No spark comming from coil packs

cars have many , control modules, most are microcomputer based.
the PCM on the Forenza runs the engine, EFI
spark and fuel and transmission shifting.
can be lots of things,
lost spark
check all fuse first, that means test them if they look good.
second, is use a scan tool to see why it dont start..(spark dead? and why)
there is no distributor on a 06. !
but there are 4 engines, used, not posting which engine, makes help near impossible.
most cars, 06, suzuki, usa , have a single coil pack
it has 4 coils inside ,one for each cylinder.
so are all 4 coils dead? is that it?
spark leaves the coil pack it never has sparking going it to it.
the coil if fired from the PCM
the PCM fires the coil with and ignitor.
the PCM fires the igniter if the CMP and CKP sensors work.

see coil pack below?
if all 4 are dead, we scan it after fuse checks. always....

Is the same cylinder causing the problem? If so take a close look at the spark plug for fuel fouling. The cylinder may be over fueled causing plug fouling. You may also have a bad coil or defective spark plug. Try swapping coil and plug with one from adjacent cylinder to see if misfire changes to that cylinder

the ignition coil pack assembly on the 2.7 liter Hyundai is known for going bad. it cost about $150 what is a shame is that i have a good one in my garage lol

it has 2 internal , wasted spark coils.
there is not one coil, but looks like 1 large pack but is really not.
it has 2 coils inside , 1 running 1and 4 and one running 2 and 3 spark plugs.
so are all 4 failing
and did you use the correct test, for wasted spark. in that
you must test 1 and 4 at once? and 2 and 3 at same time.
did you?
the fuel pump relay sends 12v to power the coil pack.
so if that is dead, so will all spark all 4 sparkplugs.
repost stating if you have 1 or All spark dead.

What was wrong in first place?why you change this that.battery,connection,fuel filter,fuel pump,check oil,

if you had a broken wire this would cause arking which generats heat so could be short else ware
coil pack will be on same circuit as fuel pump so needs checking

hi there have just fixed a mates bike tonite who had a spark on only one plug so what i did was take out all the plugs and with a small file i gently cleaned all the plug tops is an easy enough job so cleaned them all checked for fowling ie black spark heads oily heads or maybe a strong smell of petrol from the plugs these can indicate a problem with the mix fuel oil ratio but when the guy i helped drove off with all the plugs cleaned his bike started fine idled fine and sounded lovely lol is an easy job and try this first before buying new plugs hope this helps

Any idea how long the bike sat without running? So assuming spark plugs weren't wet, it's likely not getting fuel. If it hasn't run for a year or so, you'll have to empty the fuel tank and drain the carbs. Try fresh gas and new spark plugs. Make sure the fuel tap is on and fuel is flowing into the carbs. Also be sure your choke is closing when you move the lever. Check to be certain kill switch is in the run position. Charge battery so you have good cranking power.

Bad coil pack.

When cleaning your engine, water/degreaser went down the spark plug ports. Try using a air compressor blow gun to remove the moisture from around the spark plugs and boots. The water was causing the engine to misfire on 3 cylinders at first and as the ports started to evaporate the moisture, the less misfiring was occuring. Dry thouroughly and hopefully coils do not have damage to them. Also check to make sure the boot is making good contact with the spark plug.
