Timing Belt Install - Driving Me Nuts!!!

[Grant Lenahan]

Mohammad,

Two things catch my eye.  1) the job really should be done with a cam  
locking tool to keep things from turning.
2) I'm not sure what you mean by "tried starting the car with timing  
off but it won't start".  Huh?  Of course not, the valve train isn't  
spinning. Also, if it WERE to run, you would probably destroy some  
valves. I'm obviously missing something ---- or you are.
