The truck lost all power today after re starting after a ten minute break. It has hardly any power and belches TONS of grey smoke. It will not raise above 2000 RPM even with it floored.
I drove for about an hour this morning with no problems. Then it started.
Thought it might have been bad fuel but i had already burned over three quarters of this tank before the problem surfaced.

No check enging lights. No water in fuel lights. Oil pressure good. No boost leaks. I'm lost.

It'll quit after a while and drive normally and then out of nowhere it starts acting up again.

ANY help would be great. Tnanks guys

could it be gelling up on you. How cold is it there???

 

it was in the thirtys today. the last few days i've been in the hells where it was below zero for most of the day and didn't have any problems then.

 

whens the last time u changed your fuel filter?

 

Thats what I was gonna ask as well....

 

pulled codes and came up with the following:

P1682 -
Manufacturer controll ????

P0122 -
TPS/ Pedel position sensor

P1693-
Manufacturer controll ( pointless code from what i've heard)

P0234 -
engine overboost condition.


Could the Throttle position sensor cause all the smoke??
No VP44 death codes so far.


Fuel filter changed about five thousand ago.

 

Well after half a day of assesment found out the stock Carter Transfer pump took a dive. I belive the only thing that saved me was the aftermarket in line Holly blue pusher pump i installed last summer.

the two weird codes were charging system low voltage and a code that says that codes have been thrown before.

the Throttle possition sensor low voltage code was fixxed when i re-adjusted the APPS back to required voltage of .503 VDC.

hope my hard lessons help others later on donw the road.

thanks
