   Hi,
   First, the fuel pressure is supposed to bleed off after that long so there are no leaky injectors.  That would have been my first guess...  Second, pull the vacuum hose on the fuel pressure regulator and see if the fuel pressure goes up about 8 to 10 pounds.  If the fuel pressure stays the same replace the regulator.  Third, replace the temperature sensor for the computer.  There is one for the computer and one for the gauge or light.  Anyway, make sure you replace the one for the computer as it tells the engine it is time to richen up for a cold start and it sounds like that is not happening.  I would assume you have checked the air meter for proper operation as that sounds like a problem too.  A Haynes manual would be great since that will give you the process to check the air meter and other sensors on the truck.  All you need is a volt/ohm meter for reading values.  Lastly, I would be looking at the distributor for the presence of oil on the optical shutter wheel and the pickup and receiver.  It sort of works like the computer mouse where there is an LED and a receiver.
