Jeep takes 3 cranks to start (not usual common problem)

Ok so before I get flamed I did spend a lot of time reading on this, but I feel like my problem isn't the same as others. I see this very common problem with wranglers not starting and it's the fuel pressure regulator or valve. Maybe mine is as well but everyone that seems to have this problem says that they can leave the key on on for a few secs and it will crank right up. Well i have tried leaving it on on for a few mins or on and off and even left it cranking for 20 secs and nothing. It never starts on first or second try always third sometimes four. My jeep is a 2003 wrangler sport. Mechanics tell me different story so i said what the heck ill ask. After it turns on it runs perfectly fine and if i turn off and turn back on within a minute it will work. I bought the jeep like this so any light on this issue might help! I have next to no mechanic knowledge but i am
Willing to try anything! Thank you!

Try this and tell us.

Turn the key on for 5 seconds - but don't crank it.
Then off for 5 seconds, then on again for 5 seconds - without cranking it.

Do it 3 times without cranking, all right in a row. On, off, on, off, on, off.
Then the 4th time try to start it.

That will tell us if it's the pump or pump related or not.

Tell us what happened and we can go from there.

Crap man i cant believe i didnt think of that before well it did turn on first crank after doing that sequence i also noticed that the pump goes on for half a second or less each time the key is on on so i guess its the same issue? Fuel pump regulator? Or whole fuel pump?

Your not alone, my jeep does the exact same thing! exactly, i never crank it for 20 seconds tho, its not going to start, i turn the key, on, off, on, off, and it usually starts. IMO if it starts everyday for 2 months without a problem its good to go

That's a sign your fuel pressure regulator is not holding fuel pressure, which means it is allowing the fuel to drain down out of the engine and back into the gas tank. You need to drop the fuel tank to get to it but at least it is outside of the tank.

Here is a pic from when I replaced my leaky fuel pressure earlier this year. Tha's the top of the gas tank you see there.
