My car sputters/stalls whenever I am at the 1/4 level remaining in gas..as if I am out of gas..once I fill up the car runs normal What could be the problem and how do I get the situation corrected?

THIS MEAN YOU NEED TO CHECK THE LEVEL SENSOR INSIDE THE GAS TANK MAYBE GIVES WRONG READING

Gas level sensors are very inaccurate, they become especially so over time. If you judge your gas level by your gauge reading - most probably by the time it shows 1/4 tank it is actually almost empty. When you make a right turn (or brake hard) the remaining gas in the tank rushes away from the gas pump intake. It usually means that you have about a gallon or less fuel left.
Solution: Set up your trip odometer every time you get your tank full, then read how many miles you traveled since your last fill up - you'd know how much gas you have left. Or replace your gas level sensor for a good new one. If you have to drop your gas tank to do that it is usually not worth the money.

Amanda: When was the last time the Gas Filter was changed? ...Also has the Distributor rotor been changed? The problem sounds like a clogged fuel filter...Changing the Rotor is a $5 good idea...See photos below...The filter and rotor can both be bought for $20...Once the filter is changed, i would suggest adding a can of SEAFOAM...Cost is $9 a can at most auto part stores...Pour it in the tank the next time you fill...It's an excellent internal cleaning product...

Check fuel pressure it should be 41-47 with key on engine off more than likely this will be the problem.

Hello. The GMC Sierra has an electric fuel pump so you should ensure that its fuses and relays are working before checking it. You may need to clean your fuel pump or replace it if your gas tank is not empty, but your vehicle has difficulty getting fuel. The GMC Sierra comes in a variety of styles and trim levels that can affect the replacement fuel pump you choose.

Could be spark plug wires need replacing. Go out at night and start car in dark with hood raised. Look for little flashes or sparks. If nothing then try misting a little moisture from a spray bottle and see it you can't replicate the problem. I am assuming the moisture is causing the wires to arc and once the engine heats up it dries things out enough thatit runs okay

Check the fuel filter to see if it is plugged.
Remove the fuel filter, and blow air through it in the normal direction of fuel flow. You should be able to blow through it very easily. If it feels restricted, try blowing through it the opposite way, and if there is a lot of dirt coming out, you have found a common cause of this problem. Hope this helps.

The CAMshaft position sensor is faulty.

its vapor locking,remove fuel cap and drill 1/8 hole in it or replace cap

check th fuel filter - does this happen when below 1/4 tank of gas? there is a filter in there too. a clogged filter will be worse at acceleration - if it is at 1/4 tank or less when this occurs - try filling up and see if that helps - when you drop below 1/4 tank you will **** up trash from the bottom of the tank! hope this helps
