My truck doesn't start up right away, it takes about 3 to 4 turns of the key to finally crank. It wants to crank but does until the 3 or 4 turns. About 3 years ago I replaced my fuel pump because it was doing the same thing and finally it just didn't start up. Well this summer it started doing the same thing so I was like my fuel pump is going out again. Well I replace it 2 weeks ago and it started like a champ, however a week later it started to doing the same thing. Does anyone know what may be causing this?

 

fuel pressure regulator?
