2011 GMC Sierra 5.3L Turns over but won't start

[Sbaasen]

I have 155,000 miles on my truck and the other day it gave me one hard start then drove fine. The next day I woke up and it didn't start. It tries but doesn't start. I have check the fuel pressure which is good. I replaced the crank sensor thinking that was it, but still no start. I checked to make sure I was getting spark and I am. Any ideas??

Here is a video of what it sounds like when I go to start

Can you give a little more detail about what it's doing? In the title it says "Turns over but won't start" but in your post it says "it wouldn't turn over?" Just need a little more description of whats going on.

With that kind of mileage it's time to check compression.

[redvett]

Start with the basics, check compression, spark and check fuel pressure with a gauge. What M&Y?

[Sbaasen]

Fuel pressure is good, engine has spark, but I haven't checked the compression. I am having it towed to a local shop tomorrow. Its an 2011 GMC Sierra 5.3L

What is your fuel pressure at key on engine off? Post it please. A lot of people post "pressure is good" only to find out the figure they are using is incorrect

Have someone turn the key while you sit by the fuel tank (in silence) and listen for your fuel pump you don't need to check the fuel pressure at the rail.... just listen for the pump if you hear it engage and still get nothing then check other stuff

 

could also be your relay

Something I learned recently, just because you hear (or don't hear) the fuel pump, does not mean it is functioning properly.

I guess I have noisy fuel pumps in my car and my truck then
