It's never a good idea to hunt for a problem by replacing parts and hoping to hit the jack pot. It never works and only costs you a ton of money you might as well have just spent on a mechanic.
Now, when's the last time you changed spark plugs/wires, and your fuel/air filters? If it's been way past the recommended service intervals, begin with this. Because it's hard to get accurate testing results for an engine not in proper tune.
Also, when you replaced the fuel pump, did you replace the filter also? And what about checking for water/debris in the fuel system?
As for you ignition, if your car is running, there's nothing you need to worry about between the computer and coil pack. And finally, if your car is only stalling once in awhile, and there's no codes, your computer is probably fine.
