[QUOTE="floridadiesel83, post: 1565900, member: 36999"] so today I took the truck to the gastation and filled her up . on my way back she died 3 times and the rattle got somewhat louder . made it home and she wouldn't start at all . have fuel pressure from the lpfp . could that rattle noise be my hpfp ?its the original pump . I didn't see any shavings in the fuel filter .checked that first . I checked for codes and had p2291 injector pressure to low . waited and let truck cool down for 30 min and she fired back up but died again after 10 seconds . if I cycle the key few times she will start and then die after 10 seconds again . I have a feeling its the hpfp but wanted to get some input on it . I know on the 7.3s when the pumps go they wont run when the truck is hot and soon as it cools down it starts again . not sure if the 6.4 is the same with that . [/QUOTE]
