yes.

3.3v is running lean. It should be around 2.5V if your running regular gas.

Try unplugging the AFR sensor and see if your car runs better. If it's still the same, you'll have to check your fuel pressure with an in-line gauge you hook into the fuel line right at the fuel rail. From your description of having to crank for so long and running lean once running, it sounds like you have very low fuel pressure. The pump might have developed an internal leak or the built-in pressure regulator failed.
