2005 Chevrolet Tahoe Crank no Start

In this video I attempt to diagnose some electrical issues going on in my engine management. The problems spread to others modules during my diagnostic indicating a CAN BUS issue which is controlled by the PCM

My Tahoe just started this .after it's sat for a few days I have to turn it on and off multiple times.it will try to start then die over and over.and sometimes turn over like an older car.then start and die.

Good information bud mine won't crank from key switch but I can start it from starter relay after it starts has information on dash says loss engine power if u let it warm up to 200 degrees and shut it off wait 5 mins and start it runs fine no codes in message center then if u drive it the engine shuts off and won't start back for hours it sounds like same issues u had what u think man

so kind of same deal with my 04 I had a new motor put in it and after 3 months it started going thru throttle body's then mass air flow 02 sensors then catylaic converters failed ,then crank position sensor replaced after it quit starting it started then ran rough and died and now it won't start at all. no codes at all other than the throttle body and when I mean it started going thru throttle body's I mean 1 every 30 days for 6 months . had it to several shops they threw parts at it and it still will not start.

Mine takes 3 cranks to start most times but sometimes it starts on the 1st crank

I just hit the submarine button. My wife has the exact same car. She Called me while ago and said her car would not start. It would turn over and over and over but it would not start. Well for some reason she pulled the dipstick and check the oil and it was not reading any oil. So then she put oil in it and it fired right up. Did the oil really fix that car or is that just a coincidence?
