I have a 2006 Silverado Duramax LBZ. This morning I started the truck and 30 seconds later it stopped and wont start again. My bad, I have had the "fuel filter needs replacing" message on for quite some time now and my guess is that it's the reason. I can do alot mechanically but the sensor connection (on the bottom of the fuel filter) to the wire harness is not pulling apart - is there some trick to disconnect?

Thanks guys!
 
take a look at the WIF sensor in the pic... the red arrow shows where the clip built into the plug is, and what it looks like...
the yellow arrow shows what direction you need to pry it to get it to release while pulling on the plug to separate it from the other...you can use a small screwdriver a pic tool or even your finger nail to pry as you are pulling it apart

Thanks Pepperidge. Do I need to put in any additives to the fuel to clean the system out since the filter stayed on too long? Does dirty fuel by-pass the filter if it reaches maximum?
I also watched the mileage drop recently (was consistant at 17.5 and recently was 14.5 mpg) can a clogged filter do this?
 
Winter Diesel will cause your fuel economy to drop, so will the longer idle times that we all use to get the motor and interior warmed up.

DieselCash was right about winter blend decreasing MPG...

but nothing should be getting past the filter ...theoretically it should just become plugged and no longer allow the vehicle to run...filters have been known to blowout on rare occasion, but if that had happened you'd have a lot worse problems than a clogged filter...the filter media and dirt would pass on to the injector lines and injectors causing injector damage and a big repair bill...
 
Welcome to the forum! :welcome2:

It is always a good idea to run some Stanadyne or Power Service White in with your fuel in the winter time. Stanadyne and Power Service Grey in the warmer months. I feel that it keeps the injectors cleaner, so they fire better and more efficiently. I run fuel supplement in every tank.

Just a little tip, when you remove the fuel filter, be sure that the old rubber gasket/O-ring comes off with it. Make sure the new filter has the new rubber installed in it. When changing the WIF sensor, be sure not to over-tighten it, as it can crack and cause a fuel prime issue. Some members on here have even plugged it off with a cap, and do not use the WIF sensor, as it is proven to be not that reliable. If you go that route, it is OK to just leave the wires off or unplugged, as you should not get any codes from it being unplugged. Just tape the wire up with a little electrical tape. And be sure to change the fuel filter within 7500 to 10000 miles. It is not good to go over that with an OEM filter. Keep the fluids good and clean, and you should be all set. :thumbsup:
 
I actually had to pinch down not pry up on the clip retainer for removing the WIF wire. Now I need to figure a way to loop around the filter strap. There is about 20 plastic clips holding the wheel well shroud in place, I'm tempted to cut a slit and get my hand inside to turn the filter. I have come to believe this is not a job for a woman!

Unless you are a women with large man hands, than working on trucks would be perfect.

More than once I wish my hand was just a tad smaller to get into some nook or cranny.

Those plastic clips come out easy.

I am sure a duramax owner will pipe in here soon enough to give better advise than me.
 
you can remove the passenger side battery[just disconect the front drivers side battery too] this will give you more room and you can stand on the battery to raise up higher over the fender too,,theres a black plastic bleeder screw on the top of the filter housing ,.remove it and push the 1 1/2'' diam metal plunger on the filter head 3-4 times till fuel comes out to prime filter too[just go slow and you won't make as much of a mess],,then snug the bleeder back down,i always dump some hot water on the filter head when im done so i dont smell diesel after i drive it,,fire engine up and let it run for a minute ,,then your done
 
they make plastic strap wrenchs thet will go around the filter ,any auto parts store or walmart should have them,,ive done filters on the side of the road ,not hard,just messy,,,and if you can drive a duramax you can fix one too
 
What I do is let the screws and the pop in clips out of the left side of the liner, just enough to pull it from the fender well and get my hand in there to loosen the filter. I've found this is the easiest way for me to do it.

I finally finished. The battery had to come out so I could get that square bar with strap around the filter. I was getting worried because the filter started to crush. The new filter is plastic so I didn't use the strap wrench to put it back on, just tightened as much as I could by hand (I had to lay across the top of the motor from the driver's side, would have made a funny picture). It was a work-out. Does anybody know what a shop charges for this?
 
A shop would charge too much! You just saved yourself a lot of money. And you gained experience, so the next time you need to change it, you will do it in half the time. Did you prime it and start the truck? Did it stay running? Just beware of the plastic filters. There is a good thread in the maintenance section regarding the plastic filter.

I hope this filter doesn't fail before I can change it in the spring when it's warmer out. This plastic filter was the only one I could get quickly on a Sunday and not travel far. I primed/pumped until I could feel the pressure. I took a ride with truck for about 10 miles. I noticed the average mpg is really low now but the hesitation is gone.
