I have a 96 Oldsmobile aurora 4.0 and it will not start. I started the car and it started right up no prob and pulled it in the garage. I then jacked up the front end of the car both tires off the ground and changed the oil, antifreeze, and front spark plugs gaped at.050 thousandths. I started the car while still on the jack stands and it started right up then started running rough and died. I thought nothing of it and went to start changing the front left break pads and when I was done I tried starting it just cause it was bothering me and it wouldn't start. So I put the car down off the stands checked all my fluids and they where at correct levels but car still wouldn't start. Oh I also put 3 quarters of a can of sea-foam in the gas tank that only had 1 quarter of a tank of gas in it, and put half a can of sea-foam in the oil crank case. This was earlier before I tried starting it. My wife told me she put regular unleaded gas in it and it is suposed to have premium only of a 91+ octane minimum. So autozone told me to put half a bottle of 108+ octane in it that it would be fine even no I had all ready put 3 quarters of a can of sea-foam in it as well. So I did and still nothing. I have checked the fuel pump relay and it is good and working, the fuel pump was replaced 2 months ago, and I just replaced the fuel filter tonight because when I tapped on the fuel filter while my wife turned the key it started up and ran for about 30 seconds and then died and would not start again. I sprayed ether in the air intake and it started then died after 2 seconds. I had my wife turn the key while I depressed the fuel pressure relief valve on the rail and it doesn't seem to be getting any fuel pressure all the time. It was after I replaced the fuel filter but then shortly after stopped. I have seen that some of these same models have a fuel cutoff/inertia switch but I can not seem to find one. I have looked in the trunk, and under the driver and passenger dash and glove box. If it does have one I don't know where it is. I have my battery on the charger now I drained it trying to start it so much. I have EXPLAINED as much as I can. PLEASE HELP
