Diesel Fuel System problem #1

2003 Chevrolet silverado. Consumer writes in regards to fuel injectors problem . The consumer stated his vehicle was always mis-diagnosed. The dealer never checked to see if there was a problem with the fuel injectors, in which white some was emitting from the vehicle. The dealer only replaced the glow plugs, which was not the problem.

Diesel Fuel System problem #2

I was driving down the road at highway speed (65mph) and the front right steel brake line burst and I lost most of my brake fluid. Upon looking under the truck for the cause of the problem, I noticed that all of the brake lines and two of the fuel lines were badly corroded. I tow trailers often and I'm thankful I wasn't towing our 11,000lb 5th wheen camper when this happened or there would have been a horrific crash! I have done quite a bit of research and noticed that there are quite a few compliants about the same problem for this model year pickup. Is there a recall and how do I go about getting this fixed? I am out of work on medical leave and cannot afford to take the truck to the shop and "wait" for gm to think about re-embursing me.

Diesel Fuel System problem #3

Chronic failure of fuel injectors on 2003 duramax chevy truck, deal has replaced injectors three times, now they are failing again and want 5k to fix them. Last fix was 40,000 miles ago. Here is the short and skinny. I was informed (during an injector swap in my truck) that the different types of injectors that were tested by gm and their partners (isuzu and bosch) provided good data for the ongoing service campaign, but will not be released through gm parts. Gm and partners (bosch) have made 2 modifications (documented) to the injector design from original and has deemed the current incarnation of this injector adequate. That is gm's solution apparently. Will it be a permanent solution? who can say, but it probably will be the only solution we ever see. The production and design cost combined with a "limited" customer base dictates that we will probably not see a complete replacement unit of new design come into the marketplace. Many failure causes have been theorized, two main modes of premature failure have emerged, but I am of the thought that a waveform analysis of the power to the injectors done over long term might yield some interesting results. Having been through the mill on these injectors personally, and having read volumes of information, I feel very strongly that we are loooking at the effect of a problem on a weak point (injector bodies), and not the root cause. So the buy is stuck with a poorly engineered truck. What recourse do we have??? come on gm come clean and do what is right, after all we the people bailed you out!.

Diesel Fuel System problem #4

No incident yet.

Diesel Fuel System problem #5

Fuel injector failure.

Diesel Fuel System problem #6

Instrument cluster fuel gauge failure. This happens frequently, sometimes every day. Nothing has been found to correct the failure. The fuel gauge often shows inaccurate fuel level readings. It happens more often when the car is warm than when it is cold. It happens a lot when the car is hot (e. G. Heater is on very high or in the summer). I'm afraid that the fuel gauge will tell me that I have more fuel than I really do and, as a result, cause the engine to stall from fuel exhaustion on a busy highway resulting in an accident. This still happens to the vehicle often. Repairs have not been done. I have heard that many many others with this make of vehicle have the same problem. The same issue happens not only to the fuel gauge, but also these other gauges: the speedometer (which could cause me to drive too fast for conditions or break the speed limit), oil pressure, engine temp, voltmeter, transmission temp and tachometer.

Diesel Fuel System problem #7

Fuel injectors replaced all 8 injectors at 34901 miles, again at 85039, and again at 141,000 and now again at 185,000.
