1998 GMC Yukon. It has trouble starting once it starts it runs great

Eliminating the obvious, do NOT put your foot anywhere near the accelerator AT ALL when starting the vehicle (some people actually stomp on the accelerator while starting their vehicle, then wonder why their vehicle won't start when cold).
You may be losing pressure at the fuel rail when the truck is off. Either you have a fuel leak (such as a leaky fuel injector or leak in a fuel line), or you have a bad fuel pressure regulator. Try turning the key to ON, leave it there for ten seconds, then start the vehicle. If the vehicle starts more easily, you are losing fuel pressure when the vehicle is off.
It is also possible that the check valve in your fuel pump assembly is leaking pressure back into the tank. Additionally, as a last measure, replace all fuel in the vehicle to eliminate the possibility of fuel contamination or moisture build-up. Avoid using ethanol blend fuels in your vehicle, if possible.

My 2002 GMC Yukon 5.3 Ltd flex fuel won't crank if it's low on gas and on a hill. This was happening when I first purchased the truck from Carmax. They said nothing was wrong but now anytime it low it...

Fuel pump or ? pump relay, or lots of dirt at Buttom of tank. My money is on the relay. A clogged filter could cause this but then it would happen all the time. If your going to keep this vehicle for a few more years I would replace pump, relay and filter. Then I would purchase fuel injector cleaner and put a bottle in once a month.

Do you have a picture of a 2002 gmc yukon fuel filter?

This particular filter is just an example of the fuel filter for an '02 GMC Yukon XL. The link I've provided is specifically for regular unleaded fuel. If your Yukon is a "Flex Fuel" (can use either unleaded or E85 gasoline) the specific filter/part number will be different. Otherwise the filter itself looks exactly the same. And if you're not certain, the filter should be located along the driver side inner frame rail...below the driver's seat.
Good luck

Fuel lines in 2004 gmc Yukon froze. How do I get it to start again

Put some gas in it before you ruin the fuel pump. That is step #1.
Next, try running a heat gun or hair dryer over the fuel lines from one end to the other, if you suspect the fuel lines are frozen.
Hopefully that will be enough to get it going.

i had the exact same thing happen to me with my first car, a 1966 mercury comet.

i replaced the fuel pump, rebuilt the carburetor (twice), and finally rebuilt the entire engine! still, every time afterwards, the car ran ok, then would cut off again!

it turned to be just a $2 clogged fuel filter. i' suspect the same with your vehicle. after removing the filter, simply blow through it. any resistance, means it needs replacing.

Check the fuel cap!! If the vacuum relief is not working it can impede the fuel flow and cause the engine to shut down or not restart after a stop. Waiting usually gives things a chance to stabalize and the engine will restsrt. When this happens again try loosening the cap and see if the engine will restart.....If it restarts immediately, REPLACE the fuel cap..Do Not leave it loose because this will cause other problems. If it is not the fuel cap the problem may be the filter, the fuel pump, or aome other fuel system malfunction.

Vehicle chokes, sputters, and then shuts off

Start with the simple and replace the fuel filter. The fuel filter may have reached the end of it's life time and is dirty causing the issues you have. The worst is the fuel pump it self has gone bad and needs to be replaced, the fuel pump should be producing 62 to 65 PSI when the engine is started and should drop no more then 5 PSI when the engine is running. You can check the fuel pressure at the shredder valve with a fuel pressure gauge. Good luck and keep me posted, be glad to help get your Yukon running 100% again.

Car started running slower until it completly stopped

Sounds very possible but it also sounds very expensive for a simple fuel pump? He must be on a good rate. In Australia it would cost about 4-5 hundred for that repair at MOST and the US dollar is nearly worth twice ours! *Shock*
