Hi, i have seen this problem ten years ago twice, but i was dumbfounded by the answer. all details aside, I replaced the ecm, and never had the problem again with both of them. this repair was a recommended repair by the local truck depot in my town, they stated the ecm got hot along with the truck and it lost the injector sensor signal. now, don't take this solution and run with it, i haven't repaired a 6.2 diesel in ten years and i maybe off track completely. but at least maybe you could ask around your town or maybe a large truck facility about this. of course, you should take to a shop to have diagnosed. hope i could help.

1999 gmc sierra 2500 6 liter ran out of gas now won't start


If you are at or near the 100,000 mile mark then your fuel pump may have failed. If you remove the fuel filler cap and listen carefully at the filler neck while someone turns the ignition key to "run" [don't actually crank the engine] you should be able to hear the fuel pump buzz for about a second and a half as the key is turned On. If you don't hear the pump buzz then odds are your pump is dead. Your pump may have actually failed making it appear as though you ran out of fuel. Not to uncommon. Hope this helps and good luck!

I have a 1989 GMC sierra 4.3 Liter, fuel pressure


u can do the check the other way around/ disconnect the fuel line that supply the injectors/ put the pipe in a small plastic container to see if fuel is being supplied by the pump and avoid fuel spill in ur engine/ crank the engine for at least 5 seconds see if the fuel squirts with pressure/ if it does then ur fuel pump is ok / blockage is somewhere down the fuel line/ u can check fuel lines by blowing it with air but u gonna need the help of an air compressor.....

Excessive black exhaust on 2003 GMC Sierra Duramax Diesel.


This is what i would try (cheapest first) redexe/wyyns
injector cleaner,double dose,then i have put 1gal gas in 10gal diesel to increase burn temp (you may encounter a hot start problem temporarilly)then if still smoking, get a compresion check on the engine(this will tell you volumes)
by the way the NATO tanks put in 1/3 gas in diesel to stop it freezing in arctic conditions.any more than 1/3 can result in problems.
