Recent work done:

I've replaced the timing belt because one idler had lost its plastic covering and the belt was slapping the timing cover. Engine was running fine before this.

I've made sure the that the cams and crank were at the timing marks before removing the belt. After replacing the belt and water pump, the car will not start.

Tests done:

Injectors - I put an LED on the injector wiring connector; the computer is pulsing the injectors. With a stethoscope, I can hear the injectors clicking when

Plugs - All plugs are firing. I checked them all with a timing light.

Fuel rail - I've installed a fuel pressure gauge, which shows 40 PSI when the is in the key on position and 35 PSI when cranking engine.

Any help you guys can give would be great. I can't believe that this car isn't starting, since it is getting fuel and spark. If it were out of time, then it would at least back-fire, AFAIK.
