I will check a few more things on it. thanks . And in my original post, I already scanned for codes and it came up clear btw.

 

I had a 2002 4.8 that was hard to start it would turn over but not crank it was a relay under the hood i switched it with another and solved the problem try it it might work. It was the fuel pump relay if I remember right.

 

when I get a chance ill try that. thanks

 

it was the fuel pressure regulator. thanks lukmoor. while i was taking the old one out the little oring fell in the fuel rails and i tried forever to get it out but couldnt get it. so i said f-it. should i be worried about it
