack (located to the rear of the first coil pack) and install the new plug wire in the coil pack.
STEP 6
Repeat steps 1-7 for plugs on 2 & 3.
STEP 7.
To remove Plug #4 which is the last plug on the passanger side,you have to remove the two (2) 1/2inch bolts that holds a bracket to the exhaust manifold. Make sure you spray the studs these bolts are on with some DW-40 or liquid wrench. The exhaust manifold studs might have a lot of rust & being difficult to turn nuts off without shearing off the stud. It has some sort of aluminum box ontop of this bracket with some sensor wires coming out of it, Slip the bracket off and simply lay it to the rear of the engine to provide better access to this last cylinder.

STEP 8.
Repeat steps 1-7 for plug #4 and then Remount bracket containing the aluminum box with sensor wires.

Upon completion of the passenger side,you now have to proceed to the driver side.
STEP 1. The first cylinder at the front of the engine the spark plug wire has a grey handle sticking up next to the A/C compressor. Using some pliers (needle nose plier) twist & pull this grey handle. The spark plug boot should pop out.

STEP 2.With the help of the small flat edged screw driver, unhook the spark plug wire clips that hold the wires together. There are 3 - One just after the 1st coil pack located at the front of the engine, another just on the other side of the valve cover and a small 2 clip located about 1/2 way back on the valve cover under the intake manifold.
STEP 3.Remove the spark plug wire from Cylinder #1 on the Drivers side
STEP 4.With the help of the small flat edged screw driver,press the 4 connection points on the grey handle that is attached to the wire,it will separate down the middle and allow you to remove the wire, Replace the wire with the new wire,you have to ensure you line up the rubber round plugs with the round holes in this grey handle & snap it back together with the new wire in place.

STEP 5.Hold the spark plug socket in your left hand down near the plug,feed a 6" inch extension below the A/C Compressor line (black pipe) and the A/C Compressor with your right hand and attach the spark plug socket into the extension.
STEP 6.Slip the socket onto the plug,afterwards,attach an additional 3 or 6 inch extension to the existing extension & attach your socket wrench.
STEP 7.Remove the plug & proceed to replace it with a Bosch Platinum plug & anti-seize on the threads. Feed the new Spark Plug wire over to the 1st coil pack & replace it on the coil pack.

Hi I have a 1995 C200 Auto Sedan chs WDB 2020202F241703, I think I have a problem in the ECU. Only runs on two cylinders, I have changed the core pack on the 1 & 4 cylinders but the problem persists. The other problem is I don't know where the ECU (engine computer ?) is can anyone help ?

you may have to get the new engine harners wires and pcm form the 94 model, that will sove your problem

Looking on your engine:
(Coil packs)
5-2 3-6 4-1
(Cylinders)
1 3 5
2 4 6
Your firing order (although irrelevant):
1-2-3-4-5-6
