Fuel Pump/Turbo Help
Hoping someone could help me. I have a 2006 Ford F350 6.0l dually with 55,500 miles with no upgrades but a turbo back exhuast. I noticed last week when starting my truck up in the morning in the garage that when waiting for the glow plugs to cycle that my fuel pump is humming really loud and will run like it is priming the fuel system for a good 30 to 45 seconds, maybe longer and just before shutting off it makes a gurgle noise. I have even cycled the key and got under the truck and put my hand on the fuel pump to confirm that it was the fuel pump itself. I don't remember it doing this before. My truck also feels like it is lacking power and when I floor the gas pedal it will tach out at 3600 RPM's but has no power and the speedometer barely moves. There is no white or black smoke coming out of the exhuast. Also a few months ago I had my truck in for warranty repairs and had them look at my exhaust system. When I turn the truck off (not all the time) it would sound like I had marbles in the exhaust system. They told me it was my catalytic converter and when they told me the price I just firgured it gave me an excuse to put on an aftermarket exhuast. Just last week I put on a 4 inch turbo back MBRP exhuast system. After it was installed the notice the same sound but even louder. Well this evening when inspecting my fuel pump again, I had the hood up and noticed that when I turned the truck off the marble noise I would hear in the exhaust sounded like it was coming from my turbo. Like the bearings are going bad.
Two questions, is my fuel pump on the outs or could it be something else causing it to make this noise and have no power? Second, is my turbo on the outs also, even though I have 27 to 28 pounds of boost? Again, when I floor the truck it has no power like it is being defueled.
Thank you for your help in advance.
