BUT WHEN THEY ASKED WHEN THE LAST TIME I CHANGED THE SPARK PLUGS I TOLD THEM TO STOP TOUCHING MY TRUCK! so my older brother has it at his house now and im going to get it this friday ... but the truck has loss of power and blows black smoke stock and will stall out and wont start for at-least 20 min then its good to go for a bit then dose it all over.I replaced lift pump. but maybe some one has some in put
thanks pleas help

 

Dead turbo, cracked intercooler? I lost an intercooler boot on the highway once and the truck fell on its face blowing smoke all over the place..

 

put a boost gauge on it and check your boost also see if you can get any codes. also check your injectors

 

ok thanks for the in putt yall. ill keep yall up dated after i get dun hauling it back from california any one else with any ideas i would appreciate it thank yall.

 

Wide open throttle with lots of black smoke and loss of power is an air flow/restriction problem. Check your air filter, intake tubes, and all boost tube boots and clamp connections. Check for torn boots and cracks in the tubes and CAC.

 

i would look at the boots too. or the plastic pipe on the intercooler from the turbo sometimes break

 

Sounds like a blown plastic intercooler. Boost gauge time.

 

ok i hope thats it rather the turbo or injectors.. but i really wont know tell i get to california this sat and look at it. all be for i putt it on the trailer and drag it home to texas. and maybe fined the problem with what info yall have gave me. but either way its going home on the trailer cuz that wonder full thing we call diesel is not getting any cheaper lol

 

isnt the 05 the one with the plastic intercooler sides

 

I don't think its a turbo or turbo boost problem if you are having a black smoke problem. Loose of power yes, but black smoke no. You need turbo boost in order for for fuel pressure. I think your problem is the fuel rail high pressure switch. These have been a problem check for corrosion at the switch connector and make sure your connector is connected properly, if that looks ok then its probably the switch and you have to buy the fuel rail along with the switch as cummins has changed it. You can verify this with a low pressure code.

 

when i blew the intercooler hose on my 98.5 it blew a ton of black under throttle. usaully if its a pressure issue idle and crankinking are effected

 

well im not positive on the plastic intercooler. have not really ever payed attention to it to be honest. but il fined out.. and yes the truck will idle fine and crank form what i know it was when i told the dealer to stop working on my truck. but its at my brothers house now has been for the last month just siting in the yard

thanks for the info

 

O and i know its not the turbo cuz when i was driving i thought the same. at first. but could here it spooling good still cuz i took the silencer ring out like 20k miles ago

 

early 05's had the plastic intercooler.. I'm still living on borrowed time with mine..


Also, with a blown intercooler boot it will still blow black smoke.. Dont ask how I know.

 

yes i blew a boot on my old one and lets just say it filled the bed with smoke and then it rolled out of the back at 60 mph
