I have a 2001 Corvette that started to idle really rough at times then after you turn it off and back on it was perfectly fine. Now it will not start, after several attempts it would start just fine then after turning it back off it would not start back up. What's wrong?

Cranks but no start condition-do below to determine whether it's fuel or spark issue.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

It does have a spark. Checked the Fuel Pressure it was at 45psi when it did start it would falter and die. Kept checking the fuel pressure and it would swow 0 then turn the key off a couple times then it would be 45psi. You can hear the fuel pump come on and start it just runs real bad but then you might not hear it come on and the fuel pressure would be 0. I was starting to think it is the FPR unless it shuts the fuel pressure to 0. Reading about the steering lock theft system there was a section in it that talked about if lock would overide the system it would shut the fuel off so it could not be driven. There is a recall on this problem and I do not know if this car has been updated. What do you think know?
