i have a 02 6.6 duramax i just replaced all the injectors and now the truck will not start, cranks real fast i probed the wires at the fuel tank and found that there is no power getting to the fuel pump i checked the fuses and relays all are fine, is there any way that having the batt disconnected for 2 weeks would cause any of these problems. the injector pump under the intake comes on and everything in the truck works, any help would be great thanks, also no codes are presant.

there is not fuel pump in the tank. open the bleed screw and pump up the primer until fuel comes out. if that doesnt work leave the bleed screw open and crank the truck

there is a plug going to the tank just like a gasoline car has i was thinking this was a in tank pump guess i was wrong, i am getting fuel to the filter and to the fuel rail, the truck just wont start, is there a way that maybe the passlock system is keeping the injectors from cycling.

i had a problem kinda like that check this out it may help Emergency Relearn on ECM works on LBZ - Duramax Diesels Forum

 

[brown bear]

it says that works on lbz but also it did work on my lb7
i had the same P1630 code

if that doesnt work leave the bleed screw open and crank the truck

Why would you do this? The CP3 sucks fuel from the tank and if the bleed screw is opened and the truck cranked over it will suck air through the bleeder and not the tank. Am I missing something?

Correct... that would suck air.

Try a spare key... pass lock may not like the key your using.
