Well the truck is acting like a turd and using over 75 more in gas then is usually does for our work runs. Its throwing the 1249 code and one thread said check for vacuum with a vacuum gauge. I plugged it in where the red hose was plugged into at the waste gate and even when reving it we get no vacuum. Am I doing it right?

 

I think that would be pressure, as it pushes on the waste gate actuator. The rod is pushed out.

 

So what does that mean?

 

You said you were testing at that point for vacuum. There is no vacuum there.
The waste gate is opened by pressure acting on the actuator which is where you removed the red line. If you remove the E clip and arm to the waste gate you could see
if the waste gate moves freely. its just a flapper in the turbin housing, but I don't think
that would be the problem. look over the whole system for the usual boost leaks, boots,
up pipes etc. Look at all the sensors and wires. Sounds like boost leak but I'm no mechanic. If I'm wrong others will give you the right answers, but check everything you can see. Maybe somethig easy. 1249 says steady state failure, ground short, plugged hose/port, solenoid/actuator. Look at those first. Try about 10lbs of pressure in the big head, the arm should move. make sure the red and green lines are clear with a little air.

 

He tested the rod and he said it does not move at all. What does that mean then the waste gate is bad?

 

Only if it's stuck in the open position. I disconnected my red line and plugged the red line, not the wastegate actuator. That red line will bleed boost when activated.

 

Which way is stuck open? I took the red line off and plugged it to the intercooler clamp

 

This has a photo of a closed wastegate.

 

If you applied a little air to the actuator, and the rod didn't move out, and it isn't in the position shown in the pic Tugly posted, then the actuator may be bad. Do you have the stock actuator? If so, switch them and you'll know. If not, remove the actuator, and wire the gate closed. Run a piece of wire from the gate arm to one of the bolt holes where the actuator was. If it runs right, then thats your problem. Takes a short time and costs nothing. Do you have a Banks actuator? I thought I saw that, might have been someone else.

 

Hey Tugly, I down loaded that 7.3 link and added it to my binder. Its pretty good. Just hope its all correct.

 

Is there anywhere a guy could get a manual like thatone that covers the whole engine? I have found little bits and pieces online but nothing anywhere near all inclusive.

 

I Didn't write it, but I've read through a number os items in there to fact-check. It matches everything I've read on the forum or in my Ford PC/ED book... plus some stuff I've learned from AE. I trust the info in there, but I invite others to scrutinize it as well.

Ya gotta dig deep... really deep. I found these on the web, but I'm having issues with uploading this morning. They are all for the 1999.

 

A friend of mine has a complete service manual for all super duties. Got them when he was in the Air Guard. Every truck is issued with one. If you know anybody in any service,you might be able to get one. He told me they just pile up and after a while they get rid of some.

 

You have just secured a place on my most favorite persons list. I was able you download all of the pdf files except for the first one. I couldn't find the trouble shooting pdf anywhere. Would you possibly have a link I could follow for that one? Thanks again brother it is much appreciated.

Thank you so much for the information. I am pretty mechanically inclinded perse lol. But not with computers. May i ask where I can find these downloads you listed? I am having so many issues with my 99 F350 7.3L that i am struggeling to iron out.

If you could help i sure would appreciate
Thanks
