it could just be bad gas passing through or an early indicator of a failed catalytic converter specially if there is a rotten egg smell in the black smoke
May have sucked up sedement from the bottem of the fuletank. Try blowing out fule line with compressed air. If it is clear and problem persists, change fule pump
sounds like a fuel regulator or fule pump. your going to have to test the fuel pressure the port to hook a pressure tester is on the fuel rail. anything below 35-40psi you will need to prob replace regulator
Well I have a 2002. I have had this prob from the day I drove it home from the dealer. Evry time I'd put fule in the rear tank the guage stopped working. The transfer pump stopped working. It was back at chevy (3) times, and still no fix. They keep puting in new rear transfer pumps in it but that is not doing it.
It is an Electrical Problem, I keep geting rear transfer pump codes. So I was just unhooking the bat's but it's a pain.
So I just stopped puting fuel in the rear tank. And now if it stops working I just us the scanner to clear the codes and it will start to work... I am so done with this truck.
This truck also had ( whater pump, (2) Glow plugs, Injectors, fan cluch,) all go out in the first (5) years. GM, Is trash...
Souds like you need to replace the SPI unit (the spider). Also make sure you have the proper fuel pressure, otherwise it will not open the poppets on the SPI unit. I think Min pressure is 60 psi.
