No Power!!
 

Hi i have a 2001 cummins and the other day i drove it and parked it for a couple hours and then went to drive it again and it didnt have any acceloration at all. It seems like it wouldnt be getting enough fuel. I replaced the fuel filter and it still dosent have the same power, it is so doggy all through the rpm range, any help would be great thanks:humm:
