1998 ford contour 2.0 zetec timing/flex plate?

:banghead: i have tried checked and tested everything on this engine and it still will not start...it sounds like it might want to but does not...it has always lead me back to timimg...unfortunately the computer contains no codes...i could really us some new ideas...i hope someone can help me and if you need some more information please ask me and i'll get back asap..thanks in advance..tom

new timing belt installed properly
all sensors check out ok
fuel pressure 38# and holds
injectors working properly
good spark

questions:(this is how desperate i am)

1. would a cracked or broken flex plate cause this no start condition?

2. is there a definitive test to eliminate the flex plate as the culprit?

3. is it possible to inspect the flex plate with a flexible camera? (i'm thinking maybe through the starter hole or even the crank sensor hole)
