Bad opti = but Plugs have spark?

Could a opti be bad (not allowing the car to start) although still making spark at the plugs?

Not likely. Can you check fuel pressure? If not try squirting about 2 ounces of fuel in the TB and then crank it over. If it starts and shuts down, you have a fuel problem.

You didn't let the tank get bone dry and then fill er up lately did you?
