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 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.
