Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
My first guess is that there is an excessive amount of debris in the fuel tank. Now, even with new filters, the smaller particles can pass right through and result in a plugged injector. If it is possible I would drain the fuel, into a clean container of some sort, using the plug in the bottom of the tank. If it has one. And then thoroughly flush the tank out. If it does have a plug in the bottom, you can use a garden hose with water to flush it, just make sure you allow it to dry COMPLETELY before refilling it with diesel. And if you do find alot of debris (rust, dirt, etc.) even after you flush it out it will take a while for the injectors to clean up and run right. Hopefully they haven't become damaged.
Hope this helps.... Let me know, please.....
