It's mounted under the coils so you have to remove the coils first. That takes a special 4.5mm socket to get the coils off.
Here are the instructions

No, you don't move the engine. You just have to fight to reach it. Welcome to our world........LOL

Hammer Time, in that diagram is #6 the Crankshaft Position Sensor? It wasn't the darn Control Module after all, it tested out perfect @ 2 different autoparts stores!!! Dangit!!! So, now I'm looking into the CPS!! Thx for any help!!! Back to the Drawing Board. That part was a beast to get off!!!

Yes, the CPS is under the Module.
Test to see if you have injector pulse. If you don't have injector pulse or spark, then the crank sensor is likely. If you have injector pulse, forget the crank sensor.

Okay, changed the CPS and the car still isn't starting. It is doing everything except turning all the way over. Now, this car has a carburator. No fuel injection. Where do I check now: I changed the Starter, serp belt, water pump. I have spark, the coils are fine, module fine... Still no start, where to look now? HELPPPPP!!! I'm gonna try the battery next. After that I'm stumped again!!!

You don't have a carburetor. You have throttle body injection. They never made a 2.5 with a carb.
You need to stop throwing parts at the car and start testing. If you have spark, then you never should have changed the module or the crank sensor.
You need to test the fuel pressure and injector pulse before going any further.
You can use a noid light bulb to test the injector pulse.

Thx Hammer Time, alright, not throwing any more parts @ the car. Now, I'm testing everything that can be tested. Will try the noid light... How do you use it? That is new to me? But, I will try these things and let you know how it turned out!!!
Thx

You unplug the injector plug at the top of the throttle body and plug the bulb into it and then crank the engine. If the light flashes, everything is working at the injector.
Before you go looking for that, try this. Remove the air cleaner and spray some carb cleaner into the intake while someone tries to start it. If it starts and stalls, then you know you have a fuel problem.
Bad fuel pumps are very common
