No spark.

With the key on engine off you should be getting battery voltage on the Yellow/blue wire to the ignition coil. This vehicle has the 2.6l engine and does not come with a control module for the ignition. It does however, have what is called a power switch (located on the underside of vehicle, driver side of engine) it has two wires running to it a green and blue. The blue wire your seeing may just be a test connector for diagnositics and is not used. From what I've found there is a blue wire splice into the blue wire running to the coil.
The power switch is used to fire the coil so you need to make sure you getting a signal from it. Hope this helps

All I've found is a wiring diagram for the ignition system. I'm working on getting just an image of that but have been unsuccessful. I've sent an email to get some support for this. The wiring diagram references this "power switch" location as: "underside of vehicle, right side of engine". As soon as I can get more information I will send it your way. I've got your question saved so I can get back to you.

Here is a wiring diagram for both engine the distributor, coil and power switch. But I would say you need a crankshaft angle senor which is not in the distributor it down on the engine block.

The power switch has one green wire and one blue wire. Note that the green wire at the switch also turn yellow wire then blue wire so keep this in mind when searching.
Before you go looking for the power switch make sure all the engine-to-body grounds are adequate. Because the power switch is grounded to the engine it is critical that grounds connections are in good condition. So, if they're covered (tape, conduit) uncover and make sure they're good first.

Here are some location diagrams I found

Good to hear! Check those grounds I mentioned and signal to the module. Let me know how it goes, Ty
