Slow to start. OK after several attempts. fuel filter is new. Spark plugs are new. Runs well once started. Fuel pump/sending unit was replaced but I have noticed that fuel guage sometimes "twitches". Do fuel injectors have their own "high pressure" pump or distributer on engine? What about a fuel pressure regulator? It runs good but it should start easier. THANKS ! for any ideas..

Hi rpisha, welcome to 2carpros and TY for the donation.

Check the fuel pressure with a fuel pressure gauge to rule out a failing fuel pump and also test the coolant temperature sensor and also fuel pump relay
