car started when i attempted to warm it up a couple of days ago. started fine but shut-off while i stepped inside to get coat and shoes on. i stepped away for approx 5 mins. when i returned to the car, it had shut off. i attempted to restart it and all attempts failed. changed plugs and fuel filter. lost at this point...

Do you have a check engine light On or has flashed prior to this problem and when was last tune-up??

Cranks but no start condition:

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -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,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
