P-Pumping a 24V Cummins
 

i cummins is dieing... have the code 1683 meaning no comunication between the Pump and the Ecm... no knowing how to fix this i just kept driving my truck... my truck barly runs now... i don't know how to fix this but i do know if i replace the pump and its the computer i'll be pissed and just back words so i am thinking of running the old p-pump this way i know i'll fix the problem! anyone have any ideas on this or some good post for me to read that would be great... or maybe a way to diagnos my truck to tell what is broke...

if i could get some quotes on some convertion kits as well that would be great

Id say your vp and lift pump are dead. Your can fix that for around 1550 with a new vp and a fass or airdog 150. However if you want to a p-pump swap your looking over 3k in just parts. But P1683 is a speed control code. Did you mean 1688?

you can get a 215hp p pump from merchant automotive remanufactured for $400, Crazy carls.com has entire kit with out the pump for $1700

I thought merchant only did duramax parts?

sorry the codes i have are
1693 ecm code
1689 no comunication betweem pump and ecm
0237 low boost(vgt turbo is stuck all the way open)
to further this when i drive my truck will not build past 1400 rmp... if i clear the codes my truck runs great. intill the code come back. i thought that it would be my injection pump, but if it were i would think when i cleared the codes it would still run like shit.. however that is not the case. when i clear the codes my truck runs great with full power. then the codes come back and it will barly idel. it sputters arund trying to keep itsself alive. and when i go down the road i have no power and the rpm stop at 1400.. any suggtions? is it a bad ecm? or a bad ground somewere?

good news i fixed the problem. i had a pig tail from fleece for my vgt controler pluged into my data link. on the back side of the pgi tail was my adrenaline and my vgt controler. i have removed the vgt controler and the truck run great again with no codes. no i just hope fleece will help me out with there product.
