My wife was able to start the car and drive to work, but after work, she was not able to start it. The car turns over, but will not fire up. I checked the spark plugs and they all look fine, but I did notice some oil coming from the ones on the back of the engine. Just a few days ago it almost didn't start, but I simply turned the key off and then back on and it started right up. The plugs have been changed recently, but I'm not sure about the wires. I heard it could be the coil pack or an oxygen censor. What do you think?

Cranks but no start condition:

Fuel and Spark:
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.
