Hard to start in the morning. Also stalls

Car cranks in the morning but will not start or starts then stalls and will not restart for a short period of time. Service engine light comes on some times after this happens. Replaced plugs, wires, fuel & air filters, PCV valve and one coil pack. Car ran good for three days then problem started again.

This sounds like a fuel pump check valve problem, if the fuel is not kept in the filter and lines by the check valve it drains back into the fuel tank and causes the kind of problems you are having, you can check this by hooking up a fuel pressure guage at the test port on the fuel manifold that supplies fuel to the injectors, run the engine and shut it down, note the fuel pressure at shut down (with the test guage hooked up), walk away for an hour, come back and check the pressure, it should not have dropped more than 5 PSI You can buy a universal fuel injection pressure tester for about $25.00, cheaper than having a shop run the test. If the pressure drops you found the problem, bad news is the check valve is in the pump, the pump is in the gas tank.

If your car starts while cold or first thing in the morning etc, only to stall shortly afterwards, and will not start back, but restarts after sitting for some time, your catalytic converter is clogged up, restricting the flow of exhaust gases.

No codes would point to fuel problem such as low pressure.
Was the car left overnight at the shop so it would be a cold start for the mechanic ?

The way to test a fuel pump is to put a pressure gauge on it in the morning when it is cold when you have the problem. If the pressure is low then your fuel pump isn't working when it is energized.

If it is high, but it is still hard to start, look at a fuel injector being plugged up.
