if its a modern jeep it probably needs to have its immobilizer reset after changing the battery ask a main dealer
If you mean the fuel pump assembly yes. Fuel assembly is vague. But I assume you are referring to the fuel pump and float assembly that lives in your gas tank. There was a recall on some of the Xterra's because the wiring to the assembly was not protected well, the wiring would break and cause the Xterra's to die while driving without warning or you would come out to start your car and it just wouldn't start. You can call a dealer and give them your vin # to check and see if this recall has been performed on your vehicle.
Your battery is not charging. It is either due to a faulty battery or a faulty alternator. Get it changed.
have you replaced and or tested both coils? are you getting no spark on the intake and the exaust sides?
Catalytic converter gone bad
It should be no different than before. Just start it up. If it want start make sure the cables are tight. If this doesn't help you got other problems.

Check the charge on your alternater.
dead battery
Check the battery cables or starter.
Starter lockout relay, next to the battery.
either your battiery is dead or your starter is going out, probably the battiery though
Have you checked your battery. My battery died on me all of a sudden and I could not start my car.
Start with the easy things first. I had this issue and it was a loose battery terminal. The terminal had corroded to the point that the battery made poor contact. I cleaned the battery connections, but could not get the connector tight enough to make a good connection. I eventually replaced the cable (under warranty). The battery also had to be replaced as it had been drained and recharged so many times, it had lost its umpph. Another possibility is a bad starter solenoid or a bad starter. Good Luck!
If your 1994 Nissan Quest won't start, you might have a dead battery or a bad starter. You could also have a tank that is empty of fuel.
