The secondary (high voltage) side of the ignition coil can be checked with an ohmmeter.
1. Label and disconnect spark plug wires from coil pack.
2. Connect an accurate ohmmeter between terminals 1 and 6 and take reading. Repeat for terminals 3 and 4 and for terminals 2 and 5.

Note the readings and compare the three


If no faults are found with the supply voltage, impulse signal, wiring, and resistance at coil, then the ignition coil pack should be replaced.

Will any Commodore v6 engine fit in a Saab 900se 2.5 v6 front wheel drive convertible or any other engine that you can get plenty of?


No you will need exactly the same engine as is in the car now.

Try putting anything else in the car and you will run into some very expensive problems.

2006 Suzuki forenza no fire from coil pack


what country? this is the WWW, post country for better answers.......!
Only a scope can see the fast 5mS signals to the coil.
so its either the coil pack or the ECU blown. (wires are always suspect)
you never said , all 4 are dead, or 1 or 2, and how many packs.
some non usa cars have wasted (2pak) spark , not 4 COPS.
state what cylinders have spark and which don't.
there are only 2 ways to fix cars.
1: guess and swap parts
2: use tools. my guess is you dont have them.
some coil packs are active (ignitor inside) others just a coil.
you can test the restance of the coils, with a DMM , ohm meter.
if active you cant.
the fsm covers this on all cars.

the 2006 Forenza as delivered to USA has.....
has a large single, dual wasted spark coil pack. (brick)
it does in fact have , internal ignitor drivers. inside. so can not be tested
with and ohm meter on the primary side. but can be on the secondary
you do know how to test wasted spark , right, All spark plugs must be
attached and grounded for the coil to work,
1and 4 are shared.
2 and 3 are shared.
so to test , you must keep the spark plugs (both or all 4 is best)
attached and the shells of spark plugs grounded.
there is a fuse that powers the coil pack. (usa)
the fuel pump relay sends power to the coil pack.
so of that is dead,so will be the pack. (im reading FSM as it type)
get an FSM.
pin 2 on coil pack is power. 12v.
pin 1,is spark 1&4 drive (fast ECU pulse)
pin 3 is 2&3 coil drive. (scope can see it)

recap, are you using the correct wasted spark testing method.
and are all 4 spark plugs dead.?

97 blazer is missing from take off at 1000rpm to 2000 then clears out code reader says o2 sencor and multable engine missfire


For the misfires, start by pulling your plugs. They either need to be cleaned or replaced if questionable. Then, you may have a bad coil or coil pack. You can test them with a multi-tester-you'll want resistance values that are specific for your vehicle. Alternatively, you can switch the coil packs around (if you know you have a good one from knowing which cylinders are misfiring and which are firing o.k.) If your misfires change cylinder numbers from swapping, you know you had a bad coil. Other possibilities for misfire could be the electronic ignition module or the pick-up coil inside the distributor(if you even have a distrib.)
FYI: code for o2 sensor means that circuit has a malfunction, may be the sensor itself, or a wiring problem. Good luck.

Im working on a ford ranger 2002 with the v6. i just need to see a pic of the piston order and the coil pack order. im getting codes for 4..5..6 missfire but im not sure witch ones they are


Cylinders 1,2 and 3 are the cylinders on the passenger side and cylinders 4,5 and 6 are the cylinders on the driver's side. They are numbered front to rear. The coil pack will have the cylinder numbers marked on the top of it. The actual firing order is 1-4-2-5-3-6
The top of your coil should look like this:
1 2 3
5 6 4

Your engine looks like this:
1 2 3
FRONT OF ENGINE
4 5 6
