Starting issue
I have a '93 Vette with an occasional starting problem. After the car has been driven and then sits for a period of time it will not start properly. It may just turn over but not catch or it starts and the idle is very rough. If it starts with the rough idle it may clear it self in a few seconds or I may have to turn it off and try again. Sometimes I may have to try several times. Has any one had this experience?
The car has 46,000 miles on it. New plugs, belt, all fluids and filters but no real tune up. It should not be the distributor unit with this low miles. The fuel pressure regulator is working properly. I'm guessing an electrical issue also, but hard to pin point. Hoping someone else has had this issue to short cut the process of elimination.

I'm betting you have a bad fuel pressure regulator. Check the vacuum hose to the FRP for fuel in it. If it is wet, it's probably loading the manifold up with fuel which makes hard starting and rough running till it clears out.

Exactly what I was thinking as I read the original post. My car caught on fire because of a ruptured fuel pressure regulator diaphragm, so fix it ASAP.
