Lately my truck cuts off after hard acceleration only. I had changed my alternator not to long cause I was having dimming lights and it was bad I also changed my battery to. Now when it shuts off my battery light comes on and my fuel light. So I don't no if it'* my fuel pump or cam/crank sensor any suggestions

And no check light

Could theses messages cause my cut off issue. Like if I press the acceleration a like more down I will get Traction control active message and it will cut power to the wheels. With no check light I can't figure what to look for .<br/>Ignition <br/>Spark plug wires / spark plugs<br/>Cam/crankshaft sensor <br/>Throttle position sensor <br/>Fuel pump

Service stability will not shut down the engine. Even if the CEL is not lit, it still might be throwing codes. If you don't have a code reader, take it to Autozone and they will read it for free.

I called auto zone they said if it'* no check light then the scanner won't read. Now all the sensor I listed they all can cause the engine to stall. I'm at lost I would hate to take it to the dealer and then they don't find nothing. Well what ever is cause me to stall on hard acceleration is affect the way my truck drives. I'm a try to change the throttle position sensor and crankshaft sensor and see what happens. Note my alternator and battery been change a month ago so they can be ruled out next I will try my spark plug wires and spark plugs

Autozone'* response is not correct. I've had several situations where the CEL was not lit but codes where thrown and could be read.

Took it back to autozone nothing showed up. So I don't no with this truck

Question for any one my tank is a 32 gallon I have the xl 1500 6.0l. I notice once the low gas light comes on I put in 10 dollars of gas at 2.19 divide into 10 that'* 4.5 gallons my need goes to a quater tank. I no half a tank is 16 gallons so a quater tank should be around 8 gallons I'm not mistaken. So my conclusion is that my fuel pump isn't accurate showing me more gas then what I have. So could that be my problem I'm having?

What I would recommend is that you fill the tank to at least 3/4 or full and then see if under hard acceleration it continues to stall.
Possibly with less fuel, it'* sloshing around a bit, and accuracy may be off?
Fuel pressure tests /regulator/ psi at rail / fuel filter been changed?
What year is your Denali? Can you add that to your signature line, be great if you could.
Pro shop Scanners like Solaris & ultra can better diagnose & find codes.
With service stability there are codes stored, and the proper scanner will show them.

My truck is a 03 I change my fuel pump 2 years ago I haven't tried 3/4 of gas to see of it would stall I'm guessing if it does then the pump no good
