Unhappy Engine won't start. Replaced ignition coil, distributor cap..

I have a 1997 TJ Sport.

So today as I was driving, I put it into 2nd and the engine bogs down and then it just shuts off. I try to crank it up, but it doesn't. I had to push the car into a shopping center and then I try to crank it again, but it doesn't start up.

I figured it would be an ignition or fuel problem. One of the spark plug wires had some corrosion, so I ended up replacing the spark plugs, wires, distributor cap, rotor inside, and the ignition coil. I crank the engine and it starts up, but then it dies after a second or 2.

I push the throttle in all the way, crank the engine again and it just keeps cranking.

I purchased some starting fluid and spray it into the intake. Crank it and it runs for 1 second and dies even if I push down on the throttle all the way.

I tried this 5 more times and the same thing happens each time.

I checked the fuel relay by using the horn relay and it still doesn't work.

I noticed there is a fuel valve on the fuel rail so I pushed on it and no fuel comes out. However, when I turn the key (without starting the engine) a couple of times and then push on it, a little bit of fuel comes out.

I'm thinking about buying a fuel gauge tomorrow and screwing it into that port to see what kind of pressure I'm getting when I crank the engine.

Could it be a fuel related problem like a bad fuel pump? Has anyone had these symptoms before?

Any help would be appreciated, thanks!

Drop the tank and replace the pump and do the fuel pressure regulator while you have the tank down.

Hey guys, so I checked the fuel pressure and it's reading 5-6 PSI when I turn the key to the "ON" position. When I crank the engine, it's giving me the same reading. I dropped the tank and now I have to buy a quick grip to open the white cap.

Here is a video of the Fuel pump in action. Is this enough power?
