Pumping the pedal does nothing for starting, that's only with a carbeurator.
Sounds like you might have a weak FICM, injector stiction, or other things.
What type of oil do you use? Oil filter? Oil change intervals? Battery CCAs? What temps is this happening in?
btw. All those answers will help in diagnosing what it could be.
