'04 Tahoe won't start

Cylanoed or starter going bad

did you ever got this fixed im having the same issues but when its cold it wont start replaced battery, plugs, ECM, checked starter, its good took it to a shop, fryed the ECM charged us money, took it to a dealer ship they say the last machanic put realys in the wrong spot ,and they put the ECM in and it started right up told us to come pick it up and we get it home and nothing same problem they charged us 250$ cant find this problem any place on the internet

I'm had same thing...k... Go to fuse box under hood by battery in front ..trust me take off cove then . In screw ground off front of box should be two little screws holding the whole box...now flip it over an in one of them clusters of why it is you're going to have a busted why I probably look for a green put something in the top but it should be close to the plugs a vibrate and those wires split and if that ain't the case go underneath your door the driver's door you're going to see two wires grounded there brown sand get a grinder grind a s*** out of that body and reconnect the ground cuz that rest will stop your calf it'll turn turn turn crank no start no code if that's what you're getting check there first
