fuel filter and also check to see if it's on the right way. it will cause low pressure. pressure should be 60-66 or it won't start

If the truck does not have any problems holding an idle when accessories are turned on, the Fast Idle Thermo is a likely source for the problem.
It has coolant flowing through it and acts as a choke.
