No fuel and spark to trailing 1 coil
I’ve searched and can’t find a thread for exactly what I’m trying to figure out. My first issue started when I replaced the plugs and wires, all the plug wires were connected correctly and after changing started the car and had a very rough idle, so bad shook the plug to the maf loose. T1 wasn’t getting spark, and before that the car ran fine. I screwed up and let it sit for over a year and not it’s not getting fuel. I drained the gas and put in 5 gallons of premium before trying to start it again. I pulled the fuel pump and jumped it off the battery and it works, put it back in the tank and tried jumping the fuel pump jumper plug and nothing. Ive checked the fuses and all look good. I have zero knowledge of this car. And again sorry for posting about issues hat have been talked about already just couldn’t find anything that helped so far

Forgot to mention I have a n/a vert and the problem with spark to trailing 1 happened right after I changed my plugs and wires, I used import direct wires from oriellys and Ngk platinum plugs

Just to be clear, can you define what you think "correctly" is when regarding the plug wires? The Haynes manual documented this incorrectly, so for years people have been confused. This bad info is all over the web as a result of this.
Do you know how to use a multimeter (DMM)? It would be helpful to know if you have voltage at the pump itself. There is a fuel pump relay, as well as switched resistor ahead of the pump, you will want to start investigating there if no voltage at the pump. These circuits are easily identifiable in the factory service manual (FSM) which is downloaded for free in multiple places (should be linked in several stickies on this forum).

3 of the plugs have spark, both leading and trailing 2, and I’ll pick up a nice multimeter and start from there, I have one but it’s super basic. And I haven’t really used a multimeter much but I’m sure it’s easy to figure out. And I have a Haynes manual... that’s what I used when I swapped the plug wires. What is the correct way the wires should be connected?

For what it's worth, Haynes should have the factory wiring diagrams in the back of the book, from what I remember. Should help you with the fuel pump if you don't prefer to use PDF/computer.
Just remember:
Leading = Lower
Trailing = Top
Rotor 1 is the further forward (closest to the nose of the car), rotor 2 is behind (closest to the cabin).

Would this work to test if I’m doing it solo and have the key in the on position and wasn’t cranking?
and when I did it this way I got 8v reading
I checked voltage from the ground and black with stripe wires, is that the power for the pump? (connected to the fuel pump side) not the harness side.
And is the the fuel pump jumper?
