SOURCE: 1990 gmc 6500 topkick with no spark or injector pulse

You are jumping to conclusions. Slow down.
No spark AND no injector pulse indicates none of the desired outputs were triggered. The ignition module makes spark when it receives a crankshaft position sensor signal, and then transfers control of that spark to the computer after it starts. The module takes its crank sensor signal and generates an RPM count that it forwards to the PCM(main computer) which is used for triggering the injectors and controlling timing. SO, if you had a bad crank sensor OR a bad ignition module, you could lose both spark AND fuel. a coil would not disable injector pulse. modules RARELY fail in a manner that disables RPM reference to the computer causing it to not fire the injectors...At this point, I would TEST the crank sensor as the next step. If its easier, 1 of the wires on the module goes directly there so you can test the crank sensor at the module.

Testimonial: "great info, thanks!"

SOURCE: bmw 525i 2002 non start,no spark,no pulse at coil,code

If your getting no fire at the coil. that's why you're not getting fire to your plugs and therefore it won't start. Change out your coil. This should fix the problem.

How do I know what wire feeds from the ignition switch to the cdi as none of the colour match at both ends

with the ignition off ,use a multimeter set on continuity ( ohms)
place one lead on a wire at the ignition switch and the other end on a wire at the cdi when you have a circuit mark that wire and so on till you have identified all the wires
then turn on the ignition switch ans set the multimeter to volts dc and check which of those wires now has a voltage reading

Why is my 97 Honda 4 wheeler not getting fire

There are three items that are connected together needed to create spark on your 1997 Honda 4-wheeler, regardless of which model it is.
Before we go through a checklist of these three important parts, look for a black wire with a white stripe that runs to the ignition switch and kill button from the CDI box. Disconnect this wire before it gets to the ignition switch and kill button, then check for spark. The most likely cause is a broken kill switch on the handlebar, or shorted ignition switch. Such a condition grounds this wire and kills the spark.
If this test did not restore the spark, continue reading...
Here is what is required to create a spark.

First, the alternator has one coil which generates a high voltage--about 125 Volts AC for the CDI ignitor box.

Second, there is a pulse voltage generated once every revolution of the engine that goes to the CDI box. This pulse causes the CDI to dump its stored energy from the 125 volt line into the primary of the ignition coil.

Third, If the two connections of the wire that runs from the CDI to the Coil are BOTH SHINY clean, the ignition coil will generate a spark.

If any one of these 3 don't happen, the spark will go away. Of these three, item 3 -- one or two tarnished and/or dirty connectors -- is the most likely cause. Just an added resistance of 0.3 Ohms or more in the CDI to Coil connections will cause the ignition to fail. No other wires have to be this clean.
