I need to be pointed in the right direction to diagnose this crank no start issue in my trailblazer.
Possible clues, for a while I started having a longer crank before the engine would start, maybe 3 to 4 seconds, which has been going on for years so it became the norm. A few times over the past couple years I'd go to start it but it would die out because I'd let go of the key before it fired up, due to the longer crank. Other than that it has no issues, no rough idle, never stalled on me.
Now it just doesnt start at all, I can crank it until it automatically stops cranking and it wont fire up, and this happened out of no where, it wasnt a gradual thing, it went from getting in it and starting every time, to one day only cranking and not firing up. I pulled the codes, which seem to be no help but they were p0128 p0463 p0506. I hear the fuel pump energizing when I turn the key to the on position.
It's cold and snowing where I'm at, so I want to have some ideas on what to check before going out there and freezing (so I haven't checked anything yet other than fuses, codes, and listening to the fuel pump).
