You still need to check basics before talking computer. I would look at the crank sensor. The flywheel is a common issue as well for no spark situation. Have it checked to verify.

There is a trigger on the wheel that cracks and there is no signal sent to the pcm. A shop with a scan tool can verify the signal.

Ok, it has a distributor. That needs to be verified that it is working as well. You need a scope now to check that. I think you are going to need help from a shop from here on unless you have a scanner and a scope.

By the way, did you check the timing belt.

The 3.0 has a belt. The 3.3 and 3.8 have chains. Do you tell me the right motor?

Ok. Back to square one. Without seeing it, I still think you need to have the crank and cam sensors scoped to see the readings and see if the signal is getting to the pcm.
