Scan for codes and check fuel pressure first. Check for vacuum leaks like a hose off or soft and leaking.

Ok just checked the codes didn't think of it before cause the light wasn't on. It shows code 34 I looked it up and says the speed control solenoid open or short is that a wiring problem or the part is no good

It cold be either for the speed control. But that shouldn't cause hard starting. Check fuel pressure and vacuum leaks.
