Question about 2004 GMC Yukon

1 Answer

2004 gm yukon wont crank.

2004 gmc yukon will not start when there is 1/4 tank or less and sits for several hours. after adding several gallons of gas it cranks. today it cut-off for the first time and acts like its out of gas. fuel pump is coming on when switch is turned and purged the lines up front and they seemed to be getting a good flow of gas.

It is not necessarily the flow of gas that is important. You need at least 40 pounds of pressure for the injectors to operate correctly.

SOURCE: 95 gmc cranks but wont start

To run it must get gas and spark from the plugs. Since you say it does start when pouring gas down it then it seems spark and plugs is not part of the problem...so...you are back to it not getting gas....so...something is amiss with the gas supply....fuel pump, filter (which you said are good...how do you know that for sure)....or...possibly look at the gas itself......has the vehicle been sitting for a long time with very low level of gas in the tank...if so then water can condense in the tank and you might be pumping water to the engine....so...dump a bottle of stuff in the tank that gets rid of water...available at any gas station or auto supply ... contains methonal...which will absorb the water and allow it to be burned in the engine. Still...I doubt that is the problem but it is cheap ($1 to $2) and will not hurt to try. You might actually be flooding the engine with gas by the way you try to start it. I suggest you let it sit for 30 minutes or so....then retry starting it. Use the procedure of NOT pumping the gas pedal but instead slowly push the pedal to the floor and hold it there not moving you foot and then crank the engine until it starts...but not more than 30 seconds at a time with rests in between of at least a few minutes to prevent starter overheat and damage to it. If you had been flooding the engine then this procedure should clear out the flooding and allow it to start. Also, if, as mentioned, the level of gas in the tank is lmost empty then put a little more gas in the tank. Somehow it seems you may not be getting gas or if you are then it is been flooded and will not start. I hope the procedure helps some.

SOURCE: 04 GMC Yukon won't start on less than 1/4 tank of gas

have your evaporative emission control system check.sound like you have purge valve solenoid not working or vent valve control solenoid.have it scan.to see which component not working..reason your gas tank expanding. your fuel vapor building up pressure.your purge valve and vent valve open allowing gas vapor from charcoil canister. to be burn in the intake manifold to be burn in combustion chamber.

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.

My car ran out of gas, now it will not start


If high miles, it may be a fuel pump. Fuel pumps usually go when gasoline is low and pump gets too warm. This may mimic running out of gas when there is a gallon or two of gas still left to draw but needle reads empty. Have someone put their ear to the gas tank while you turn on the ignition switch. the pump should run for 2-10 seconds with key on and not cranking.

If you don't hear the pump run, then investigate further for a failed pump.

2003 yukon xl turns over fine wont start.


Someone will need to figure out if you are lacking fuel to the injectors or spark to the plugs to proceed.
You say the pump is fine, have you checked the fuel pressure, and do you know if the injectors are getting voltage and ground pulse from the computer ?

2009 chevy aveo ran out of gas now it wont crank


No crank to a mechanic means the starter motor doesn't spin the engine over, is this what you mean? Or do you mean the engine cranks over but will not fire up and run? If it is the latter have you added at least 3 gallons of gas to the tank to make sure the electric fuel pump inside the tank can properly prime? If not do that, also you can spray starting fluid into the engine engine air intake pipe after adding the 3 gallons and see if that gets it going. If it still will not start you have burned up the fuel pump and you will need to drop the fuel tank and replace the pump, remember the pump is cooled and lubricated by the gasoline it runs in, so when you run low on fuel or out you can very quickly severely damage the small electric fuel pump. Never let the gas gauge level go below 1/8 tank to prevent premature fuel pump failure.
