no previous work done on the vehicle except the regular oil and filters(oil, air, fuel) replacement. it was a surplus unit and running for 2 years now. the problem occured last week. Your problem seems to be fuel related. Keep us posted as your experience may help other Tsikoters.

thank you sir You're welcome.
sir DD,

still on the process of consuming the previous diesel fuel. about 3/4 fuel left as of this writing as the vehicle is not usually used. on the average, about once a week. could this frequency of use contribute to the problem as the injection pump is not usually "exercised and lubricated" by diesel?

to add up some info. with the truck not running (engine on), blipping the throttle produces a combination of severely white and not so severe black smoke with the engine running roughly.

thank you sir.
