Welcome to the forum.
How many miles on the 3.7 engine?
Were the correct KJ spark plugs used as per the under hood sticker? Gap checked?

Having the same problem with stall after start sometimes. Just replaced plugs (old ones were worn out) having same issue. Yes I used the correct plugs. I can hear the fuel pump when the key is turned.

I have a 2005 jeep liberty with intermittent cranking problems. I just found the best article about this problem at Ricks Free Auto Repair Advice.com I had checked all the simple things like battery, grounds, actuator pin, sensors, starter, relays, and fuses. I am pretty sure my problem is with my ASD system. I can crank it by jumping the starter relay but it will not start... I read somewhere if you just pull the ASD fuse and relay it clears something about the static build-up. I am gonna check power at the ASD fuse the next time this happens. Then go from there.
