Need advice

no i know that. The only reason i asked is because both my tahoe and suburban if the fuel tanks on E and it sits over night it takes an extra couple seconds cranking before it starts
so i was makin sure that wasnt the issue

if you have a fuel pressure tester by now you should check on that. you would be looking at the pressure charge rate when on e and say a half a tank. you should not be having that issue. if you think it took longer because it was sucking in air from being so low then you would notice that in the engine running. i would recommend you get some sensor data when this does and does not happen so i can analyze it for you.

its like it takes a few extra seconds to crank when the low fuel light is on and its been sitting all night and prolly most of the next day
i didnt think it was taking longer because it was sucking in air becuase of how low it was
i figured it was an issue of the pump takin longer to prime
