Hello I am new here http://www.dieselplace.com/forum/smileys/Hug.gif, but I like this site. I have a problem with a truck I have in the shop. It is a 91' Chevy truck with the 6.2 L.......anyway this thing starts just fine but at full throttle this thing runs like crap! It has a stall, and emits alot of smoke. It does not show any codes. So far I replaced the fuel filter and the rail pump. PLEASE IF ANYONE HAS A CLUE.


Thanks,

Have you even bothered to check the injectors? How many miles are on it?

Air filter????

advance piston is worn out inside the pump, time for a rebuild.
