Check your fuel pump, you will need a fuel gauge, hook it up to the fuel rail and check to see what the pressure is...
does soind like fuel pump tap on bottom of gas tank,you dont need a fuel press gauge to check just turn key on and on fuel rail is a fitting that has a black plastic cap twist it off,get a rag and use a small pocket pin push it in looks like a air stem on your tires,if it sprays then it's probably o.k.if it just trickles than fuel pump is going out,oh yeah check the little yellow fuses in the engine compartment,it could be burnt its for power for a cell phone sometimes that will kill engine
You need a min. of 56 lbs. to 62 continuous pressure, Like joemom says, check the fuel pressure.
The oil thing is another problem, longs your motor is still turning over, depending on how far you drove like this, it is possible that the lifters would need to get pumped back up, I don't know, try cranking it over for a bit, foot off the gas, see if it starts, If not, have to check fuel pressure with a gage.
