OK, your test definitely concluded that the coil secondary is open….NG But, be sure to check the plug wire with the ohmmeter before resuing it (or after you have made the new one included in most of the coil kits). An open plug wire puts more of a load on the coil secondary, and could result in premature damage to the new coil.
And yes, manipulating those amphenol pins and sockets is tough, even with the right tools. The first thing to do is soak the rubber plug in isopopyl acohol to loosen up the rubber’s grip on the pins/sockets. Do not spray WD40 or any other spray lube into those rubber connectors…These spray lubes can conduct electricity and will lead to short circuits inside the rubber connectors.
Removing/installing the pins/sockets can be tough (especially when you don’t soak the rubber connectors in alcohol first), it is super easy to get poked as well. It is tough to steady/secure the boot while trying to push the pins, so try to steady on a solid part of the block/lower pan while pushing….Maybe use a super small screwdriver to poke inside and catch the shoulder of the pin/socket, you don’t really care if you damage the pin/wiring of the bad coil while you are removing it. As for installation, soak that rubber connector in alchohol again, push on the shoulder with a super small screwdriver, the pins/sockets usually go back into the rubber connectors fairly easily once they are softened up.
