I have a 2003 Kia Sorento one day it cut off sound like it wasn't getting any gas so I changed out the fuel pump and it crept right up but a couple of days later it went off and would not crank I changed out the mass airflow sensor and it crumb right back up a couple hours later it went off and would not crank what do I do next

Did you try changing the Fuel Filter?  That did it for my Kia Sorento 2004.

There is a black rubber button reset switch right next to the air box, press it sounds like the problem i had its a fuel pump reset (just in case of a wreck it kills the car) but there is a tiny ball in there and if it is rattled a little too much it will fall and you need to press the black looking button to reset it....took me like 4 months to figure it out

i had a similar problem and called the dealer during lunch hour. i talked to a mechanic, the distributor in these vehicles is plastic, and is prone to cracking.not just the cap but the body also, I have been taking the cap off and wiping the moisture out of the cap. or replacing the cap but the problem is I need a new distributor. just a cheep way to get rolling is cleaning the inside of the cap, especially when it is very damp or the outside temp changes alot during the day. good luck.

SOURCE: cranks but won't start like it has no gas

did you reset the alarm/immobiliser system every time the power was disconnected???

SOURCE: 2005 kia sorento Fuel Gauge says empty with 1/2 tank of gas.

Fuel sensor is not working well. Just changed mine today for the same problem.
