You missed the most important parts of my story. First of all, you jumped the ASD relay and you observed the fuel pump runs. You're done. The pump circuit is working and there is no point in looking at that any further.
The second point is you must not have 12 volts at the pump when you are just sitting there with the ignition switch turned on. You will have 12 volts for only one second when you turn the ignition switch on, then it must go back to 0 volts until you start cranking the engine. If that 12 volts does not come back during cranking, that is because the ASD relay is not being turned on at that time, and that is almost always due to the failed distributor pick-up assembly.
What has confused the issue is your use of starting fluid. It is possible for that to self-ignite in the engine in the absence of spark, so that may not be the best test. You need to look specifically for spark. Start by pulling the coil wire out of the center of the distributor cap, then prop that end near a metal part of the engine, but not quite touching it. Have your helper crank the engine while you watch for spark jumping that gap. If you do not see spark, the pick-up assembly is the best suspect.
You should also check for diagnostic fault codes. Chrysler made doing that yourself much easier than any other manufacturer. Cycle the ignition switch from "off" to "run" three times within five seconds without cranking the engine, leave it in "run", then count the flashes of the Check Engine light. You'll get a series of flashes for the first digit, a short pause, a series of flashes for the second digit, a longer pause, then any additional codes will flash the same way. The last code will be five flashes, then another five flashes, (code 55), which just means it's done. You can go here:
