My 01 buick regal starts fine when cold but will either start then die or just crank when hot. If I jiggle the peddle like it was carborated it will start runs fine when running. 3800 engine
This can be a problem with your starter so better check the starter or have it replace...
Hope that helps........
You can also do this:
Get a carbuerator cleaner and next time it refuses start do below -and tell me what happened.
Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.
Fuel pump and Injector/s checks out-start checking the ignition system-power to coil, coil/s itself,distributor pick-up,control module, Cam and Crankshaft sensors.
If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time
You probably need new mass air flow sensor you can get a used one for $30. if your fuel consumption has increased then that is most definately the problem.

Its
a hot start issue.
Can
be related to low fuel pressure or problem with crank sensor.
Also
it can be weak battery or starter.
But
possibilities are to be inspected to confirm what exactly it is.------

starter cranks fine. thought of the TPS or MAP sensors
checked fuel pump preasure and found good replaced all plugs checked wires for cracks and resistance and cheaked coil blocks for proper resistance all looks good
engine cold delays start engine hot start ok
3.3 v6 starts when cold dies after engine warms up will not restart till engine is completely cold
Runs fine when cold, starts to run rough after it is warmed up
