How do i test a coil pack on a 2003 Saturn ION 2.2 L engine?

THE CARS VIN 8TH DIGIT TELL WHAT ENGINE IS THERE, so which one is it.?
check all fuses first, as in all (cab and bay boxes)
and battery must be charged and good first. and kept charged for this service and testing.
no spark on just one cylinder or all ,(no engine told of 2)???????
the service manual covers all that.

so starter does crank the engine fast?and robustly? not slow as slug.
1.9 L, SOHC, SINGLE CAM
1.9l DOHC TWIN CAM ENGINE
2.0l
3.0L ? V6?
THEY ARE not THE SAME AT ALL , FOR EFI OR SPARK
BUT Both engines run a pair of twin coil packs
rule1:
the 2 HV lugs on each pack both must be wired to the correct spark plug !!!

or firing order is noW dead wrong and fails. called wasted spark.

rule2
2nd rules is it those old 24 year old wires sets (junk) if one fails open, that makes 2 spark plugs go dead and bingo it will never start as 2 cylinder engine ever. never ever run 24 year wire sets, of fail you will !!!
go NGK mag-wire sets in fact. best.
rule 3: wasted spark
to test spark never pull 2 HV wires on one coil pack . test HV wires 1 by 1 using clean new test spark plug.
yes 2 can be tested at the same time but lets skip how now, do thme 1 at a time
spark tests. do not skip any.



scan the PCM yet for DTC errors, be big shame to miss out ,omg the PCM sees CMP or CKP dead. cam or crank sensors errors or coil pack errors.

Id have new spark wires installed this old. 24 years.
and now rule #4 wasted spark
do not pull off all wires to it replacing the pack
do so 1 wire off old pack on back on to the same exact lug. on new pack
or , firing order is lost.


for the 1.9L (wild guessing me the engine)
if you get it all messes up the cure is here
4 and 1 fire same time
2 and 3 fire same time, paired.

has water ran down your spark plug wire boots that stick straight up on the heads funneling water into spark plug hole ? this can cause it to not start ) pull the boots up and off several wires look to see if there wet if so dry the holes and wires with papaer towels and stick also is? spark coming from the coil packs check spark see if i jumps from the 2 coil packs check like 4 wires on each coil pack

did you check for voltage at the coil pack low tension input
this comes from the electronic ignition and the distributer dc setting on a multimeter

check inside the distributer that the little magnet is still in place on the rotor and that the sensor is outputing pulses as it turns over
{you can use a meter set to AC range for this ...}
pull a plug out and place its metal to ground check for actual sparks
if this is there then its fuel ...

check spark at the coil is ok .you need a spark plug tester.then remove the leads plug in the tester. turn the engine over are you getting a spark if no .check the distributor cap .clean the contacts,check the bush in the center is ok. check and clean your rotor arm..now check the plugs ,smell them if smell of fuel and no spark change them.

The spark and fuel system needs to be inspected.--------- The spark plugs are getting fouled or very loose, can cause sputtering problem.Inspect the spark plugs and coil packs.The spark plugs gets power from coil pack.If the spark plugs are very old and dirty, then it needs to be replaced.--------------- The **** problem also relates to faulty worn out spark plugs or clogged fuel filter or low fuel pressure or problem with ignition coil pack.----------- When coil pack stops giving power to spark plug the car will **** while driving.---------- So very first thing you get tested is spark plugs and ignition coil packs.If they are tested good, but looks very dirty/ worn out, that can also be the reason.----------- But if spark plugs and ignition coil tested ok and cleaned properly, but still same problem, then get fuel pressure tested.If fuel pressure is low, the fuel pump and fuel filter are the cause of problem.----------- ------------------ Also one more thing, " IS there check engine light coming ON dash" ? If yes, then get the car scanned at autozone service center.Its absolutely free to get car scanned at autozone.They do it for no charge.------- In scanning you will get error codes, as per error codes, it will point towards faulty part, causing this sputtering and jerking problem.----------------- But if there is no check engine light ion dash, then get the above mentioned possibilities checked.That will help.Thanks.Helpmech.

YOU HAVE TO REMOVE COIL PACK WITH PLUG BOOTS ATTACH TO COIL ASSEMBLY FROM TOP OF VALVE COVER.YOU HAVE 4 SCREWS ON CENTER TOP VALVE HOLDING COIL PLUG BOOTS ASSEMBLY IN PLACE. ONCE YOU REMOVE COIL PACK ASSEMBLY WITH PLUG BOOTS.THE SPARK PLUGS UNDER THE COIL ASSEMBLY.YOU CAN REMOVE SPARK PLUGS.FROM TOP VALVE COVER WHERE YOUR COIL PACK COME OUT.YOU NEED DEEP 6" INCH SPARK PLUG SOCKET AND EXTENSION TO LOOSEN AND REMOVE SPARK PLUGS. YOU NEED SPARK PLUG GAP GAUGE.YOU NEED TORQUE WRENCH.NOT MANDATORY LONG AS YOU DONT OVER TIGHTEN SPARK PLUGS.STRIP THREADS.IN HEADS

Drain all the oil and put on new clean, also repl the oil filter.
Your coil pack may also still be wet-- , mark your spark plug wires and the coils and remove them. Make sure the coils are dry the spark pulg wires ends are dry. Also the plug or the main harness to the coil pac may be wet still, pull the plug and dry that, use an old hair drier or just let it sit a day longer.

Probably coil pack. Follow spark plug wire from spark plug to where it plugs in, that is your coil pack.Some are seperatable. Depending on motor size you may have coil over plug. You said wires not (cop) coil over plug boots.If it is coil over plug it is just a boot you changed in that case the coils plug into boots & on plug & an electrical connector. They are seperate for each cylinder.

usually when it gets colder outside the car will misfire and run rough because the ignition module/coil pack goes bad and makes it misfire,youre gonna have to replace the coil and module,,its the black long piece that sits on top of the spark plugs,1 wire connector and 4 10mm bolts remove them and pull up hard to pop the plug boots off the spark plugs,then install the new parts and you should be ok

Cabin fileter behind glove box and plugs are under coil pack on top of engine.  Remove 4 10mm bolts and lift coil assm. Straight up.
