I have a 89SC and it's been in storage for 4.5 years. Install a new gel yellow battery and a new fuel pump and check all fuse and wire. Clean out the fuel tank and notice the fuel leveler is all bad as well. Need to get a replacement for that. If anyone has a good one to sell me. Would love to get it. So back to no fuel going in to start the car. If anyone know something please help or know how to wire it up straight so I can fire it up and get it ready for a trip up to San Francisco from Los Angeles next month.

So what is the problem? Does the new fuel pump not run? Remember that the pump is not supposed to run until you crank the engine.

The turn over and no fuel in going in the fuel rail

Dude, that car was sitting parked still for 4.5 years and the old fuel pump and tank are excessively corroded just like the first pic you posted then I guarantee that the fuel line and filter is clogged with flakes of rust.
You’re going to have to pull the fuel tank out off the car and treat the rust with some cleaning vinegar and seal it with the por15 treatment to prevent it from rusting again.
I’ve had to do this total fuel tank system restoration on a couple MR2s I owned before, sure not fun or entertaining but the end result is worth it, starts up quick every time, idles smooth, accelerates smooth zero hesitation worry free cruising for many years to come

Yup. I'd yard out the entire fuel system and replace as much as you can and clean/treat what ever you cannot get replacements for.
Fair amount of work right now but better than a month down the road having to get towed home and then do it, or being bitter and then just junking the entire car.

Yea I was thinking the same thing. I'll drop the tank again when I get it up in Oakland and in a garage and really do a full rebuild on fuel system. Thank you
