Hello,

I have a Liberty I bought new with 6 miles on it, now it has 150k. I have maintained it myself, regular oil changes with mobil1, new NGK plugs every 30k, filters, etc. have never had an issue with it, except for a couple of u-joints and of course the window lift plate breaking.
Anyway, I was driving home last night and when coming to a stop at a light it died, put it in neutral and started right back up, ran fine all the way home, only like two miles. Went back out about 30 minutes later and wouldn't start, will turn over just won't start.

What I have tried:
Used an Innova scan tool and got no DTC's
check for fuel at the Schrader valve, no fuel in line
checked the fuse on side panel of dash, replaced with another just to be safe
Swapped ASD relay with the high beam relay
Checked fuse in PDC ohm's fine
Replaced battery in key fob

Still won't start, I have been searching all morning and even tried a few things from the 2006 FSM that I found online but no luck, at this point I am trying to find out how to remove the test/remove the fuel pump.

If anyone has insight onto another test or any additional directions to troubleshoot I would greatly appreciate it.

Do you hear the fuel pump turn on when you turn the key on?

no, and no fuel pressure at the rail, just making sure that, before I spend 300 bucks on a new fuel pump, it is the issue. I will be dropping the tank tomorrow and pulling the fuel sending unit and can bench test the pump at that time.

Replaced with pump/screen only, didn't buy the whole sending unit. But she is back on the road.
