Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Is the security light on when trying to start it?Does it flash or is it on solid when cranking the engine?
DO NOT let them put a fuel pump in the car.
It has lost the programming on the key and needs a locksmith or a dealer. The immobilizer has turned off the fuel so the car won't start.
A fuel pump will not repair it and will be a huge loss of money.

I am saying if that security light is on solid, the immobilizer is set. If the immobilizer is set and has the car shut down, then a fuel pump won't do anything. It's very common for shops to replace the fuel pump when this happens.
It sounds like it needs a nissan dealer before you go any further. If the immobilizer is working only sometimes, then it will need repair.
