GMC SIERRA BODY PROBLEM

1995 GMC Sierra • 180,000 miles

Just finished replacing the IAC[engine is a 5.7 ] now when I go to start it, it seems like it is not getting enough gas if I keep the key turned over and pump it a bit it catches and runs as soon as all of the roughness is gong the truck runs great turn off and on with no problem at all. When it sits overnight the prblem starts allover again. Is it a timing issue now? Thanx.
