Check for spark at plugs if no could have faulty ignition module or ignition coil could have faulty crankshaft position sensor.if you are getting spark ignition timing off due to worn timing chain.

It has to be done with a scanner. You can adjust this distributor, but there are no timing marks to watch as you move it. There is a timing mark on the balancer and on the timing cover for referencing Top Dead Center #1 cylinder only, but it is only used for dropping the distributor in to get the engine up and running. A scanner is needed to properly adjust the timing. Connect the scanner and look for a data parameter labeled ‘cam offset’ or possibly ‘cam ******.’ It will be listed in degrees. Start the engine, and bring it up to 1500 rpm. Note the reading. If the timing specification is not within plus or minus two degrees of zero, you need to move the distributor. You can move the distributor with the engine running but the timing will not change. After you move the distributor, the ignition has to be cycled off to let the computer learn the new timing spec. Restart the engine, bring it up to 1500 rpm and see what the new spec is. You must repeat this procedure until you get the timing into the specification as mentioned above. Once you have it set to spec, the code should clear.

Check the fuel pressure on the fuel rail on top of the motor. Diesel fuel tends to be "dirtier" than gasoline, and I'd be willing to bet the fuel filter is stopped up.

yep i seen it in happen .i was at a gas station a guy drove car to the gas station on empty.he fill his tank up .could not get it to crank .some cars you have to restart fuel pump when run out of gas. like chrysler.you use a scanner. but chervrolet you run low over heat damage the pump.it has to stay submerge gas to keep it cool. check fuel pump pressure.it should be 41 - 47 psi.

sounds like youve really done your home work all that comes to mind now is try a cam posistion sensor this would keep your car from starting as well if that is good you can aslo try a crank sensor. you will get all of the readings that you are getting and these sensors can still be bad.

try to spray some carburetor cleaner inside where the air goes in the engine...it will clean the system and it might start...
press some gas when you try to start the vehicle...
good luck!
