1999 Ford Escort Zx2-ignition coil? Timing belt? Injectors?

I have 1999 Ford Escort Zx2, 2.0 L, automatic transmission, 126, 00 miles. I changed the oil, oil filter, air filter, and put some Lucas fuel treatment in the fuel tank. Drove it home that night (approx 40 miles) and it wouldn't run the next morning. I managed to get it started by giving it quite a bit of gas, but then it would die, and now it won't start at all. I changed the spark plugs and plug wires and changed the fuel filter. I have pressure from the fuel pump (got sprayed pretty good) and I have spark. I'm thinking maybe the ignition coil or maybe even the timing belt. Oh, and when I took the 3rd and 4th plugs out they were covered in kind of oil, but it still smelled like fuel. Anybody know what's goin on here?
