Not sure what to make of this one...
I start the car and it runs for about 5 seconds then stalls. This will happen few times before she finally runs without a problem. Other than the choppy acceleration following the starting issue, she'll run like a champ all day. Obviously this starting issue only occurs after the car has been sitting all night... especially now that its been very cold here in Pennsylvania.
I have new plugs and wires and a new crank sensor.

Any Ideas?

Thanks

Change the fuel filter lately?

Sounds like your IAC (idle air control valve) Idk what you drive or what motor you have but on the 3.3 its under the throttle body. Take out the 2 screws and clean it up with carb cleaner. If the spring and piston come apart then it must be replaced

Too bad you couldn't leave a fuel pressure gauge on the fuel rail pressure test port all night and watch it while some else cranks it. Then see what the fuel pressure is at 7:00 AM. Pump or regulator. If both are changed, more reliablity and peace of mind

I would also be checking your vacume lines around the fuel pressure regulator. If they are full of gas, then its bad..
