The car does not pull any trouble codes,It runs have assed most of the time,but has all new plugs,wires,coilpack and then some.It will just not start sometimes,it will start then shut right off,You can disconnect the battery do what ever and then maybe a hour or maybe a week it will start again and drive,then it just repeats itself.I believe it is a security or computer issue but sense it pulles no codes its like a ghost,please help

If it's not a security system problem, I would replace the Ignition Control Module (ICM). Security system issues have been common on those cars, however.
