Question about 1992 GMC Sierra C3500

1 Answer

Two weeks ago i was driving my Sierra pick up deisel 6.5 liter and all of a sudden it felt like my turbo surged and and the engine quit. I was able to pull over and restart it after a few turns and it seemed to run ok. I was driving it again to get fuel on an empty tank and it quit again. I was able to start it and made it to the gas station. I filled up and went home. It drove good for a few days and yesterday it would not start. Now last week when it quit on me i was able to get it home and changed the fuek filter on the engine. When i looked at the filter it seemed to be a little milky so i replaced it with new part. It started again and drove for a few more days without a problem. Then it would not start again so after a few hours I cranked it over and it started ok and ran fine until a later evening time it started to feel like it was going to stall and like a fuel starvation problem but I was able to get it home. The next day i replaced the inline filter and it started again and drove it for a couple days and then it stalled again.....i restarted it and got it home and now there is where it sts. Im afraid to drive it till i know whats wrong with it,. Last year I had it tuned up and injectors cleaned so what could it possibly be. I think it may be a fuel tank with water in it or the injectors bad or glow plugs ....can you help me

Subaru legacy problems


To answer your question, yes they are liable for any damage as a result. Does your son have a heavy foot? If they are saying you need to pay for the repairs, find a good attorney, and he or she will go after them for attorney fees. I hate to suggest this but I am from the old school where I was taught to. CYA. cover yourself. Usually just the threat of legal action will result in a fair compromise.

Hi I have a Nissan Navara turbo deisel 2002 model it drives for approx 50 minutes country driving then dies, I wait for 1--2 minutes and it starts up and drives off as if nothing happened only to do i


2002 is common rail with all fancy electrics and computers and stuff like that ,now this makes it very difficult for this old fleet fitter who used to repair diesels with nothing more complicated than a vacumn controlled speed govenor ,where we used to re-calibrate the injector pump on the vehicle .I think this fault is either something simple like a plastic bag in the fuel tank that gets caught up in the pick up pipe ,failing which its a complicated electronic issue of which i confess to knowing nothing about

I have a 2004 F-250 with the 6 liter deisel. It is missing bad at start and black smoking. also had the oil changed three days ago and found new oil laying in the air filter and breather tube.


That motor should have a longer warranty on it I would take it to dealer, they are really bad for head gaskets and turbo chargers, if there is any damage that has been sent out the exhaust make sure they remove the nox convertor(looks like a cat. conv.) and clean it out or you will loose power!

Is this a normally aspirated diesel, or a turbo?
If its a normally aspirated, as most of the saloon/sedan models were, then there is nothing to be done. The engine outputs a whole 55kw and you suddenly start using 10 of them for air con...
If its the TD 70 or 90 then you may have a problem. The compressor does make a notable load on the engine, but should still be reasonably responsive. You could look into repacing the compressor, but that will be very costly. The aircon was a bolt-on for that engine, and is probably best to just accept if its cooling ok, then do nothing, or stop using it.
