Car runs fine after staring but after sitting over night loss of fuel pressure. Need to pump and crank to get pressure up then runs fine all day. I'am told its the fuel pump. Just need a second opinon. Is it the fuel pump that maintains pressure while sitting or some other valve, regulator. Thanks Phil

Could be the fuel pump, fuel pressure regulator and a leaky fuel pump check valve-also to include fuel injectors
