Wire colors diagram needed?

The IAC has a 4-pin connector with a pink wire (5-volt bias), a light blue wire (motor), a blue wire with white stripe (ground) and a dark blue wire (motor). The connector view is looking at the front face of the connector on the wire.

That's but now I've got another interesting question.

The question is I've got a 96 Chevy Astro van 4.3 it ran like a new one until a week ago I went to leave and turn key over nothing turns over but no spark and I already know what ur gonna say but nope it ain't that bc I've replaced distributor -coil - camshaft sensor-crankshaft sensor - ignition coil module -the pcm- and also changed plugs - plug wires I've replaced all of the ignition switch system and still no spark and check all hot wires from start to end and ground wires no brakes or cuts in wires everything getting power good but no spark even got a battery and I can't find nothing wrong with it and all is new no spark I've search everything can't find or figure it out

Please copy and paste that question in as a new question, we try to keep each question vehicle specific to make searches easier. Thank you.

It needs to be a separate question just like when you filled out the information for the first one. https://www.2carpros.com/questions/new
