got in my truck today...had no ***** at all..looked at my gauge and seen that i had no boost? just got my turbo rebuilt two months ago...after looking around at all the ic connections and feeling for leaks i noticed that there was a whole in the y that was blowing out pressure...looked below it and seen that a vacuum line of some sort had popped out...so i plugged it back in and now have boost....does this happen alot?

 

Sounds like your MAP line had come off... What are you using for a boost gauge?

If it was your map line, more then likely you had two issues, your boost gauge was not getting any pressure (even thou your truck would be making some with that little of a boost leak) and your MAP sensor was reading nothing, not allowing the PCM to fuel the truck properly.

 

yeah it ran to the map sensor..and i have a isspro gauge
