The 'coil tower' is/are two Ignition Control Modules. These are located on the right side of the engine, right above the Crankshaft Position Sensor, which is located close to the oil pan rail. (Sitting in the truck, the passenger side is the right side)

Viewing from the bottom of the truck, look straight up from the oil pan drain plug.

Remove the plugs from the head. Insert into the coil wires. Make sure they are properly earthed on the engine. Crank the motor and check for spark at each of the plugs.
Refer to the diagram. Cylinders are connected as shown on the diagram in blue. 1 goes to cylinder 1(sparkplug furthest from coil pack), 2 to 2, 3 to 3 and 4 to 4(closets to coil pack).
To test the coil pack use a digital volt meter. Measure resistance between coil towers for coil 1(marked 1 in red on diagram) Value should be between 12000 and 14500 ohm. Do the same for coil towers 2.
Measure resistance between I and C1. If the measurement is more than 5 ohm the coil is defective. Do the same for I to C2.
Measuring voltage at I(Ignition start/run) to ground should be 10V.
I is connected to the 15A engine fuse. The radio interference capacitor is connected between this line and earth at the coil. Disconnect it to see if it cures the problem.
C1 and C2 connect to the powertrain control module.
Bear in mind that aftermarket coil wires may cause problems with misfiring, so see if you cant find an OEM coil wire to replace the broken one before replacing anything else.

What should a multimeter read on a continuity test on the coil packs? i'm getting 1.9,1.7,1.7


The multimeter can read the resistance and if it is not open or shorted out, I'd say that your readings are in the normal range, comparing each resistance with each other + or - 10%.

I looked up the resistance readings on my online resource, but they did not list it specifically.
---
I looked up the following on autozone.com:

There are 3 dual-tower ignition coils that are part of the ignition control module (ICM). The ICM contains coil driver circuits that command the coils to operate. The Powertrain Control Module (PCM) controls each dual-tower ignition coil by transmitting timing pulses on the ignition coil control circuit to the ICM for the proper coil to enable a spark event.
  1. Inspect the spark plug wires for proper orientation.
  2. With the ignition OFF, remove the fuel pump relay.
  3. Crank the engine and test for a strong spark on each cylinder spark plug wire using a suitable spark plug tester. Ground the companion cylinder spark plug wire of each cylinder when it is tested.

    If a strong bright blue spark is present on all of the cylinders, remove and inspect all of the spark plugs for proper torque, proper gap, wear, damage, and fouling. Replace the spark plugs if necessary. If there is no spark on any of the cylinders, test the ignition voltage circuit of the Ignition Coil Module (ICM) for an open/high resistance or short to ground, or test the ground circuit of the ICM for an open/high resistance, or a faulty ICM. The wire circuit resistance should measure less than 3 ohms. If there is no spark on any of the cylinders, or spark is weak or intermittent, test the IC circuit for an open/high resistance, or a faulty ICM. The wire circuit resistance should measure less than 3 ohms. If spark is present on one or more of the cylinders, inspect and test the spark plug wires for arching, cuts, rubbing on other components, and proper resistance. If all tests are normal, then the system is operating correctly.

Firing order. took the spark plug cables off and don`t know where they go back


First,look at the coils see if the towers are numbered.Each coil fires 2 cylinders!
look on intake manifold for fireing order display! The v6 engine fires from one bank across to the other in a straight line example,cylinders 1&2 3&4 and 5&6 at the rear of the engine or farthest right side. 1&2 left side faceing engine 3&4 in the middle. All you need to do is find cylinder # 1 hook up the # 1 wire to the # 1 coil tower to the # 1 plug or cylinder,follow the fireing order 123456,its simple if you cant see coil tower numbers look at another car with same engine that has distributor less ignition.The coil pack for the 4 cylinder gm has plug wire terminals or towers numbered as well.Only in a harder place to see like behind and underneath!

Car just stopped running. Lost power suddenly.


Find an inductive pickup indicator for spark. Place on distributor cap to see if spark is at coil internal tower. If no spark at internal tower, look at ignition module or pickup coil. Ignition modules are prone to failure on 626's. But if you have spark at tower but not at the wire end, then your rotor is gone.
