@stacy503 ,Stacy, No fault codes. I take it that the engine turns over and does not start. Has the vehicle had a tune up recently, if not start with a new set of plugs and check them for spark by grounding out on metal engine/bracket and turn engine over by key and observe for spark between electrode and tip of plug. No spark then the problem will be in the electronic ignition system, bad coil, relay/fuse, distributor,etc.. Do you hear the fuel pump start and run a few seconds when ignition key turned to on position, if not give a little spray of fuel/starter fluid directly in the throttle body and try starting. If engine starts and runs until fuel sprayed used up, this is telling you there is an issue in the fuel delivery system, clogged fuel filter,blown fuse/relay, faulty pump. A slipped/broke timing belt. clogged exhaust/catalytic converter, completely clogged air filter,faulty ECM, bad wire/connection etc. could also cause no start condition. You may have to have a good local mechanic have a look and diagnose the issue.
