FUEL PROBLEM

Chevrolet Blazer

I have a 1997 chevy blazer 4.3L 4 wheel drive. In order for me to get it started I need to prime the fuel pump by turning the key to the on position at least 3 times letting the fuel pump cycle. Otherwise it wont start. I switched the oil pressure sending unit which doubles as the fuel pump switch thinking that will help because my oil pressure was reading a little high at 60psi. Once I get the car started it runs fine and with no problems. I can turn it off and as long as I dont let it sit for more then 45 minutes it will start up again no problem but if it sits for to long then I need to prime the fuel pump again. And just this morning I primed the fuel pump about 5 times and it still didnt start but it was turning over fine. I still decided to jump the battery with my other car and that got the blazer started, im planning on changing the fuel filter soon but wanted to know if that may be what is causing the problem. I would appreciate anything you guys could tell me. Thanks
