Question type: Maintenance & Repair

I have a 2002 GMC W4500. 5.7l gas job that has trouble starting and keeps
stalling out. i just replaced the fuel pump b/c the fuel level sensor was shot
and changed the fuel filter because it was due. i also replaced the distributor
module and distributor itself, the purge valve, fuel pressure regulator, MAP
sensor, and spider injectors. i tried adjusting the timing but nothing seems to
be helping. any ideas as to what it can be?
