I have a 2001 2500 5.9 td.was going down the road to pass someone truck shut off and check engine light came on.pulled over turned key off and started truck up,now it will idle but when i press the accelerator,truck wont rev up and it sounds like all the injectors arent working and sounds like a gas motor not firing on all cyinders.I have an edge with additude,i unplugged it from the map sensorback to stockand still no difference.I got a list of codes from odometer; P1693,P1688,P0251,P0252,P0253. Thanks in advance for any help.

Probably a fuel pump. Hope it's not the VP44...

 

1688 is VP pump internal controller failure, sorry, probable IP pump time.

 

Check out blue chip diesel, they have a pretty good info page on the VP 44.

 

What's yer lift pump fuel pressure?
