1991 S-10 fuel problem

I have a 1991 S-10 with a 4.3 . When it's cool outside in the morning it starts right up but only runs about 10 seconds and dies. It will start right back up but does the same thing for 10 -15 starts then decides to keep running.Once running it does fine. Doesn't do it when it's warm outside. Gotta figure it out before to long as it is getting cooler by the day. Thanks for any input and this sight is great. I get on it even when I don't have problems just to try and learn something if I do have future problems .Thanks again.

Check cold cranking fuel pressure and fuel filter.
Check for lose of spark or fuel when no start.
Any check engine lights on?
