I got a 2000 Nissan Quest that won't start. the engine turns but won't fire seems like it's not getting fuel. The pump is working starter and battery are good. Someone told me to rest the anti-theft system, but I don't have the key fob anymore. What can I do to yry to do it myself. I can't afford to pay someone to do it.

Okay, here is an easy test to see if it is the immobilizer: put the key in and turn it on. What does the security light do? If it goes out it's not the immobilizer, if it starts blinking then the key isn't being recognized and you either have a bad key or the more common issue which is the module in the column has failed. Now if you don't see a security light come on at all don't be surprised, the immobilizer wasn't standard on the Quest until after 2004 and if you are hearing the fuel pump run it also isn't the immobilizer as it shuts off the fuel pump.
I would start with the basics, you say it has fuel, have you tested for spark? I would start there, remove a plug on each side and see if you have spark. This might help as a start.
