OK - You found a big problem. Lambda circuit is secondary to fuel pump. You may have more headaches with the Lambda but you are not starting without fuel pressure.
These are the thing I know off the top of my head.
Check/wiggle fuel pump fuse. Spin it to bust corrosion. Squeeze the contacts a wee bit together. Scrape contacts if full of the white stuff you see on battery terminals. Some say use a number 2 pencil in a drill, eraser side out, to clean off the crud.
Wiggle the red (fuel pump) relay in the front fuse box. Closest to the driver. Take it out put it back in. Spread the pins a micro bit with a single edged razor blade to make wider. Just make a better connection.
Run the lift test.
Change out a red one for a black one.
Run the lift test.
OK - that's the easy stuff.
Behind the air sensor there is a connection. Just below the black rubber bellows but definitely behind. That connection must have the correct wire to it and it must be fastened properly. Your fuel pump will not run unless that connection is tied into to the front red relay. First step, is there a wire connected?
