I just purchased this car - its in great shape and worth some work being done on it - the fuel injector has been replaced but it is a hard start after sitting for a period - say overnight or a workday
it takes 3 cranks and usually starts on the 3rd after which it will start right up and runs well

It was checked at a repair shop but since it had been running it was good - its just at a cold start it happens

It seems to drain the fuel from the line when it sits and takes too long to pressurize again -something in the line perhaps or the fuel pump maybe - fuel filter has also been replaced

If it's tbi it shold have 39 psi you may have to turn key on and let set for 2 seconds before trying to start. Toher wise check to see if pressure stay s around 39 psi after car is shut off if should stay there a few minutes otherwise the pressure regulator may be shot. Then if this fails take it to the repair shop so they can look at it. I have no further suggestions.
