hi i have code u0029 poor bus a connection. 

for chevy truck most say its there radio issue but issue i am having is crank no start. i have spark but have not tested fuel yet. i cant hear fuel pump turn on. anyone have any other thoughts then checking fuel?

i knocked the gas tank with a hammer on its wide side to make the least amount of possible damage and transfer most energy thru. at the same time i used the autostart function and it started up. this was before even trying again on its own if it would start. as i drove home i heard one pop and scanned again and got a new code for lean on bank one and two. no check engine light just in history.
