The primary side of an ignition coil is not intended to produce a spark and it isn't wise to try. A test lamp or voltmeter can be used to check for battery voltage on the +side and for continuity through the winding. If the winding has continuity and a voltage is present then current will flow if the contact points or the trigger (optical, hall effect or inductive) and amplifier is working correctly. A 1990 model probably uses a trigger and an ignition amplifier

What color wire do I need to cut just to put a toggle switch on to kill engine on 1990 Chevy Cheyenne 4.3 liter

If you kill primary voltage to the ignition coil, the vehicle shouldn't run. Primary voltage to the coil is the positive side of coil. It's a pink wire comes from ignition switch to ignition coil. There are many ways to do something like this. You can kill spark, you can kill fuel, whatever.

Why am i not recieving sparks from the coilpack?

You need battery power and timing control from the engine. They spark is created is to energize the coil and then remove the voltage, creating a large spark on the secondary side. I don't really know if this is electronic ignition or the old points and distributor system, but I would look to see that power is getting to the primary side of the coil pack.

We replaced coil with new spark coming from coil

Check if there is any power going to the primary winding of the coil. There should be roughly 12 volts on side of the primary. If there is none check for a blown fuse.

There is no spark at the plug when pulled from the engine and engine is cranked.

If there is spark with a jumper battery connected, you need a new battery. If no spark with a jumper battery connected, you need a new ignition module.

No ignition to spark plugs

The coil has two seperate circuits 1) primary (is this where you are checking?) the thin wires at the base of the coil. and a secondary circuit this is your high voltage side the spark side and it needs the primary side to turn on and off in order to work youe test light should flash on the negative side on the primary circuit if it does not you will not have spark and your triggering device is deffective if it does flash then you have an open coil and it should be replaced.
Hope this helps you
