Golf 4 1,6 doesn't have spark and the coil pack is new and well tested

Yes, the pickup coil is used to determine spark timing, so if pickup is bad, you will get no spark.

post 3, adds, no spark , 2/3 (and still no year, no country stated)
bad coil pack?
wired wrong, this pack.
no photo of the engine, nor real name of it, Petrol.
btw, we dont have "BAKKIE" here. not a single one.
nor KB trucks, either.
what spark system this car has, im clueless.
4 coils or 1 pack.? if one pack , replace all spark wires
if one pack system , if either 2/3 wire opens, both cylinders go dead. try new spark wires. high voltage,

or you measured spark wrong, on 1 pack car.
it takes 2 spark plugs do do that. 2 good plugs and 2 good wires,
#2 and #3, due to the fact they are wired, in SERIES.
see its called wasted spark system, with 1 coil pack and no distributor..
the testing is unique. on this, setup.
try new spark plugs, gapped correctly
and 4 new HV wires,
I bet its go. if not the coil pack is toasted.

Hi Delberta, The links below are short youtube videos showing how to fix a car that cranks but doesn't start, In the 1st video this guy tests if it's fuel or electrical.......................................................

I don't know if you have a cranksharft OR camsharft position sensor so here's both... I hope this helps...CHEERS.........................

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.?

Did you replace the coil pack or just verify 12 volt power to it? if both old and new coil packs have the same issue, (no spark on 2 and 6), then the harness to the coil pack has broken wires or bad connection(in the connector itself), or the computer is faulty. I believe each plug wire tower on the coil pack has it's own signal wire in the harness. Understand that the towers are "paired" together.
For example, cylinder layout.... 1 - 2 - 3
4 - 5 - 6
Depending on the firing order and the actual layout of your cylinder's the above layout would mean
1 and 4 get the signal to spark,(at the same time), even though 1 is on its power stroke, and 4 is on its exhaust stroke. Hope this is clear as mud!

Try switching your coil packs around see if you can get spark out of the 2 & 5 with a different coil pack in that location. If that doesn't work maybe your ICM they can test the ICM at autozone, but can't test the coil packs.

Hi, have you tried replacing the coil pack? This is a common fault on these vehicles.
Hope that helps Matt...

Usually the ignition controll module or pickup coil. Your local auto parts store should be able to test the module for you.

If you have a volt/ohm meter, you may want to first ohm check the resistance between the two spark plug towers on each ignition coil pack. Simply remove the spark plug wires from each coil pack and test. Both (if good) should test about the same resistance, (about 5-7 kOhms, but I don't have the exact specs handy on this particular vehicle. The reading may be higher, maybe around 7-12kOhms) but nonetheless, the reading of the 1-4 coil pack should closely match the 2-3 coil pack. If not, the new coil pack may be faulty and should be returned for a replacement.

Also, when you remove the 1-4 coil pack, take a look at the primary spade connectors (2 lugs) coming out of the ignition module. Make certain these are clean and free of rust or corrosion. If so, simply (and gently) use a finger nail file or 400 (or equivilent) sandpaper to file the corrosion off and re-attach the coil pack.

If one or both of these don't fix the problem, you may have to look at replacing the ignition module. But only do that after exhausting the other simpler and less expensive tests! :)

I hope these tips help you out or at least point you in the right direction! :)

CHECK FUSE.IF ALL GOOD COIL OR COILS IS GETTING POWER.THEN COIL HAS A OPEN IN IT.NOW IF COILS ARE GOOD AND YOU NOT GETTING SPARK.YOUR PROBLEM IS IN THE IGNITION POWER TRANSISTOR.OR ENGINE SPEED SENSOR.YOUR BEST BET LET THE VOLKSWAGEN DEALER TEST THE IGNITION SYSTEM.BECAUSE IF YOU SHORT THE POWER TRANSISTOR OUT.YOU ARE GOING BE OUT OF A LOT OF MONEY.BUT IF YOU GOT ONE COIL NOT FIRING REPLACE IT.IF STILL NO SPARK LET THE DEALERSHIP. CHECK IT OUT.
