This morning I started my truck and it idled very rough and sounded as loud as a Powerstroke. The service engine light soon came on and I turned it off after running 2 or 3 minutes. I waited about 10 minutes then started it again to move it back into the garage as I was afraid it would damage the engine to drive it this way. It ran fine with the service engine light still on, so I drove it to town and warmed it up. (outside temp 35f). It ran fine and the check engine light went off. I tried to drain any water from the fuel filter and nothing, not even fuel came out. I changed the filter about 10k ago. Edited by: Walter

Hmm, I would have the code pulled to see what set. Thats the first place to go and once we get the code, we can move on from there. I would also start planning a time to change that filter. 10k is the max I like to run them.. Since it cleared up, I have to wonder if you had some goofy fuel there. You will have to crack the bleeder in most cases to get anything to drain from the water seperator

What do you mean, "crack the bleeder"? I opened the bleeder until it felt like it would fall out and got nothing from the filter. My dealer says 1 to 2 hours to pull the code. this seems ridiculous. I do plan to change the filter tomorrow. The last time I changed it, it took about 1 hr. and some skinned knuckels. Wish Chevy would have put it in an easier spot to get to. I really apprecitate the help. Thanks

When you open the water drain on the bottom, loosen the bleeder screw on the top of the filter. Take the truck to Autozone and have them pull the codes. Walter, check out my article on changing the filter for some easy steps to doing it

Thanks a lot Eric, I think this will help a lot and I think this is the greatest website, I have ever seen. I am very new to this site and must read some of the other info and get familiar with it. I purchased a NAPA filter and hope it is good quality.


Thanks again,


Walt

Walt, you will have no problem with the Napa filter
