Hard starting when cold and hot
When I turn my car on I cycle my fuel pump like three times before I start it. I believe I'm losing fuel pressure when my car is off and im losing it fast. My car is difficult to start when its hot too. So what could be the issue? where and how could i be losing fuel pressure so quick?

you need to see if you can crimp off the return line and check for fuel pressure drop off. Its possible that your pumps anti-drian back mechanism has gone bad... or you could have a hole in the pickup tube from the pump to the sending unit.
If you crimp the return line and your pressure stays up... then your FPR is shot.
