4 Wheel Drive/SUVs: Fuel injection, nissan pathfinder, o2 sensors

Question
QUESTION: I have a 1989 Nissan pathfinder, 3.0 V6 TBI does it have 1 or 2 fuel injectors

ANSWER: John,

The fuel injectors (2) are small solenoids that allow fuel to be injected into the intake manifold. They are contained in the throttle chamber. The injector receives a ground circuit from the ECU in terms of "Injection Duration". The voltage applied to the electrical windings pulls the needle valve up allowing fuel to flow through the nozzle.

WARNING: The positive circuit is always "Hot" at the injector terminals when the battery is connected.

QUESTION: Os it common for them to go put. I was going down the road and it started to bog down like I was out of gas now I cant get ot to start

Answer
O2 sensors do go out fairly often.  The problem is that when they do, they usually don't cause this problem.  This sounds more like a fuel pump problem, or a plugged/faulty catalytic converter.

I would have the fuel pressure and the catalytic converter tested.
