Your first place to start is to see if you have pressure from the fuel pump. With the key on but car not running you should hear a buzzing sound from rear of car near the fuel tank. If you do hear this it is a good sign but you still need to make sure you have good fuel pressure to the injectors. Remember any time you open fuel lines(even for a filter change ) you need to purge the fuel system of air that has gotten into the system. You can do this easily by turning the ignition switch on(do not start) and off several times. This allows the pump to pressurize the fuel system. You can get a goo idea if you have good fuel pressure by taking off the inlet line to the filter and checking for feul flow there. For the Nissan you should be 40 PSI. give or take a pound.

Take an analog ohmmeter, remove connector from TP sensor, and touch probes on terminals of sensor, try combination of 2 until you see reading increase as gas pedal pushed & decrease as pedal released by someone, while engine off, and key off.. Have them slowly, & gradually push pedal, as you watch meter. Reading should increase slowly & gradually as well. If you see it climbing, then quickly drop off, then jump back up, it's faulty. Try to concentrate more on the position of gas pedal where you experience the engine cutting out. Costs nothing to try it.

SOURCE: pathfinder, cuts out when start out then why drive

Your car could cut out for many reasons. Here's the reason and solution to my own pathfinder cutting out:

One day, out of the blue, my Pathfinder engine cut out as I started to drive. It then cut out randomly. The way it was failing 'felt' electrical in nature, like a connection was going bad.

So, I'd start the car and quickly run out and start tapping on all things electrical. The MAF, or Mass-Airflow Sensor (not to be confused with MAP, the manifold air pressure), is located on the front airbox-airtube assembly and was a natural to tap on. The instant I tapped on it, the car died.
Did it again, and again, and again. The Mass Airflow Sensor was to blame.

I looked at the prices of these buggers, and they were in the $300-$800 range.

For that price, I'm going in!

I removed the MAF sensor by unscrewing the 4 screws.

I then managed to gently pry it open. What I found was a little control board encased in a jelly, presumably to isolate the board from the elements, and three little thin wires leading to the external connector. Without even having to break out the multimeter, I could tell that one of the wires had broken due to vibration fatigue or some other manufacturing defect. I recall I had to break all three wires to get the thing to open fully.

Soldering this was very difficult due to the presumably silicone jelly. It made the metal very resistant to bonding with solder. Without digging too much into the jelly, I exposed all wires and eventually, with scraping, fire, and flux, managed to get solder to stick decently to the various wires, adding my own jumper wires to make it easier to bridge the gap and close the case.

I needed to make this fix road-worthy, so I folded their wires around an insulating piece of clear plastic I cut from some plastic packaging material. The wires folded nicely into place and the case closed.

Several years later, the fix is holding strong.

1998 buick lasabre changed plugs and wires when hit gas cuts in and out


I would try changing the fuel filter and/or pump. My brother had to take the exhaust system off the bottom of the car and then pull the gas tank to get to the fuel filter.

Hope this helps.

My problem was after I would drive the car and the engine would heat up. Once I parked and then tried to start it again while engine was still warm, it would not start. Strangely enough, a jump would solve the problem. But it happened over and over. Once we changed the fuel pump and filter, it never happened again. If you are under there replacing the fuel filter, I recommend changing the fuel pump as well. No sense in having to go through that awful hassle twice.

Engine cuts out


Adrian, try changing the fuel filter first and see if that does anything.
OR you might have got some bad gas somewhere with some water in it. Get some "Dry gas" at an auto parts store and add a couple bottles to the gas tank. I'd try this before you bring it to a mechanic.

Gas cuts out when i am driving then comes back. i got new catalytic converter. is it the fuel pump or fuel filter? help me please


One might consider changing the fuel pump and fuel filter to try to get rid of the lack of gas problem.

If the fuel pump is changed, the filter is a logical thing to change at the same time.

Good luck on this repair.
