ive been having this problem for a bit.. when i shut my truck off after driving and getting it up to operating temperature.. i have about a 10 minute window of bein able to start it without touching the gas, but as it starts it coughs and hiccups and doesnt wanna run.. but then smooths out. after that 10 mins, i have to pump the gas, then it really coughs, but runs.

vapor lock possibly? i dunno, figured i'd ask to see if anyone else has run accross the same problem. Thanks guys!

 

I had a simular problem. Turned out the timming was off for me.
