My 1988 Celeberity had the same problem. The car would start and run fine. When th car is warmed up it would not start.
I had fuel preessure and spark when the car wouldn't start.
The problem is the fuel injectors are batch fire meaning 1, 3, 5 injectors inject fuel and then 2, 4, 6. When one injector shorts out you lose the other 2 becaus there on the same circuit.
Mmprince4000 said this already buti couldn't figure out how to quote him.
I unpluged the wire from the injector on the front right ( you can only get to the front right and back left injector easly) and the car started up while hot and runs fine with a slight misfire because cylinder 6 isnt getting fuel.
I got lucky getting the problem injector on the first try if you have the same problem it could be any of the 6 injectors causing the problem.
If you have to pay someone to do the work you should replace all 6 injectors. Me im just gonna replace the bad one.
