7.3 NO BOOST

Started the truck up this morning, decently cold, weather dipped in the single digits last night. Not plugged in. Cranked over, idled rough, no big deal. Drove for about 5 miles around 35mph, no boost what so ever. Gauge read 0 psi. I could hear a "air" sound, like when the wastegate dumps, consistently when on the gas. Truck ran like a slug.Pulled over, popped the hood, nothing catastrophic... all looked good. if I goose it in neutral I can get .1 psi..

My quick searches suggests that its the waste gate or the waste gate solenoid. I am up at school, only have access to limited tools and its finals week

I can get a circuit tester and check the solenoid, it should be closed when the truck isnt running.

Just wanted to get everyones opinion. Cant get under the hood until tomorrow afternoon.

sounds like the EBPV could be stuck closed

Anything diagnostic I could do? This wouldnt prevent the turbo from building boost would it?

when its stuck closed it will cause low power no boost and a air rushing noise from the exhaust.
you could try unplugging it, with the key off the ebpv should be in the open position. the plug is a 2 wire plug with a metal lock at the base of the turbo in the front.
if that dosnt work it could be full of carbon causing it to stick which would require you to disassemble and clean

The "air" sound you are hearing is a lovely butterfly valve in the exhaust system on the back side of the turbo that assists in cold weather to warm the truck up. There are a few ways around it such as a blank exhaust housing with no valve in it or you can take the housing off, and bust the valve off the shaft and let the shaft free spin when it tries to cycle on and off.

Is there a way to just unplug the ebpv actuator?

Ive seen people unplug it and seen people un hook it. There is a plug by the front side of the turbo that can be un plugged and it will disable the EBPV.

next time I started her up, all was fine. This morning, 9deg, no problems. Should I tear down the EBPV and clean it out?

As long as the valve is not physically stuck, you can unplug the connector for it down near the pedestal and it will remain open (inactive). I've had mine unplugged for about 2 years now.
