Default 97 Bonneville will not start

My 97 bonneville cranks but will not start. I have replaced crankshaft sensor and camshaft sensor. Fuel pressure is 45 psi, the VATS seems to be working because the security light comes on for a few seconds and goes out. Not sure what else to check??? Please help as I am lost??

when you crank. If it'* clicking, you have fuel pressure, and spark. Try flooring the gas peddle, and crank it. You may have flooded it. Flooring it will shut off the injectors and clear the cylinders.

I am not sure if the injectors are clicking as I crank but when i had my spark plug tester hooked up I am getting spark plus with the fuel pressure guage hooked up I get good pressure when cranking. I did the dump and still will not start. I also have let it sit a day without me starting it to ensure I did not flood it but still no start.
