after changing the injection pump and running the truck for a bit it will not start back up. alrdy took it apart again and made sure the lines were tight and bledd the fuel system twice. still sucking air somewhere. need help if anyone has any ideas.

 

ok goin thru this in my head the only things you had apart that would keep it from starting would be the fuel lines and the wiring which it sounds like you have allready checked...i'm wondering if possibly the shaft on the cp3 is slipping inside the gear since its kinda hard to tighten it down real good without making a fixture...do you have any way of checking live data on it? where you can see whats going on with the rail pressure so that you can see if that is the case without taking it back apart?....or are you sure your still getting air like because your getting air at the bleeding screw?....also the ecm could be in an unstable state since you had the wiring apart....take the battery cables off and touch them together for a min of 30sec to reboot it

 

im no expert but my 01 dun
similar mine turned out to be a cracked water sensor on
the fuel filter

 

yeah there are several places on the filter and filter housing that one could have an air leak but unless he changed the filter just because then he wouldnt have had any of those parts off changing the CP3

 

i got it thanks

 

what was the solution?

 

does anyone know anything about a p0093 code my truck throws it under a load

 

1093?...0093 dosnt come up but 0090 is a fuel reg code....1093 is a low rail pressure during power enrichment code...means your commanded rail pressure and your actual rail pressure are too far apart

 

my scanner read p0093 the engine goes it into limp mode i dont know guess i will take it an get it checked out i just know enough to get me in trouble

 

when its in limp mode will it only turn 2000 rpm?
