I have a 2001 ranger 4.0 it will run fine and turn the motor off and it won't start back up. After a while it will start and run fine. I put a scanner on when it would not start and it said I had an open circuit to the fuel pump. Does anyone know what causes this and how to fix it?

 

thry the fuel pump relay. this is not solid advice but i had an intemittent relay on my 93 that drove me crazy

 

I tried swapping the relay already and it did not help
