My 6.0 has been gettin a p0300 and with the test key bump is 45 then i tuen it over and its 45 and when i rev it , it goes to 40 it seems like it gives it less pressure..pump is like couple yrs old but its been parked for like 2 yrs i think the pump w bad
I think probably the flow back valve in your fuel pump may be just a little slow I wouldn't be worried about that it's my vehicle as long as it maintained a minimum amount of pressure while cruising
Sounds like you have a fuel pump. Fuel pump, hose, or pressure regulator that's leaking by. Symptoms usually are long crank. After setting a while, or you may have to prime it. In order to get it to start.

Be sure to check your fuel filter. Cause it might be trying to stop up. You're not getting enough flow.
@@NobleAutomotive new filter too I thought it might ve been that but it ain't still.same pressures . I think it's m y pump
@@joeroe2839 Yeah, does sound that way or there's Screen. on the bottom of the pump sucking together? Either way, it's a new pump.
