What would cause my 12v pink power wire running to my icm and ignition coil to be powerless?

Hi I have a 1996 chevy s10 truck/ with a 4.3l v6 vortec. A few months ago the batterey, the alternator, and the fuel pump were all replaced to succesfully get the truck running. Witch it did for a short time. The truck ran great with no issues for a few days. One night we started it to show a friend, the next morning the truck was dead. We tried and tried to get it started but no matter what we tried it would not start. So we moved on to doing some basic diagnostics and came to the conclusion that we did not have any spark or fuel. So we proceeded to replace the ignition coil, ignition control module, crankshaft sensor, and the distributor cap. And still we have nothing. No spark and no fuel. So I got a little more in depth in testing and proceded to test the pink 12v power wire leading to the ignition module and ignition coild neither have any power going to when key is on position and when cranking engine.I am at a loss please help me diagnos this problem so that I can proced to fix it thanks. My name is drew.
