What year and which engine?
Will it start if you spray carb cleaner into the intake while cranking?
If yes, then either no fuel pressure(need to test with a gage) or the injectors are not firing(Security problem?).....
If no, check for spark on all cylinders.....
also pull the vac line to the fuel pressure regulator and check for fuel in the line....
Any codes?
Before the no crank problem, the car started ok?
