Does it oscillate or is it only reading 3.3 constant?

oscillates

people have told me timing chain, injectors, fuel pump, camshaft sensor, o2 sensor, ect ect ect and i just dont know where to start, its getting expensive replacing things hoping it will do something

is it normal for the fuel pump to only pump fuel when cranking and not when the key is turned on?

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.

Any idea where the afr sensor is on this model? I've been looking for schematics online but havnt found anything
