1 of the four things the OP mentioned is NOT correct. Probably the timing belt.
That’s my thinking, also, E-E. If the belt is retarded 1 cog at the crank it might not start unless the ignition is moved ahead.
Well today I unplugged the computer, and after plugging it back up I was able to get the car to start. Oddly enough I just put the computer in about a year ago. 16 days shy of a year to be exact.
I withdraw what I was going to say!!
