New To Diesels Need Help Please.
I have a 2001 dodge ram 2500 turbo diesel. The other night I was driving the check engine light came on and the truck died. It would turn over but would not start. I read the codes using the key method and got p1693 and i used a scan tool and got p1688 can anyone help me understand what these mean and where to go from here any help is very much appreciated.

First things first.
Disconnect the EZ. Make sure that's not the issue. Shouldn't be, but checking is free. Check your fuel pressure at one of the test ports in the system. Even though you may have good pressure, you could have a roasted VP.
A fuel pressure gauge should have come standard on the VP44 trucks.

on the vp test port how much pressure should I be getting? If the pump is not primed will i still get a reading on the test port on the vp?

is it possible to rebuild the vp? If so where can I purchase a rebuild kit? I seen one on ebay but have no idea if it is right also could it be the fpcm that is bad? I appreciate and thank all of you for your input and information it has been very helpful and I would be very thankful for more input and information.
