2003 Kia Sedona engine cranks has spark no fuel

I bought the van used a month ago the said they changed the timing belt and the fuel pump and intake gasket. First the starter acted up not wanting to turn the engine over I had it rebuilt and out of the blue the thing won't start cranks very well checked spark. It does have spark. Checked plugs and the are completely dry so I checked fuel pump. When u turn key on it makes a thud sound so I pulled the lines and tried again no fuel comes out so I changed pump my self with another and still the same. I check all relays and fuses that I could find still nothing. I was wondering is there a sensor that runs off either crank or cam that would control fuel only and not spark since I have spark and no fuel and or is there an air gap that controls fuel system that could be a miss since they changed the timing belt. I am mechanically inclined and have some electronic knowledge as always more indepth answer would help thanks.
