Chevrolet Silverado 2500 HD Fuel Injectors

(7 reports)
If truck sits at idle speeds smoke will start coming out of tail pipe and get worse the longer it sits at idle. -
Truck was difficult to start. Dealer identified problem.GM injector pump disintigrated,contaminating the fuel rail and ruining injectors.$7000 to fix. After extensive negotiations, GM agreed to fix for $500 but only a 12mo/12000 mile warranty.(GM had recall but limited to 7 yr/100000mile ) My truck had only 50000 miles but was 7 1/2 yrs when entire fuel system failed so they did make an exception to cover it under a partial warranty. Now my 2003 with only 69000 miles is in the shop with a BLOWN TRANNY! GM refuses to assist with repairs dispite exceptionally low milage. The Allison tranny was reconfigured by GM and has problems with the extension housing breaking but you won't hear that from GM, but I did hear it from Allison. So here I sit with a 2500hd duramax diesel with only 69000 miles which already has had 2 major breakdowns due to GM's designs and total repair cost of $10000. BEWARE! GM added insult to injury by offering me $500 off the price af a new truck. -
I took my truck for a smog inspection and it failed!! The engine light had come on the previous month but then would turn off. I was told there was a malfunction in the glow plug and smoke from exhaust. I took the truck to a diesel shop which confirmed the glow plug malfunction and was also told the smoke was due to fuel injection system. The repair bill will be $5K, so haven't moved forward on having it fixed just yet. -
bad injector gm said i was out of warranty -
I was towing a fifth wheel across country and was in Nebraska in Feb very cold temps and blew my engine, it was determined that it was a possible fuel injector failure along with a rod failure, long story ended up replaceing engine -
Began this and it disappeared so trying again! 6 months ago started to have excessive exhaust smoke, especially at idle. Two GM dealers have said it is clearly an injector problem but no warrant coverage as check engine light is not on and required code does not reflect. GM knows this is an issue and extended warranty period by 100K or 1 year. This will runout in 2 weeks. GM dealer suggested putting fuel injector cleaner in gas and driving as much as possible in the hopes light would go on. This has not happened. We tow a 5th wheel each winter to are trying to decide if we should replace injectors (have been advised by other diesel mechanics to not use GM parts if we do this) or continue to drive and hope it continues to run. If we do that we are going to put signs in our rear windows letting others know that the smoke is from a GM failue that they refuse to fix, so they understand. Any suggestions - and where do we get the aftermarket injectors? -
