95 Sunfire 2.2
I am not getting fire to #1 (presuming #1 is 1st cyl.at pulley side of motor) It is not the wire. Plug is good of course.Compression is good. I understand that there are two coils. I would presume that if one was not working then it would affect 2 cyls. I can't really see very clearly where I am putting the new wire, but it snaps into place securely. Has anyone else had this problem. Could a bad coil affect one cyl. ? Any help would be appreciated. Thankyou

Short answer, yes. A bad coil will not fire into the cylinder

But could a coil that would control two cylinders, not fire on one of them? I understand that there are two coils, presumeably controlling two cylinders each. Thatks

There is one coil per cylinder.
It is imperative that you install the right plug wires at the right location. A lot of people pull the wires off and forget which plug/coil they came off of.
Installing the wrong wire on the wrong plug will result in the plug wire not seating properly on the plug tower.
How did you determine that you had no spark?
If indeed there is no spark, you have to replace the coil pack, which is one assembly for all the wires, and can cost some money.

Aproximately how many miles are on these plugs & wires and are they OEM or aftermarket?
Reason I ask is I had a similar situation and I was sure my plugs and wires were good but they were not and had fairly low mileage on them and were aftermarket.
The problem went away after I replaced my plugs and wires with original equipment (GM).
I'm not saying this will fix but it's something to think about.

I have tried new wires, according to parts manual there is two coils only. Thanks To determine spark I removed one wire at a time while running. Then left that wire off to notice no diff in performance.

Okay, cylinders 1 & 4 are controlled by a coil pack, and 2&3 are controlled by another coil pack.
There are two coils per pack, 1 for each cylinder
replace 1&4 coil pack.

bad cyl
I dont agree with mark on how he says the coils work. If you can see the coil packs then you can see the numbers on the coil and and you can also look at where the wire connects to the coil pack pull off the affected spark plug wire and look at the tip of the coil tower that would and should be the silver tip if it is not nice and clean and silver clean it up and clean the plastic just below it once this is done try some dielectric grease see how it works could save u some money if this does not work replace the coil but just remember to renumber the coil coil pack for future reference

jchevguy- like it or not, thats how it works per Autozone
Please do this to determine if it's actually a coil. A basic multimeter can do the job.
Remove the ignition coil(s).
Using an ohmmeter, check the resistance between the primary terminals on the underside of the coil. The resistance should be 0.50-0.90 ohms.
Check the resistance between the secondary terminals. It should be 5000-10,000 ohms.
If the coil failed either test, replace the coil.
