I need to know how to test a 95 saab 900se v6 coil pack im having missfires on some cylinders and others are pulsing fast and some at a slower steady rate . I have seen this by using a timing light to the plug wires. (car acts like its running out of gas) I cannot find this info on the web thx paul

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.

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.?

Exchange cylinder 4 and 5 parts with 2 other cylinders and see if the problem goes to the other cylinders.Start with this first.

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

replace the coil

You need to change all of your wires, there may be one or two of them gone bad. "Check it at nite to see wich one is sparking fire from the wires"..

having a problem with my 1995 saab 95 when having the muffler change all of a sudden the casket and the value are blowed, those this happen offen, or is it related to the muffler that this can happen, please help me with this? Hperez

raise your hood the 3.1 engine. from front left ccylinders is 246 and the back left is 135. go to coil pack . as you look down at the coil pack .start from the left .523641. 5 goes to cylinder 5 .2 goes to cylinder2 .3goes to cylinder3 so on .the 523641 that where your wires from coil pack to that cylinder will go.
