I have a 1998 chevy tahoe w/350 automatic. When I start the truck sometimes it takes a few more cranks than it sould to turn over. Once started it, again sometimes. Idles poorly and may kill. I have changed oxygen sensors(due to diagnostic codes). And changed a couple fuel injectors(mechanic diagnoses). I have read other posts where the problems of the cold start point to the fpr, but my problems seems to be a little different. I am about to change the fpr to seee if it helps, but before I do that, does anyone have any other ideas?

Test your fuel pump pressure and for vacuum leaks. When was the last tune up? PCV?

Last mechanic said the fuel pressure was fine.
