Default Intermittent starting issues

I have a 2002 Coupe that may or may not start. This started a few weeks ago, got in the vette one day and it would crank but not start. Hit it with some starting fluid and it started but for about a minute ran very rough. Drove it for a week and twice coming to idle it just stalled but started back up. Few days later it again would crank but not start. Later in the day it started just fine. It's a 50/50 shot if it starts.

I wonder if his check valve is bad and allowing fuel to flow back thus giving him the long crank and no start. Mine did that but would eventually fire and be fine. I never replaced the valve I just turned the key and waited a few seconds for the fuel pump to spin up and then all was fine.

running rough and stalling though sounds like it is starving for fuel though and more like a filter issue...at least thats a cheap place to start
