Hard start when HOT
1987 auto coupe--- alum heads
I have had this problem on going for some-time now. When I start the car from cold or even after storage over the winter its starts up immediately on the very first crank but when it gets HOT after driving and shutting down it cranks probably for 10 to 15 seconds and even that wont start untill the 2nd or 3rd try!!!!!
. I feel that something in the distributor may have a crack or pick up coil. I don't really know what to make of this
. Any input would be helpful
Thanks

Does is smell like gas like the engine is flooded when it finally starts up? If so it could be Fuel Pressure Regulator leaking fuel into the intake via the vacuum line. I had that issue on a camaro, would be hard to restart between like 10 mins to 2 hours after running, until the fuel cleared. Or leaky injectors.
Hope you've made some progress in the week since you posted.

First thing to check is the fuel pressure, hook up a pressure gauge at the rail and watch the reading while running and after shutdown.
2nd thing I'd suspect is the ignition module or something else in the distributor.
