1997 Pontiac Grand Am

this car ran strong on a 600 mile trip good. Now you cant get it started. As soon as it starts it stalls and when I try to start it again it turns over but wont start. Its getting too much fuel. Replaced fuel pump, fuel regulator, fuel injectors, computer, ignition control module, air temp charge sensor, spark plugs, starter. Car is still getting too much fuel and if I mess with it enough it might start then has cylinder misfires. Any clue what else it could be?Car has quad 4 and has been rebuilt. Replaced map, o2, crank, coolant temp, and throttle position sensor. All sensors have been replaced. Computer check throws no codes. This car is a real puzzle any info you have would be helpful.

Change the map sensior. If you have good vacuum to it, its probably bad. That's if you can keep it running long enough to check vacuum. This little unit will make the engine flood like you wouldn't believe.
