If it's catching like that, that means the car is pretty much fine but there's a weak link somewhere. You have fuel but you may not have enough - it could be a dead or dying fuel pump. The other possibility is the vacuum leak - like I said, check every vacuum hose, make sure they are all in place and nothing is cracked.
How did the car run when it did fire for a short time? I did it just sputter, or did it seem to run fine? You can also check the crank position sensor, see if the lead has any breaks or exposed wires. It's on the front of the engine, right above the harmonic balancer. Some older engines have it on the flywheel... your repair manual will say.
I would start by trying a different fuel pump - maybe see if you can borrow a used one.
It's not oil in the exhaust.
