i have an 06 cummins 2500 4x4 was traveling down interstate and truck started running rough. checked codes and found fuel delivery and group a circuit open. changed valve cover gasket and fuel filter still same problem. 1 2 & 3 injectors not working any help

 

common rail people please chime in

 

actaul code numbers would help

 

Codes p0148 and p2146. Ohmed injectors all were 1 ohm except number 2 128.46. !_( dealer did injector kill and said 1 2 3. Made no difference on running. 4 5 6 made a difference when killed

 

replace #2 injector....starting to see this problem more latly...seen 3 trucks (4 injectors) with the same problem in the last month...a bad injector kills all 3 on that circuit....you can clear the code and it will run right for a couple min then drop that whole circuit again

 

sorr y i never got around to opening my alldata up to look he codes up....did u figure it out yet or do u still need assistance

 

Yea got it fixed. Dealer couldn't find it. Found #2 injector bad.
