6.5L missfire and LOTS of white smoke...

[Mr. Bob]

Well, back at it guys and need your help!!!!

Same 1994 C3500 I posted about a while ago is acting up again...

At idle the truck runs fine, idles smooth, and no smoke. If you rev the truck up to 1800ish ( not driving ) or try and drive the truck, it starts to feel like an engine miss-fire and puffs white smoke like crazy!!! Smells like a rich diesel smell not antifreeze.

Feels almost like an injector going bad, but also have my doubts about the injection pump....

Truck has 180 000 miles on it, have no previous history on injectors and IP,

Did the electric fuel pump and filter 3000 miles ago....

PLEASE HELP!!!!
Bob

refresh my memory...
is there any Borg implants growing out the side of the IP?
if there is, I can't help you much. there's other guys who lurk the chebby section who can.

SES codes?

 

[Mr. Bob]

I spent very few minutes looking at it today... There was no SES light on, and I quickly hooked up a scan tool to it, but could not get communication....

Does a paper clip in the data link connector work on these trucks???

 

[chrisk1500]

Yes....paperclip will work when jumping A and B

 

[Mr. Bob]

Well, I guess I will pull the codes and see....

Are these known for injector or IP failure????

Injectors are recomended to be replaced at 100,000 miles. I dont think this is the problem but it wouldnt hurt to change them sometime. I would be pretty suprised if that is the original IP on there yet. IIRC the first ones were more prone to failure but then have been updated, is there a green tag on top of it? Hook up a scan tool and look at the timing DES and ACT.
