Fuel filter Help

[Devious02]

Okay, my truck at start up will idel like it wants to die out spark pulgs
and wires have been changed in summer. I cleaned out the trottle but
it stil is doing it. Could someone help with step by step of how to
change fuel filter do I just take it off will it leak gas? ?
What els could be causing this when the truck is warm and
I go to the store or whatever it will start and run fine.. I could
hear the fuel pump spray when key is turned so I don't think
it's that no check light on.. How about seafoam? 2002 Yukon 5.3 4x4

the filter will leak a little fuel as well as the lines. not a heck of alot. just remove it and reinstall the new one. pretty straight up process. its on the drivers side inside chassis. i didnt even remove the bracket. just slid the old one out and new one in. when you go to start the truck the first time with the new filter let it prime a couple times since all the pressure will be removed from the system.

Okay, Thanks so all the talk about depressurizing the fuel Lines before removal you don’t have to?

Do I really Need to get that or can I use the tools I have?

lol...all you need is 2 wrenches (5/8 & 3/4 iirc), plus a socket/ratchet (13mm?) for the filter mount. Depressurize the fuel lines from the schrader valve on the intake.

Okay, well changed the filter very easy. But still has a hard start. Any one have any advice? Map sensor maybe?

Seafoam it. How many miles?

 

[03_Denali]

If it only does it when the engine is cold, I would suspect the intake gaskets.

try the fuel pressure regulator if its hard to start. might be making the plugs wet.

If you have a leaking injector when closed, yeah.
