Use a test lite and follow voltage from battery B+. The positive and negative battery connections have to be good on both ends. Check for voltage at fuses in fuse box, some fuses are hot all the time, some go hot with key on. Check for fusible links, I forgot to look in diagram? I also looked at wiring for your starter motor, it shows a security system. The security system will disable starter motor. I can't be certain your security system is the problem? Does your key have a pellet in it? Any applicable trouble codes? Unless you can do some testing, I'm not sure which route to take? Is it an electrical issue or is your security system involved? YouTube has a bunch of videos about bypassing the vats/pass key system. If that is the problem. My info on your model year, isn't that great.

225 F equates to 107.22 Celcius normal operating range for engines is 85 c(185F) to 98 C (208 F) 100 C is boiling so 212 F is maximum temp anything over is excessive and requires attention

Not a reset for the old car. They work or don't. This is a search and fix problem.

I bet it shakes under light/moderate acceleration and will also stop shaking if you let off the gas? If so your best bet is to bring it to someone who is very good with driveline. It is fairly common for worn drive axles to cause this symptom however an engine misfire will also cause a similar symptom. at 45 miles an hour overdrive engages putting a lot of load on the engine. Weak ignition components can cause a misfire that only shows up under this extreme load. It is very important to have somebody who is very good at solving these issues take a look at it and determine exactly what it is. I have literately had customers admit defeat after installing every ignition component, every sensor, and even transmissions only to find out a few hundred dollar drive axle was the problem.
