Mechanic replaced 4 injectors on drivers side of engine. Turbo doesn't seem to be boosting. Truck sat for about a month and was fine when I parked it.. I am confused. Engine runs good but it takes a while to build up road speed. Any ideas? This truck has a 7.3 power stroke with no modification done.

 

can you hear the turbo trying to spool?

 

No. I see the blades turning and can barely hear it whistling. I also have a puddle if fuel in the valley of motor near the rear

 

most likely fuel pump is leaking or for some wierd reason the two fittings near the back of the head behind the turbo

 

I took it to a mechanic. This is over my head. Thanks for the help and I will check that fuel leak. Will the fuel leak keep the turbo from boosting??

 

yeah you need fuel to make boost

 

Ok thanks a lot you have been very helpful.

 

yup no problem
