Did you test the connector with a multi meter? If it were me, I would want to find out if the PCM is commanding the WGC to open or if there is a short to ground. If the PCM is asking for the waste gate to open then you have another issue to resolve.

Can your Edge read boost? How about exhaust back pressure?
Have you pulled any of your codes yet?

 

I havnt did the things you suggested yet.
Lack of know how and tools but Ill read up on it and get to it when I can.
I think i understand what you are saying ..........

 

I think im done with this truck...................
Ive spent thousands on keeping it running.

Not sure what Im going to get , I dont want a 6L and I dont think I can afford a 2008 or newer.

I dont want a Dodge , so i guess that leaves a Duramax?
Ill buy something to use for a few years until 2008 and up are down some in price.

Any ideas?

 

Have you got a s an tool like ae to hook it up to? Probly been asked, and where are you? Maybe an extra pair of eyes and hands could help!

 

I should have bought a AE a long time ago but i never did.

I dont need a hobby , I work all day and when I get home ( If I make it)I dont want to have to work on my truck.

 

i know im not super close but im closer than a lotta guys, im getting ae this weekend just so ya know

 

I get down to the coast often so ill probably break down in your neighbourhood someday.

 

I've thought about it alot - and I can't see ANY connection between these symptoms and wastegate. Am I missing something?

Does it do the same thing in neutral? Any extra 'play' or noises when you go from Drive to Reverse? (rear diff issue?)

 

2 mechanics Ive talked to both agree that this switch would do it.
Ive tryed it unplugged and its better , so I dont know?

It still doesnt seem 100% .

Rear diff was completley rebuilt a month ago.

 

I'm with you on this one. Acting like the brake is on while pointing downhill has nothing to do with the wastegate


This would be the first thing I would try.


Something isn't jiving for me.
Wastegates only operate when the engine is under heavy load and your truck won't roll even at an idle???

 

Instead of unplugging the wires have you tried just unplugging the red hose off of the turbo to see if it does the same!

 

Nope havnt tryed that.

 

I imagine it will roll down a hill in nuetral and shut off.
I mean it doesnt roll smothly and easily going downhill at highway speeds.
When you let off on the fuel the truck doesnt keep rolling at speed ,it starts to slow down just like you pushed the overdrive button or like a exhaust brake on a Dodge.

 

Are you sure we are talking about the wastegate and not the EBPV?

If the problem is only 'in gear' and feels (sounds?) like an exhaust brake - we must be talking about EBPV. If thats the case, there is NO HARM or future implications from leaving it disconnected - although ya prolly oughta protect the connector from shorting out...

The electrical connector for the wastegate is on the front of the spider/5way plenum in front of the turbo and the one for EBPV is UNDER the turbo on the turbo pedestal - it also has a wire retaining clip thingy ya have to flip up before unplugging it.

I got a real kick out of your willingness to get one of these new PITA trucks to replace the venerable 7.3. Maybe its just because I've gotten to a point where (I think ) I understand this engine and know its quirks - but the new junk appears leaps and bounds more complicated. Besides, there are no forums like FTE for them...

 

Jason he cleared it up a few pages back with a picture! I'm stumped!
