    No,, you haven't tried 'everything'! First:: Got to know how much fuel pressure it has when tested with a gauge!!

    Pressure is fine. I'm thinking it could be cam shaft sensor

    No that aint it! Got to know what the fuel pressure is when tested with a guage!!! Reading in psi. Until that is known can't go further! Think about this, ran out of gas, ok so why do a bunch of work on anything other than the fuel system? Are you 100% sure it was actually OUT of gas, or the fuel pressure was just 'inadequate' from a failing pump?? Got to test it! Then we can go on to the next step. It's like walking down the stairs, if you miss a step you will bust your a..! To successfuly reach the bottom ,of this, can't miss a step! Check the d..n fuel pressure!! Post test results and we will get you back on the road!

    many GMs will run with cam sensor CMP unplugged, just not the CKP crank sensor. Also you can have fuel pressure but if it is too low( most modern GMs need 30 PSI min just to start and run bad, the spider injectors need over 40 to barely start and still would run poorly, so having pressure does not mean that there is enough pressure at the required volume.

    You can try (very dangerous)some flammable spray like starting fluid or brake cleaner, spraying lightly while cranking and if engine runs you confirm that you have a fuel problem. This should is normally only done with professionals as it is possible to have a back or misfire that can start a fire. If engine runs on a shop type fuel supply then as pushrod suggested you may have a fuel pressure problem which could be a electrical problem with pump or injectors or mechanical problems like filter, pump, pressure regulators of injector(s). If you still can not get going you can call Roy 757-456-0722 for to arrange a diagnostic and request/reserve a free loaner/rental vehicle while being diagnosed/repaired.

    Did you put at least 3 gallons or more of gas in after it 'ran out'?
