+1 on on above. Good point trinity_gt.
To add, how old is the gas? Could this just be "skunky" gas? Or water in the gas?
To the OP, it may seem like a silly thing, but try cycling the key on/off/on/off serveral times without cranking. Each time the key is cycled, the fuel pump should run for a few seconds. This allows fuel pressure to build.
Just to confirm that the Theft lights stays off during the failed cranking attempts?
Again, if the battery and/or the alternator is weak, this can cause no starts. I personally have seen cases where a weak battery appeared to spin over fast enough to start but didn't. As soon as a jump was applied, the motor would fire up. Don't discount the problems a weak battery can cause on a computer controled car.
In the end, this may turn out to be a fuel pump. But it just seems to make good sense to rule the other possible causes in/out along the way.
FWIIW, if the fuel pressure at the rail really was ZERO, the car would never start. I suspect the OP is not pushing down the pin enough on the schrader valve. Or the tester is not pushing the pin enough to open the schrader valve.
