2002 Toyota Tundra

Engine Performance problem
2002 Toyota Tundra 6 cyl Two Wheel Drive Automatic 75000 miles

The engine turns but won't start. I installed new battery, new feul pomp, checked the spark plugs, IFI relay clicks, got power on Circuit opening relay, all fuses under hood and under dashboard are good, and there is power by feul pomp. However the pump does not kick in (does not make the tipical two second sound), so, aparently there is no fuel flow. Is there a problem in PCM? What are my options? All this happend after last thursday's cold weather when I tried to jumpstart the truck. Halp please! What are the steps for donation?
