Hi!
Replace if you haven't done so:
Air filter,
Gas filter,
PCV valve,
Spark Plugs.
Remove the IAC solenoid (2 screws), using a rag wet with fuel injector cleaner, wipe it clean. wrap the rag in a pen or pencil and clean the solenoid housing, make sure the far end, where the solenoid's tip seat is is clean, be careful not to scratch the walls.. DO NOT APPLY FUEL INJECTOR CLEANER DIRECTLY TO THE SOLENOID OR HOUSING..
When you replace fuel filter, dump the contents of the old filter in a clean container to check the status of the fuel tank.
Keep me posted!! Good luck!!
I am a retired GM dealer tech and i can tell u that the problem u have is that the electric fuel pump is sticking, nothing else causes this, the techs who said your fuel pressure was ok I am sure were unable to duplicate the no start, of course the fuel pressure would be tested and show ok, the important thing here is mileage, over 100,000 miles the electric fuel pump has reached the mileage that it can be trusted to always work, I have seen this problem many times in my 40 years as a technician (25 of which I specialized in automotive electronic systems), I was given just about every car that had these types of mystery problems with starting, never failed to fix even one. My recommendation is to replace the fuel pump, below is a picture of the fuel pump assembly, might as well replace the whole thing, it includes a new sending unit for the gas gage, the real money here is pulling the fuel tank out of the car to replace the fuel pump.
Like I said replace the fuel pump and the problem will be solved

Thanks for the evaluation. There is only 76,000 miles on the car, but as you can imagine by the year and the mileage, the vehicle was not used much (old man owner) and then sat around for a few years through an estate issue. Would those circumstances cause the fuel pump problem just the same as if it had excessive mileage?
