Nissan Pulsar Engine Problems

Why don't the gears shift in my 1996 Nissan Pulsar?

Answered by CarsGuide 15 Aug 2020

If the gearbox won’t shift gears, then the vehicle won’t be able to accelerate any further once the engine has reached its maximum speed in the gear in which it’s stuck. That’s probably (I’m guessing) why the car feels like it won’t go any faster.

There are any number of reasons for an automatic gearbox to remain in one gear and refuse to shift. They start with low transmission fluid and go all the way up to a major internal failure or even a computer-related problem. There’s no real way to diagnose these possibilities remotely, so you really need to get the vehicle to somebody who specialises in automatic transmissions and get them to take a close look and diagnose the problem.

If it’s a major problem with the gearbox, your decision then becomes one of whether the vehicle itself is in good enough condition to warrant spending the money. A major job such as a new transmission and the labour to fit it could easily wind up costing more than the car is worth. Sometimes you’re better off scrapping the vehicle, cutting your losses and moving on to something newer and safer.

Nissan Pulsar 2005: Why is there a banging sound when I start the car?

Answered by CarsGuide 22 Feb 2020

If the noise sounds like a dull thud or knock from deep within the engine, then I have bad news. Something inside the engine is probably trying to get out. And if it does, the engine will be instantly turned to junk. The worse news is that it probably already is (junk) even though it’s still running, because the damage has already been done. From the sound of things, your engine is perhaps only a few seconds away from exploding expensively.

Noises like this are usually caused by wear in the bearings – typically the con-rod bearings – and while they can be fixed if you do so before the engine grenades, it will always be an expensive job. In fact, it would likely cost more than the actual value of a 2005 Pulsar itself.

The best advice, then, is to let a mechanic have a listen to see if it’s as bad as you’ve described. From there, I reckon a second-hand engine form a wrecked Pulsar would be your best bet if you’re determined to keep the car.

It would be worth having a mechanic check it for you. It could simply need a tune up, new plugs, plug leads, clean of the throttle body, or idle adjustment.

Nissan Pulsar 2003: Ignition problems

Answered by CarsGuide 1 Mar 2019

It could be the battery; it could be the fuel pump. I had a similar problem that turned out to be a blown head gasket, so it could be worth doing a leak test.

Nissan Pulsar 2001: Check engine light

Answered by CarsGuide 25 Jan 2019

It could be a fault with the computer, but I would have it investigated rather write it off as a computer glitch. You could have a problem with the cooling system, so I would have a mechanic investigate it.

Is my car running on bad fuel?

Answered by CarsGuide 14 Sep 2018

It could be due to bad fuel. Run it out as best you can, or drain the tank, and refill with fresh fuel from another servo, preferably one that sells a lot of fuel so you can be confident the fuel is fresh.

If it still does it then look for other causes, such as fuel filter, fuel pump, air filter, throttle body, spark plugs.

The first thing to do is to give it a tune-up, with new spark plugs, replace the air cleaner, and clean the throttle body.
