I drove my car fine for one night, it started and went that day and ran fine. Then I go out to start it and it wont. It is like it cranks and like something is telling it to not let the gas. Checked the fuel pump and its going, their is psi pressure. Someone said maybe the anti theft got on some how? Just wondering before I take it to the garage

Do below to determine if its fuel or spark problem

Disconnect a sparkplug wire or 2 and ground it to the engine -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, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it
