Already did the new security program that took 30 minutes with the key.. the car did start once then turned the car off and tried to restart again and it would crank and not start again..

Fuel pressure & ignition spark test required.

Engine is getting fuel and I get sparks on all 6 plugs

'IF' it has the correct amount of fuel *PRESSURE* - adequate spark to spark plugs and good compression ... The SECURITY SYSTEM has disabled the injector pulse .. Hands-on 'testing' is required! http://repairpal.com/repair-shops .
