It is not necessary to set the timing on a computer controlled engine. I think you mean to ask where the wires go. First, the motor is numbered down the left bank (that is standing in front of the car looking at the motor) 1 - 2 - 3, and the right bank is numbered 4 - 5 - 6. The coil pack is setting sideways and it numbers (left to right) 5 - 6 - 4 (front row) 1 - 2 - 3 (back row).

What should the spark plug gap be set to?


the spec is .043", for both the V6, and the Inline 4. The theory behind enlarging gaps, is that a larger gap creates a larger spark, thus more effecient ignition. The problem is, your ignition system was designed for the .043" spark plug gap, not larger. Enlarging the gap puts a greater strain on your ignition system components, and it may not be strong enough to jump a larger gap. The result would be less efficient combustion, or a cylinder(s) that won't fire at all. Pull your plugs, and set them at .043". Check the distributor cap, rotor, wires, and your filters. Make sure the car is totally warmed up before the smog test. Good luck.

1992 geo storm replaced distributer have fire out of coil wire but no fire spark plug wire module in distributer checks out


storm is an ISUZU
and had 3engines,which one? below is off wiki on storm.
1.6 L SOHC 4XE1 I4
1.6 L DOHC 4XE1 I4
1.8 L DOHC 4XF1 I4


coil makes 50,000 volts (even 1kv makes fire, but is too weak spark
spark plugs dead , right? all 4 right?
ever do a 60k mile tune up ? if not why not, it gets new spark parts then..
also, if the cam timing is off. the dizzy sparks between towers
make the distributor useless, it cant distribute spark.
so the first tests are .
static ignition timing. (yes, a tool, called a timing light for $20)
if timing is good the the wires HV are bad.
if timing is bad, bingo..... this is the first test on any motor.
if the timing belt or chain on any SOHC or DOHC engine slips
the dizzy will be way to h3ll off.
learn to use a timing light, and works 100% cranking.

look at that distributor cap (replace it)
see the coil wire , center, that is at 50kv spark.
and see that rotor, if the spark is good at the cap pins 1 to 4
then the dizzy is timed.
if the spark dont reach the spark plugs that means
the wire are bad or the spark plugs are shorted, or both.
its that simple. using a real spark testing tools tells you the KV.
kv = kilovolts. the best tools $5 bucks have and adjustable gap
this car is not 100kv, like newer cars and must be set (tool) to 50kv or tad less to show full powerful spark.

take care not to get shocked, keep hands off the parts
as friend cranks (or remote start button tool)

Replacing spark plugs


Not exactly sure what you need?
Standard Rules:
Use a Spark Plug Socket to remove and install Spark Plugs.
Replace (remove) one Wire at a time from one Spark Plug.
Replace One Spark Plug at a time. Use Anti-Seize Grease applied moderately to the threads on the new Spark Plug.
Using a Socket (with a extension) START all installations using your hands. This prevents cross-threading and stripping of the threads inside the Heads.
Standard Torque 15-20 ft-lbs.
Replace the One Wire connection to that One Spark Plug.
Replace that One Wire connection to the Ignition Coil.
Go onto the next Spark Plug using the above Rules.
Repeat.

For the 3.4L V6:
Firing Order:
1-2-3-4-5-6
Cylinders:
......(back)
1.......3.......5
2.......4.......6
......(front)
Ignition Coil Connections:
............(back)
.|.5..2.|..|.3..6.|..|.4..1.|
