Car died... won't restart, UPDATE: Car still won't start... please help Options

Car cranks/turns over just fine. Has plenty of spark and fuel. Car was acting squirly day before it died. When leaving work, the car started and idled very roughly ~600 rpm. Held my foot on the gas for about 15 seconds seemed to clear it up, drove home without any problems. Started up next morning and drove to work without any problems. When leaving work, car started, ran for about 5 seconds and promptly died and could not be restarted. Unfortunately a buddy of mine was checking fusses and I believe he reset the CEL because it's not throwing any codes. Anybody got any ideas?

Update: After changing the timing belt and the various seals, the car still won't start. It's exhibiting all the original symptoms. It just cranks over, it doesn't even try to start. I've re-checked the timing belt and it's exactly where it should be. The fuel filter, plugs, wires, cap, and rotor are all new. I've checked the fuel pressure it seems to be okay (44 psi). I tried starting fluid and it doesn't even try to start. Does anybody have any ideas where I should go now?
