Although it's getting fuel to the rail, it may not be putting enough pressure behind that fuel to keep the car running. I would suggest performing a fuel pressure check, and a compression check as well. It's also possible that the exhaust is plugged, possibly from a failing catalytic converter. An exhaust back pressure check would need to be done to confirm this. Because all these tests require special tools and knowledge, I would recommend having a qualified professional, such as one from YourMechanic, diagnose your starting problem for you and make the correct repairs.
