I'd hit it with a dose of starter fluid. If it does not fire, you know it's totally electrical in nature. The next challenge of course is figuring out why the ignition system is not powered.

I've used that it does fire to the extent that the intake plenum pops up

I'm going to get new fob batteries. Possibly it's the anti theft

Sounds like you have a fuel issue. If it lights off starter fluid, you are getting spark. Assuming mechanicals are correct, all it takes is spark and gas. You obviously have spark. Better look to the fuel delivery system.

Look at the fuel pressure regulator,at the bottom there's a small clear tube that runs to intake,if it has fuel in it FPR diaphragm is ruptured, also check for blown 20amp fuse at OVP located under plastic cover PS firewall,hope it helps
